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…
Broad line region echo from highly accreting intermediate-mass black hole candidate SDSS J144850.08+160803.1. The first probe of intra-night variability and reverberation mapping
Mariia Demianenko, Anton Afanasiev, Evgenii Rubtsov +8
Elusive intermediate-mass black holes (IMBHs) can be used as ``time-squeezing'' machines, enabling studies of AGN geometry via reverberation mapping on much shorter timescales than…
Dark matter content and dynamical masses of ultra-diffuse galaxies in the Coma cluster
Igor Chilingarian, Kirill Grishin, Anton V. Afanasiev +6
Ultra-diffuse galaxies (UDGs) are spatially extended, low surface brightness stellar systems with regular elliptical-like morphology found in large numbers in galaxy clusters and g…
Dwarf early-type galaxies in the Coma cluster: internal dynamics, stellar populations
Igor Chilingarian, Kirill Grishin, Anton V. Afanasiev +6
We present preliminary results from our spectroscopic survey of low-luminosity early-type galaxies in the Coma cluster conducted with the Binospec spectrograph at the 6.5~m MMT. Fr…
The galaxy mass-size relation in CARLA clusters and proto-clusters at 1.4 < z < 2.8: larger cluster galaxy sizes
Anton V. Afanasiev, Simona Mei, Hao Fu +12
(Abridged) We study the galaxy mass-size relation in CARLA spectroscopically confirmed clusters at , which span a total stellar mass $11.3<\mathrm{log}(M^c_*/M_{\odot})<…
Morphology-density Relation, Quenching, and Mergers in CARLA Clusters and Proto-Clusters at
Simona Mei, Nina A. Hatch, Stefania Amodeo +11
(Abridged) To understand if the morphology-density and passive-density relations are already established at z>1.5, we study galaxies in 16 confirmed clusters at from th…
KDG 64: a large dwarf spheroidal or a small ultradiffuse satellite of Messier 81
Anton V. Afanasiev, Igor V. Chilingarian, Kirill A. Grishin +5
Low-mass early-type galaxies, including dwarf spheroidals (dSph) and brighter dwarf ellipticals (dE), dominate the galaxy population in groups and clusters. Recently, an additional…
Transforming gas-rich low-mass disky galaxies into ultra-diffuse galaxies by ram pressure
Kirill Grishin, Igor Chilingarian, Anton Afanasiev +4
Faint extended elliptically-shaped ultra-diffuse galaxies and slightly brighter and more compact dwarf elliptical and lenticular stellar systems are common in galaxy clusters. Thei…
Evolutionary link between ultra-diffuse galaxies and dwarf early-type galaxies
Igor V. Chilingarian, Kirill A. Grishin, Anton V. Afanasiev +2
Spectroscopic studies of low-luminosity early-type galaxies are essential to understand their origin and evolution but remain challenging because of low surface brightness levels.…
Reconstructing star formation histories of recently formed ultra-diffuse galaxies
Kirill A. Grishin, Igor V. Chilingarian, Anton V. Afanasiev +1
Observational studies of ultra-diffuse galaxies (UDGs) represent a significant challenge because of their very low surface brightnesses. A feasible approach is to identify "future"…
Internal dynamics and stellar content of nine ultra-diffuse galaxies in the Coma cluster prove their evolutionary link with dwarf early-type galaxies
Igor Chilingarian, Anton Afanasiev, Kirill Grishin +2
Ultra-diffuse galaxies (UDGs) are spatially extended, low surface brightness stellar systems with regular elliptical-like morphology found in a wide range of environments. Studies…
Mass modelling of a superthin galaxy, FGC1540
Sushma Kurapati, Arunima Banerjee, Jayaram N. Chengalur +4
We present high resolution H{\sc i} 21cm Giant Meterwave Radio Telescope (GMRT) observations of the superthin galaxy FGC1540 with a spatial resolution of 10 8 and…
A 3.5-million Solar Masses Black Hole in the Centre of the Ultracompact Dwarf Galaxy Fornax UCD3
Anton V. Afanasiev, Igor V. Chilingarian, Steffen Mieske +16
The origin of ultracompact dwarfs (UCDs), a class of compact stellar systems discovered two decades ago, still remains a matter of debate. Recent discoveries of central supermassiv…
