Dust processing in elliptical galaxies
Hiroyuki Hirashita, Takaya Nozawa, Alexa Villaume +1
We reconsider the origin and processing of dust in elliptical galaxies. We theoretically formulate the evolution of grain size distribution, taking into account dust supply from as…
Hiding in plain sight: record-breaking compact stellar systems in the Sloan Digital Sky Survey
Michael A. Sandoval, Richard P. Vo, Aaron J. Romanowsky +10
Motivated by the recent, serendipitous discovery of the densest known galaxy, M60-UCD1, we present two initial findings from a follow-up search, using the Sloan Digital Sky Survey,…
Spectroscopic Confirmation of the Existence of Large, Diffuse Galaxies in the Coma Cluster
Pieter van Dokkum, Aaron Romanowsky, Roberto Abraham +6
We recently identified a population of low surface brightness objects in the field of the z=0.023 Coma cluster, using the Dragonfly Telephoto Array. Here we present Keck spectrosco…
Circumstellar Dust Around AGB Stars and Implications for Infrared Emission from Galaxies
Alexa Villaume, Charlie Conroy, Benjamin Johnson
Stellar population synthesis (SPS) models are used to infer many galactic properties including star formation histories, metallicities, and stellar and dust masses. However, most S…
A SLUGGS and Gemini/GMOS combined study of the elliptical galaxy M60: wide-field photometry and kinematics of the globular cluster system
Vincenzo Pota, Jean P. Brodie, Terry Bridges +20
We present new wide-field photometry and spectroscopy of the globular clusters (GCs) around NGC 4649 (M60), the third brightest galaxy in the Virgo cluster. Imaging of NGC 4649 was…
