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…
Early Spectroscopy and Dense Circumstellar Medium Interaction in SN 2023ixf
K. Azalee Bostroem, Jeniveve Pearson, Manisha Shrestha +53
We present the optical spectroscopic evolution of SN~2023ixf seen in sub-night cadence spectra from 1.18 to 14 days after explosion. We identify high-ionization emission features,…
SN2017egm: A Helium-rich Superluminous Supernova with Multiple Bumps in the Light Curves
Jiazheng Zhu, Ning Jiang, Subo Dong +28
When discovered, SN~2017egm was the closest (redshift ) hydrogen-poor superluminous supernova (SLSN-I) and a rare case that exploded in a massive and metal-rich galaxy. Thu…
A long life of excess: The interacting transient SN 2017hcc
S. Moran, M. Fraser, R. Kotak +29
In this study we present the results of a five-year follow-up campaign of the long-lived type IIn supernova SN 2017hcc, found in a spiral dwarf host of near-solar metallicity. The…
Observations of the luminous red nova AT 2021biy in the nearby galaxy NGC 4631
Y. -Z. Cai, A. Pastorello, M. Fraser +73
We present an observational study of the luminous red nova (LRN) AT\,2021biy in the nearby galaxy NGC\,4631. The field of the object was routinely imaged during the pre-eruptive st…
