Highly Variable Active Galactic Nuclei in the SRG/eROSITA All-Sky Survey: I. Constructing Sample and Catalog of Sources Detected in Low State
Pavel Medvedev, Marat Gilfanov, Sergey Sazonov +2
We present the results of our search for highly variable active galactic nuclei (AGNs) the X-ray flux from which changed by more than an order of magnitude during the SRG/eROSITA a…
SRGe2149+6736 -- the new candidate to AM~Her type variables discovered by eROSITA telescope on "Spectrum--Roentgen--Gamma" orbital observatory
I. F. Bikmaev, A. I. Kolbin, V. V. Shimansky +18
We present the results of the optical identification, classification, as well as analysis of photometric and spectral observations of the X-ray transient SRGe2149+6736 detected by…
Is the X-ray bright z = 5.5 quasar SRGE J170245.3+130104 a blazar?
Tao An, Ailing Wang, Yuanqi Liu +11
Jets may have contributed to promoting the growth of seed black holes in the early Universe, and thus observations of radio-loud high-redshift quasars are crucial to understanding…
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…
New Active Galactic Nuclei Detected by the ART-XC and eROSITA Telescopes Onboard the SRG Observatory during an All-Sky X-ray Survey
Grigory Uskov, Igor Zaznobin, Sergey Sazonov +9
We present the results of our identification of 17 X-ray sources detected in the 4-12 keV energy range by the Mikhail Pavlinsky ART-XC telescope during the first year of the SRG al…
The X-ray and Radio Loud Fast Blue Optical Transient AT2020mrf: Implications for an Emerging Class of Engine-Driven Massive Star Explosions
Yuhan Yao, Anna Y. Q. Ho, Pavel Medvedev +9
We present AT2020mrf (SRGe J154754.2443907), an extra-galactic () fast blue optical transient (FBOT) with a rise time of days and a peak luminosit…
