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…
Measurement of the supermassive black hole masses in two active galactic nuclei by the photometric reverberation mapping method
E. A. Malygin, E. S. Shablovinskaya, R. I. Uklein +1
We present the results of long-term photometric monitoring of two active galactic nuclei, 2MASX J08535955+7700543 (z 0.106) and VII Zw 244 (z 0.131), being investigat…
Stokes-polarimeter for 1-meter telescope
Victor Afanasiev, Elena Shablovinskaya, Roman Uklein +1
We present the "StoP" photometer-polarimeter (Stokes-polarimeter) used for observations with the 1-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sc…
Observational insights on the origin of giant low surface brightness galaxies
Anna Saburova, Igor Chilingarian, Anastasia Kasparova +4
Giant low surface brightness galaxies (gLSBGs) with dynamically cold stellar discs reaching the radius of 130 kpc challenge currently considered galaxy formation mechanisms. We ana…
Unveiling the origin of giant low surface brightness discs: results of the long-slit spectral observations
Anna S. Saburova, Igor V. Chilingarian, Anastasia V. Kasparova +3
Giant low surface brightness galaxies (gLSB) with radii of discs as large as 130 kpc challenge galaxy formation scenarios and it is still not well understood how they form and evol…
Medium-band photometric reverberation mapping of AGNs at . Techniques and sample
Eugene Malygin, Roman Uklein, Elena Shablovinskaya +2
The most popular method of the broad-line region size estimation in active galactic nuclei (AGN) is the reverberation mapping based on measuring the time delay between the continuu…
