HI Observations of Giant Low Surface Brightness Galaxies
Philip Lah, Nikhil Arora, Ivan Yu. Katko +5
Giant low surface brightness galaxies (gLSBs) are galaxies with extremely extended, faint, optical disks over 50 kpc in radius and have high total masses which can reach 10^12 sola…
MUSE Study of Two Giant Low-surface-brightness Galaxies with Compact Satellites
Anna S. Saburova, Damir Gasymov, Ivan S. Gerasimov +7
Giant low-surface-brightness disk galaxies (gLSBGs) are rare objects with disk radii up-to 160 kpc and dynamical masses of an order of up to 10 . Their very exist…
Stellar CoRGI in MaNGA: Stellar Counterrotating Galaxies Identified in the MaNGA Survey
Damir Gasymov, Ivan Yu. Katkov, Evgenii V. Rubtsov +8
Stellar counterrotating (CR) galaxies are systems hosting two large-scale stellar components rotating in opposite directions -- a main, preexisting galaxy body with an older stella…
Optical Emission-Line Properties of eROSITA-selected SDSS-V Galaxies
Nadiia G. Pulatova, Evgenii Rubtsov, Igor V. Chilingarian +21
We present and discuss optical emission line properties obtained from the analysis of Sloan Digital Sky Survey (SDSS) spectra for an X-ray selected sample of 3684 galaxies (0.002 <…
A group of merging galaxies falling onto Abell 2142
Aashiya Anitha Shaji, Anaëlle Hallé, Damir Gasymov +3
Galaxy clusters produce a very hostile environment to galaxies, whose gas gets stripped by ram-pressure, suffer galaxy interactions and witness quenching of their star formation. C…
Optical spectroscopy of host-galaxies of intermediate mass black holes: evolution of central black holes
V. Goradzhanov, I. Chilingarian, M. Demianenko +6
Intermediate-mass black holes (IMBHs) with masses below () are pivotal in understanding the origin and growth mechanisms of supermassive black holes (SMBHs…
