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…
HectoMAP: The Complete Redshift Survey (Data Release 2)
Jubee Sohn, Margaret J. Geller, Ho Seong Hwang +3
HectoMAP is a dense redshift survey of 95,403 galaxies based primarily on MMT spectroscopy with a median redshift . The survey covers 54.64 square degrees in a 1.5$^\cir…
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…
The Tierras Observatory: An ultra-precise photometer to characterize nearby terrestrial exoplanets
Juliana García-Mejía, David Charbonneau, Daniel Fabricant +4
We report on the status of the Tierras Observatory, a refurbished 1.3-m ultra-precise fully-automated photometer located at the F. L. Whipple Observatory atop Mt. Hopkins, Arizona.…
