The volume density of giant low surface brightness galaxies
Anna S. Saburova, Igor V. Chilingarian, Andrea Kulier +5
Rare giant low surface brightness galaxies (gLSBGs) act as a stress test for the current galaxy formation paradigm. To answer the question `How rare are they?' we estimate their vo…
Optical Variability of "Light-weight" Supermassive Black Holes at a Few Percent Level from ZTF Forced-Photometry Light Curves
Mariia Demianenko, Kirill Grishin, Victoria Toptun +4
Large time-domain surveys provide a unique opportunity to detect and explore variability of millions of sources on timescales from days to years. Broadband photometric variability…
Optical spectroscopic observations of intermediate-mass black holes and their host galaxies: the relation
Vladimir Goradzhanov, Igor Chilingaryan, Ivan Katkov +4
Intermediate-mass black holes (IMBHs; ) in galaxy centers are cruciel for painting a coherent picture of the formation and growth of supermassive black…
Confirmation of intermediate-mass black holes candidates with X-ray observations
Victoria Toptun, Igor Chilingarian, Kirill Grishin +5
The origin of supermassive black holes (SMBH) in galaxy centers still remains uncertain. There are two possible ways of their formation - from massive () and…
