First tidal disruption events discovered by SRG/eROSITA: X-ray/optical properties and X-ray luminosity function at z<0.6
S. Sazonov, M. Gilfanov, P. Medvedev +22
We present the first sample of tidal disruption events (TDEs) discovered during the SRG all-sky survey. These 13 events were selected among X-ray transients detected in the 0<l<180…
Probabilistic photo-z machine learning models for X-ray sky surveys
Viktor Borisov, Alex Meshcheryakov, Sergey Gerasimov +1
Accurate photo-z measurements are important to construct a large-scale structure map of X-ray Universe in the ongoing SRG/eROSITA All-Sky Survey. We present machine learning Random…
Morphological classification of astronomical images with limited labelling
Andrey Soroka, Alex Meshcheryakov, Sergey Gerasimov
The task of morphological classification is complex for simple parameterization, but important for research in the galaxy evolution field. Future galaxy surveys (e.g. EUCLID) will…
Discovery of the most X-ray luminous quasar SRGE J170245.3+130104 at redshift z
G. A. Khorunzhev, A. V. Meshcheryakov, P. S. Medvedev +10
SRGE J170245.3+130104 was discovered by the eROSITA telescope aboard the SRG space observatory on March 13-15, 2020 during the first half-year scan of its all-sky X-ray survey. The…
