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…
