X-ray flux -- mass relation for galaxy clusters
Natalia Lyskova, Eugene Churazov, Ildar Khabibullin +3
We use a subsample of co-detections of the ACT and MaDCoWS cluster catalogs to verify the predicted relation between the observed X-ray flux in the 0.5-2~keV band and the clu…
Further evidence of Quasiperiodic Eruptions in a tidal disruption event AT2019vcb by SRG/eROSITA
Sergei Bykov, Marat Gilfanov, Rashid Sunyaev +1
We report the discovery of a short, large amplitude X-ray flare from AT2019vcb (aka Tormund), a tidal disruption event at . The discovery is based on the data from the SRG…
X-ray Properties of the Luminous Quasar PG 1634+706 at z = 1.337 from SRG and XMM-Newton Data
Grigory Uskov, Sergey Sazonov, Marat Gilfanov +2
In the fall of 2019, during the in-flight calibration phase of the SRG observatory, the onboard eROSITA and Mikhail Pavlinsky ART-XC telescopes carried out a series of observations…
New Active Galactic Nuclei Detected by the ART-XC and eROSITA Telescopes during the First Five SRG All-Sky X-ray Surveys
Grigory Uskov, Sergey Sazonov, Igor Zaznobin +8
We present the results of our identification of 14 X-ray sources detected in the eastern Galactic sky ( ) in the 4-12 keV energy band on the combined map of the firs…
X-ray luminosity function of accreting neutron stars and black holes
K. A. Postnov, A. G. Kuranov, L. R. Yungelson +1
We model X-ray luminosity functions (XLF) of accreting neutron stars and black holes in erg/s range in star-forming galaxies and galaxies with the i…
Optical emission line spectra of symbiotic binaries
Jere Kuuttila, Marat Gilfanov
Symbiotic stars are long-period interacting binaries where the compact objects, most commonly a white dwarf, is embedded in the dense stellar wind of an evolved companion star. UV…
