X-ray spectral scaling of black hole mass in quasi-periodic eruptive source RX J1301.9+2747
Lev Titarchuk, Elena Seifina, Vadim Arefiev +2
We present a spectral and timing analysis of X-ray emission from the actively accreting supermassive black hole (SMBH) in RX~J1301.9+2747 with prominent quasi-periodic eruptions (Q…
A wide-field X-ray search for the Geminga pulsar halo with SRG/ART-XC
Roman Krivonos, Silvia Manconi, Vadim Arefiev +8
Searches for the putative large-scale X-ray halo around the Geminga pulsar have been extensively performed using various narrow field-of-view X-ray telescopes. In this paper, we pr…
All-sky limits on Sterile Neutrino Galactic Dark Matter obtained with SRG/ART-XC after two years of operations
E. I. Zakharov, V. V. Barinov, R. A. Burenin +12
Dark matter sterile neutrinos radiatively decay in the Milky Way, which can be tested with searches for almost monochromatic photons in the X-ray cosmic spectrum. We analyse the da…
Search for pre-burst emission from binary neutron star mergers with Spectrum-Roentgen-Gamma
I. A. Mereminskiy, A. A. Lutovinov, K. A. Postnov +12
Close binary systems consisting of two neutron stars (BNS) emit gravitational waves, that allow them to merge on timescales shorter than Hubble time. It is widely believed, that NS…
Peculiar X-ray transient SRGA J043520.9+552226/AT2019wey discovered with SRG/ART-XC
I. A. Mereminskiy, A. V. Dodin, A. A. Lutovinov +24
Context: During the ongoing all-sky survey, the Mikhail Pavlinsky ART-XC telescope on board the SRG observatory should discover new X-ray sources, many of which can be transient. H…
SRG/ART-XC discovery of SRGA J204318.2+443815: towards the complete population of faint X-ray pulsars
A. A. Lutovinov, S. S. Tsygankov, I. A. Mereminskiy +19
We report a discovery of a new long-period X-ray pulsar SRGA J204318.2+443815/SRGe J204319.0+443820 in the Be binary system. The source was found in the second all-sky survey by th…
SRG/ART-XC all-sky X-ray survey: Catalog of sources detected during the first year
M. Pavlinsky, S. Sazonov, R. Burenin +20
We present a first catalog of sources detected by the Mikhail Pavlinsky ART-XC telescope on board the SRG observatory in the 4-12 keV energy band during its ongoing all-sky survey.…
Wide-field X-ray observations of the supernova remnant Puppis A with the SRG/ART-XC telescope
R. Krivonos, V. Arefiev, I. Lapshov +8
The Spectrum-Roentgen-Gamma (SRG) observatory is currently conducting its 4-year all-sky X-ray survey, started on December 12, 2019. The survey is periodically interrupted for tech…
The SRG X-ray orbital observatory, its telescopes and first scientific results
R. Sunyaev, V. Arefiev, V. Babyshkin +39
The orbital observatory Spectrum-Roentgen-Gamma (SRG), equipped with the grazing-incidence X-ray telescopes Mikhail Pavlinsky ART-XC and eROSITA, was launched by Roscosmos to the L…
The ART-XC telescope on board the SRG observatory
M. Pavlinsky, A. Tkachenko, V. Levin +59
ART-XC (Astronomical Roentgen Telescope - X-ray Concentrator) is the hard X-ray instrument with grazing incidence imaging optics on board the Spektr-Roentgen-Gamma (SRG) observator…
SRG/ART-XC and NuSTAR observations of the X-ray pulsar GRO J1008-57 in the lowest luminosity state
A. Lutovinov, S. Tsygankov, S. Molkov +6
We report results of the first broadband observation of the transient X-ray pulsar GRO J1008-57 performed in the quiescent state. Observations were conducted quasi-simultaneously w…
The eROSITA X-ray telescope on SRG
P. Predehl, R. Andritschke, V. Arefiev +90
eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the primary instrument on the Spectrum-Roentgen-Gamma (SRG) mission, which was successfully launched on July 1…
Observations of the X-ray pulsar LMC X-4 with NuSTAR: limit on the magnetic field and tomography of the system in the fluorescent iron line
A. E. Shtykovsky, A. A. Lutovinov, V. A. Arefiev +2
We present results of the spectral and timing analysis of the X-ray pulsar LMC X-4 with the NuSTAR observatory in the broad energy range 3-79 keV. Along with the detailed analysis…
On the Possibility of Improving the Orbits of Satellites Based on Observations of Isolated X-ray Pulsars
M. G. Revnivtsev, O. E. Gadzhily, A. A. Lutovinov +4
At present, there is a great worldwide interest in the development of technologies that allow information about the X-ray emission from pulsating cosmic sources to be used to obtai…
