A tidally disrupting dwarf galaxy in the halo of NGC 253
Elisa Toloba, David Sand, Kristine Spekkens +7
We report the discovery of Scl-MM-Dw2, a new dwarf galaxy at a projected separation of 50 kpc from NGC 253, as part of the PISCeS (Panoramic Imaging Survey of Centaurus and S…
The extended halo of Centaurus A: uncovering satellites, streams, and substructures
D. Crnojević, D. J. Sand, K. Spekkens +7
We present the widest-field resolved stellar map to date of the closest ( Mpc) massive elliptical galaxy NGC 5128 (Centaurus A; Cen A), extending out to a projected galac…
Evidence for the rapid formation of low mass early-type galaxies in dense environments
Yiqing Liu, Eric W. Peng, John Blakeslee +6
We explore the environmental dependence of star formation timescales in low mass galaxies using the [/Fe] abundance ratio as an evolutionary clock. We present integrated [/Fe…
Resolving the extended stellar halos of nearby galaxies: the wide-field PISCeS survey
D. Crnojević, D. J. Sand, N. Caldwell +6
In the wide-field Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS), we investigate the resolved stellar halos of two nearby galaxies (the elliptical Centaurus A and the…
The Most Massive Ultra-Compact Dwarf Galaxy in the Virgo Cluster
Chengze Liu, Eric W. Peng, Elisa Toloba +15
We report on the properties of the most massive ultra-compact dwarf galaxy (UCD) in the nearby Virgo Cluster of galaxies using imaging from the Next Generation Virgo Cluster Survey…
A Spectroscopic and Photometric Exploration of the C/M Ratio in the Disk of M31
Katherine M. Hamren, Constance M. Rockosi, Puragra Guhathakurta +12
We explore the ratio (C/M) of carbon-rich to oxygen-rich thermally pulsing asymptotic giant branch(TP-AGB) stars in the disk of M31 using a combination of moderate-resolution optic…
