INTEGRAL IBIS Hard X-Ray Survey of Galactic Center
From August 23 through September 24, 2003, the INTEGRAL Observatory conducted a deep survey of the Galactic Center region with a record-breaking sensitivity at energies above 20keV. The authors analyzed the images of the Galactic Center region obtained with the ISGRI detector of the IBIS telescope (15 - 200 keV) and this table contains their catalog of detected sources. A total of 60 sources with fluxes above 1.5 milliCrab were detected in the range from 18 to 60 keV (1 mCrab = 1.36 x 10<sup>-11</sup> erg/s/cm<sup>2</sup> in this energy band for a source with a power-law spectrum with a photon index of 2.1) above a detection threshold of 6.5 sigma which was chosen to avoid the strong effect of systematic uncertainties. The nature of 51 of the 60 sources is known: most of them (38 of 51) are low-mass X-ray binaries, and the remaining 13 include 5 high-mass X-ray binaries, 2 cataclysmic variables, an anomalous X-ray pulsar, a soft gamma repeater and three extragalactic objects. This table was created by the HEASARC in February 2005 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/PAZh/30/430">CDS Catalog J/PAZh/30/430</a> (the catalog.dat file).

INTEGRAL IBIS Hard X-Ray Survey Above 100 keV Source Catalog
공공데이터포털
This table contains results from an all-sky survey, performed by the Imager on-Board the INTEGRAL Satellite (IBIS) telescope on board the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) observatory over 11 years of operation, using data acquired at energies above 100 keV. The catalog of detected sources includes 132 objects. The statistical sample detected on the time-averaged 100-150 keV map at a significance above 5 sigma contains 88 sources: 28 active galactic nuclei (AGNs), 38 low-mass X-ray binaries (LMXBs), 10 high-mass X-ray binaries (HMXBs) and 12 rotation-powered young X-ray pulsars. The catalog also includes 15 persistent sources, which were registered at a significance 4 sigma <= S/N < 5 sigma, where S/N is the signal-to-noise ratio, but at the same time were firmly detected (>= 12 sigma) in the lower 17-60 keV energy band. All registered sources are known X-ray emitters, which means that the catalog has 100% purity in this respect. Additionally, 29 catalogued sources were detected significantly in different time slices of the survey. In the reference paper presenting the results of this survey, the authors present a hardness ratio for Galactic and extragalactic sources, an LMXB longitudinal asymmetry, and a number-flux relation for non-blazar AGNs. At higher energies, in the 150-300 keV energy band, 25 sources have been detected with S/N >= 5 sigma, including seven AGNs, 13 LMXBs, three HMXBs and two rotation-powered pulsars. Among LMXBs and HMXBs, the authors identified 12 black hole candidates (BHCs) and four neutron star (NS) binaries. For this hard X-ray survey, the authors utilized all publicly available INTEGRAL data acquired by the IBIS telescope between 2002 December and 2014 January (INTEGRAL spacecraft revolutions 26 - 1377). The survey also contains private data from the M82 deep field (PI: Sazonov) and scanning observations of the Galactic Center (PI: Krivonos) and Puppis region (PI: Tsygankov). The survey sky coverage as a function of a 5-sigma limiting flux is shown in Fig. 2 of the reference paper. The peak sensitivity of the survey is about 2 mCrab (8 x 10-12 erg s-1 cm-2 in the 100-150 keV energy band). The survey covers ~10% of the sky down to a flux limit of 3.7 mCrab (1.5 x 10-11 erg s-1 cm-2) and 90% of the sky down to 25 mCrab (10-10 erg s-1 cm-2). The catalog has been compiled from sources passed through detection conditions in the reference 100-150 keV energy band on time-average sky maps (Section 2.1 of the reference paper) and maps built over different time periods (Section 2.2 ibid.). For all 132 sources, the time-averaged fluxes are given, even for those sources which were not detected therein. For some variable sources and for sources which were only detected in certain time periods, the fluxes measured in the specified time intervals are also given. Thus, this catalog has 50 additional rows for such entries, giving it a total size of 182 rows. This table was created by the HEASARC in November 2016 based on the electronic version of Table 2 from the reference paper which was obtained from the CDS (their catalog J/MNRAS/448/3766 file table2.dat).

INTEGRAL IBIS 9-Year Galactic Hard X-Ray Survey Catalog
공공데이터포털
The INTEGRAL observatory operating in a hard X-ray/gamma domain has gathered a large observational data set over nine years starting in 2003. Most of the observing time was dedicated to the Galactic source population study, making possible the deepest Galactic survey in hard X-rays ever compiled. The authors aimed to perform a Galactic survey that could be used as the basis of Galactic source population studies, and performed mapping of the Milky Way in hard X-rays over the maximum exposure available at Galactic latitudes |b| < 17.5 degrees. They used sky reconstruction algorithms especially developed for the high quality imaging of INTEGRAL/IBIS data. In their paper. they presented sky images, sensitivity maps, and catalogs of detected sources in the three energy bands 17 - 60, 17 - 35, and 35 - 80 keV in the Galactic plane at |b| < 17.5 degrees. The total number of sources in the reference 17 - 60 keV band includes 402 objects exceeding a 4.7-sigma detection threshold on the nine-year time-averaged map. Among the identified sources with known and tentatively identified natures, 253 are Galactic objects (108 low-mass X-ray binaries, 82 high-mass X-ray binaries, 36 cataclysmic variables, and 27 are of other types), and 115 are extragalactic objects, including 112 active galactic nuclei and 3 galaxy clusters. The sample of Galactic sources with S/N > 4.7 sigma has an identification completeness of ~92%, which is valuable for population studies. Since the survey is based on the nine-year sky maps, it is optimized for persistent sources and may be biased against finding transients. This table contains the catalog of 402 INTEGRAL sources exceeding the detection threshold in the 17 - 60 keV energy band. This table was created by the HEASARC in September 2012 based on CDS CATALOG J/A+A/545/A27 file catalog.dat. This is a service provided by NASA HEASARC .
INTEGRAL IBIS AGN Catalog
공공데이터포털
In this work, the authors present the most comprehensive INTEGRAL active galactic nucleus (AGN) sample. It lists 272 AGN for which they have secure optical identifications, precise optical spectroscopy and measured redshift values plus X-ray spectral information, i.e. 2-10 and 20-100 keV fluxes plus column densities. In their paper, the authors mainly use this sample to study the absorption properties of active galaxies, to probe new AGN classes and to test the AGN unification scheme. The authors find that half (48%) of the sample is absorbed, while the fraction of Compton-thick AGN is small (~7%). In line with their previous analysis, they have however shown that when the bias towards heavily absorbed objects which are lost if weak and at large distance is removed, as is possible in the local Universe, the above fractions increase to become 80% and 17%, respectively. The authors also find that absorption is a function of source luminosity, which implies some evolution in the obscuration properties of AGN. A few peculiar classes, so far poorly studied in the hard X-ray band, have been detected and studied for the first time such as 5 X-ray bright optically normal galaxies (XBONGs), 5 type 2 QSOs and 11 low-ionization nuclear emission regions. In terms of optical classification, this sample contains 57% type 1 and 43% type 2 AGN; this subdivision is similar to that found in X-rays if unabsorbed versus absorbed objects are considered, suggesting that the match between optical and X-ray classifications is on the whole good. Only a small percentage of sources (12%) does not fulfill the expectation of the unified theory as the authors find 22 type 1 AGN which are absorbed and 10 type 2 AGN which are unabsorbed. Studying in depth these outliers they found that most of the absorbed type 1 AGN have X-ray spectra characterized by either complex or warm/ionized absorption more likely due to ionized gas located in an accretion disc wind or in the bi-conical structure associated with the central nucleus, therefore unrelated to the toroidal structure. Among the 10 type 2 AGN which are unabsorbed, at most 3-4% are still eligible to be classified as 'true' type 2 AGN. In the fourth INTEGRAL/IBIS survey (Bird et al. 2010, ApJS, 186, 1, available in the HEASARC database as the IBISCAT4 table), there are 234 objects which have been identified with AGN. To this set of sources, the present authors then added 38 galaxies listed in the INTEGRAL all-sky survey by Krivonos et al. (2007, A&A, 475, 775, available in the HEASARC database as the INTIBISASS table) updated on the website (http://hea.iki.rssi.ru/integral/survey/catalog.php) but not included in the Bird et al. catalog due to the different sky coverage (these latter sources are indicated with hard_flag = 'h' values in this HEASARC table). The final data set presented and discussed in the reference paper and constituting this table therefore comprises 272 AGN and was last updated in March 2011 March. It represents the most complete view of the INTEGRAL extragalactic sky as of the date of publication in 2012. This table was created by the HEASARC in October 2014 based on CDS Catalog J/MNRAS/426/1750 files tablea1.dat and refs.dat. This is a service provided by NASA HEASARC .
INTEGRAL IBIS All-Sky Survey of Hard X-Ray Sources
공공데이터포털
The INTEGRAL IBIS All-Sky Survey of Hard X-Ray Sources table contains the results from a paper which is the second in a series devoted to the hard X-ray (17 - 60 keV) whole sky survey which has been performed by the INTEGRAL observatory over its first seven years of observations. This table contains the catalog of detected sources and includes 521 objects, 449 of which exceed a 5-sigma detection threshold on the time-averaged map of the sky, and 53 which were detected in various sub-samples of exposures. Among the identified sources with known and suspected natures, 262 are Galactic (101 low-mass X-ray binaries, 94 high-mass X-ray binaries, 37 cataclysmic variables, and 30 of other types) and 221 are extragalactic, including 217 active galactic nuclei (AGNs) and 4 galaxy clusters. The extragalactic (|b| > 5 degrees) and Galactic (|b| < 5 degrees) persistently detected source samples have high identification completeness (respectively ~96% and ~93%) and are valuable for population studies. The current INTIBISASS table is based on the data provided in Krivonos et al. (2010: Paper II below) and replaces the earlier version available at the HEASARC from February 2008 to December 2010 which was based on Krivonos et al. (2007). This table was updated by the HEASARC in December 2010 based on the CDS catalog J/A+A/523/A61 (specifically, the table2.dat and refs.dat files). It was originally created by the HEASARC in February 2008 based on CDS catalog J/A+A/475/775, which was superseded by this version. This is a service provided by NASA HEASARC .
Fifth IBIS/ISGRI Soft Gamma-Ray Survey Catalog
공공데이터포털
This table contains an all-sky soft gamma-ray source catalog based on IBIS observations performed during the first 1000 orbits of INTEGRAL. The database for the construction of the source list consists of all good-quality data available, from the launch of INTEGRAL in 2002, up to the end of 2010. This corresponds to ~ 110 Ms of scientific public observations, with a concentrated coverage on the Galactic Plane and extragalactic deep exposures. This new catalog includes 939 sources above a 4.5-sigma significance threshold detected in the 17-100 keV energy band, of which 120 sources represent previously undiscovered soft gamma-ray emitters. The source positions are determined, mean fluxes are provided in two main energy bands, and these are both reported together with the overall source exposure. Indicative levels of variability are provided, and outburst times and durations are given for transient sources. In the reference paper, a comparison is made with previous IBIS catalogs and catalogs from other similar missions. This database table, the Fifth IBIS/ISGRI source catalog, was ingested by the HEASARC in September 2016 based on the machine-readable version of Table 2 of the above-cited paper, which was obtained from the CDS website. It replaced the previous (fourth) version. This is a service provided by NASA HEASARC .
INTEGRAL IBIS AGN Catalog Update
공공데이터포털
In the most recent IBIS survey based on observations performed during the first 1000 orbits of INTEGRAL, there are listed 363 high-energy emitters firmly associated with AGN, 107 of which are reported here for the first time. The authors have used X-ray data to image the IBIS 90% error circle of all the AGN in the sample of 107, in order to obtain the correct X-ray counterparts, locate them with arcsecond accuracy and therefore pinpoint the correct optical counterparts. This procedure has led to the optical and spectral characterization of the entire sample. This new set consists of 34 broad line or type 1 AGN, 47 narrow line or type 2 AGN, 18 blazars and 8 sources of unknown class. These eight sources have been associated with AGN from their positional coincidence with 2MASX/Radio/X-ray sources. Seven high-energy emitters have also been included since they are considered to be good AGN candidates. Spectral analysis has been already performed on 55 objects and the results from the most recent and/or best statistical measurements have been collected. For the remaining 52 sources, the authors report the spectral analysis for the first time in this work. They have been able to obtain full X-ray coverage of the sample making use of data from Swift/XRT, XMM-Newton and NuSTAR. In addition to the spectral characterization of the entire sample, this analysis has enabled the authors to identify peculiar sources and by comparing different data sets, highlight flux variability in the 2-10 keV and 20-40 keV bands. In the reference paper, the authors present the X-ray and optical follow-up work on 107 new AGN recently detected by INTEGRAL. Fortunately, they have been able to obtain full X-ray coverage of the entire sample making use of data from the Swift/XRT, Newton-XMM, and NuSTAR archives or through Swift/XRT follow-up observations that they triggered. The HEASARC notes that this table of AGN newly detected by INTEGRAL and not included in the original INTEGRAL IBIS AGN Catalog (Malizia et al. 2012, MNRAS, 426, 1750, available at the HEASARC as the INTIBISAGN table) actually contains 108 AGN plus 8 candidate AGN, for a total of 116 objects, rather than the 107 plus 7 candidate AGN totalling 114 objects that are quoted in the abstract of the reference paper (and stated above). The reason for this discrepancy is not known to the HEASARC. This table was created by the HEASARC in November 2017 based on CDS Catalog J/MNRAS/460/19 files tablea1.dat and refs.dat.

There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019.* 2: This data set is from the Release 4 (3-year-average of 6-month-cadence maps) IBEX-Lo map data for the first three years 2009-2012 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU.* 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in numerical data form. Energy channels 1-8 have FWHM center-point energies at 0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled science from Release 10 are given in the following journal publication:* 4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146: 117...147; DOI 10.1007/s11214-009-9495-8* 5: https://link.springer.com/article/10.1007/s11214-009-9495-8* 6. The following codes are used to define dataset types:- cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs.- nocg = no Compton-Getting corrections- sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular.- noSP - no survival probability corrections have been applied to the data.- omni = data from all directions.- ram = data was collected when the spacecraft was ramming into the incoming ENAs.- antiram = data was collected when the spacecraft was moving away from the incoming ENAs.* 7.
