Mapping the Tidal Disruption of the Hercules Dwarf: A Wide-Field DECam Imaging Search for RR Lyrae Stars
Christopher Garling, Beth Willman, David J. Sand +10
We investigate the hypothesized tidal disruption of the Hercules ultra-faint dwarf galaxy (UFD). Previous tidal disruption studies of the Hercules UFD have been hindered by the hig…
Deep Subaru Hyper Suprime-Cam observations of Milky Way satellites Columba I and Triangulum II
Jeffrey L. Carlin, David J. Sand, Ricardo R. Munoz +9
We present deep, wide-field Subaru Hyper Suprime-Cam photometry of two recently discovered satellites of the Milky Way (MW): Columba I and Triangulum II. The color magnitude diagra…
Science-Driven Optimization of the LSST Observing Strategy
LSST Science Collaboration, Phil Marshall, Timo Anguita +102
The Large Synoptic Survey Telescope is designed to provide an unprecedented optical imaging dataset that will support investigations of our Solar System, Galaxy and Universe, acros…
The faint globular cluster in the dwarf galaxy Andromeda I
Nelson Caldwell, Jay Strader, David J. Sand +2
Observations of globular clusters in dwarf galaxies can be used to study a variety of topics, including the structure of dark matter halos and the history of vigorous star formatio…
Quantifying the Origin and Distribution of Intracluster Light in a Fornax-like Cluster
Kathryn A. Harris, Victor P. Debattista, Fabio Governato +9
Using a cosmological -body simulation, we investigate the origin and distribution of stars in the intracluster light (ICL) of a Fornax-like cluster. In a dark matter only simula…
The predicted luminous satellite populations around SMC and LMC-mass galaxies - A missing satellite problem around the LMC?
Gregory A. Dooley, Annika H. G. Peter, Jeffrey L. Carlin +3
Recent discovery of many dwarf satellite galaxies in the direction of the Small and Large Magellanic Clouds (SMC and LMC) provokes questions of their origins, and what they can rev…
