Observational insights on the formation scenarios of giant low surface brightness galaxies
Anna Saburova, Igor Chilingarian, Anastasia Kasparova +4
Giant low surface brightness galaxies (gLSBGs) with the disk radii of up to 130 kpc represent a challenge for currently accepted theories of galaxy formation and evolution, because…
The TELPERION Survey for Distant [O III] Clouds around Luminous and Hibernating AGN
William C. Keel, Alexei Moiseev, D. V. Kozlova +5
We present a narrowband [O III] imaging survey of 111 AGN hosts and 17 merging-galaxy systems, in search of distant extended emission-line regions (EELRs) around AGN (either extant…
Observation of a very massive galaxy cluster at z=0.76 in SRG/eROSITA all-sky survey
R. A. Burenin, I. F. Bikmaev, M. R. Gilfanov +16
The results of multiwavelength observations of the very massive galaxy cluster SRGe CL2305.2-2248 detected in X-rays during the first SRG/eROSITA all-sky survey are discussed. This…
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…
