Detecting Thin Stellar Streams in External Galaxies: Resolved Stars & Integrated Light
Sarah Pearson, Tjitske K. Starkenburg, Kathryn V. Johnston +2
The morphology of thin stellar streams can be used to test the nature of dark matter. It is therefore crucial to extend searches for globular cluster streams to other galaxies than…
The Masses of Supernova Remnant Progenitors in M83
Benjamin F. Williams, Tristan J. Hillis, William P. Blair +5
We determine the ages of the young, resolved stellar populations at the locations of 237 optically-identified supernova remnants in M83. These age distributions put constraints on…
The Progenitor Age and Mass of the Black-Hole-Formation Candidate N6946-BH1
Jeremiah W. Murphy, Rubab Khan, Benjamin Williams +3
The failed supernova N6946-BH1 likely formed a black hole (BH); we age-date the surrounding population and infer an age and initial mass for the progenitor of this BH formation can…
Reducing and Analyzing the PHAT Survey with the Cloud
Benjamin F. Williams, Knut Olsen, Rubab Khan +2
We discuss the technical challenges we faced and the techniques we used to overcome them when reducing the PHAT photometric data set on the Amazon Elastic Compute Cloud (EC2). We f…
SPIRITS: Uncovering Unusual Infrared Transients With Spitzer
Mansi M. Kasliwal, John Bally, Frank Masci +44
We present an ongoing, systematic search for extragalactic infrared transients, dubbed SPIRITS --- SPitzer InfraRed Intensive Transients Survey. In the first year, using Spitzer/IR…
Spitzer Photometry of ~1 Million Stars in M31 and 15 Other Galaxies
Rubab Khan
We present Spitzer IRAC m and MIPS m point-source catalogs for M and other mostly large, star forming galaxies at distances Mpc including M $5…
