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…
eUDS: The SRG/eROSITA X-ray Survey of the UKIDSS Ultra Deep Survey Field. Catalogue of Sources
R. Krivonos, M. Gilfanov, P. Medvedev +2
The eROSITA X-ray telescope on board the Spectrum-Roentgen-Gamma (SRG) spacecraft observed the field of the UKIDSS Ultra-Deep Survey (UDS) in August-September 2019, during its flig…
Optical identification and follow-up observations of SRGA J213151.5+491400 -- a new magnetic cataclysmic variable discovered with SRG Observatory
Ş. Balman, I. Khamitov, A. Kolbin +21
We report results of optical identification and multi-wavelength study of a new polar-type magnetic cataclysmic variable (MCV), SRGA J213151.5+491400, discovered by Spectrum Roentg…
A Joint SRG/eROSITA + ZTF Search: Discovery of a 97-min Period Eclipsing Cataclysmic Variable with Evidence of a Brown Dwarf Secondary
Ilkham Galiullin, Antonio C. Rodriguez, Shrinivas R. Kulkarni +24
Cataclysmic variables (CVs) that have evolved past the period minimum during their lifetimes are predicted to be systems with a brown dwarf donor. While population synthesis models…
