Abstract:
We present the results of an all-sky survey, performed with data
acquired 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, at energies above
100 keV. The catalogue of detected sources includes 132 objects. The
statistical sample detected on the time-averaged 100-150 keV map at a
significance above 5σ 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
catalogue also includes 15 persistent sources, which were registered
at significance 4σ≤S/N<5σ, where S/N is the
signal-to-noise ratio, but at the same time were firmly detected
(≥12σ) in the lower 17-60keV energy band. All registered
sources are known X-ray emitters, which means that the catalogue has
100 percent purity in this respect. Additionally, 29 catalogued
sources were detected significantly in different time slices of the
survey. In the context of the survey, we 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
150-300keV energy band, 25 sources have been detected with
S/N≥5σ, including seven AGNs, 13 LMXBs, three HMXBs and two
rotation-powered pulsars. Among LMXBs and HMXBs, we identified 12
black hole candidates (BHCs) and four neutron star (NS) binaries.
Description:
For the current hard X-ray survey, we utilized all publicly available
INTEGRAL data acquired by the IBIS telescope between 2002 December and
2014 January (spacecraft revolutions 26-1377). The survey also
contains private data from the M82 deep field (PI: Sazonov) and
scanning observations of the Galactic Centre (PI: Krivonos) and Puppis
region (PI: Tsygankov).

Note (1): The flux with S/N<2σ is shown as a 2σ upper limit.
If the detection significance does not exceed 10σ, it is shown in Flux2.
Note (2): Time interval, in units of spacecraft orbits, during which the
corresponding flux has been measured. If this column contains an empty value,
the flux has been determined from the whole time span of the survey.
INTEGRAL orbital revolutions can be roughly converted into the Modified
Julian Date (MJD) using the following empirical expression:
55551.61223380 + (ORBIT - 1000.0)/0.33404581.
Note (3): General astrophysical type of the object as follows:
LMXB = low- mass X-ray binary
HMXB = high-mass X-ray binary
AGN = active galactic nucleus
SNR = supernova remnant
PSR = isolated pulsar or PWN
SGR = soft gamma repeater
A type in blue with a question mark indicates that the specified type is not
firmly determined and should be confirmed.
Note (4): The spatial confusion with the source XXX is indicated as C{XXX},
where XXX is a name of the source has been mostly detected at energies below
100keV. The measured flux of sources being in spatial confusion should be
taken with the caution.
