The Masses of Supernova Remnant Progenitors in NGC 6946
Brad Koplitz, Jared Johnson, Benjamin F. Williams +5
We constrained the progenitor masses for 169 supernova remnants, 8 historically observed supernovae, and the black hole formation candidate in NGC 6946, finding that they are consi…
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…
Formation Timescales for High-Mass X-ray Binaries in M33
Kristen Garofali, Benjamin F. Williams, Tristan Hillis +4
We have identified 55 candidate high-mass X-ray binaries (HMXBs) in M33 using available archival {\it HST} and {\it Chandra} imaging to find blue stars associated with X-ray positi…
Isolating the young stellar population in the outer disk of NGC 300
Tristan J. Hillis, Benjamin F. Williams, Andrew E. Dolphin +2
The recent star formation history (SFH) in the outer disk of NGC 300 is presented through the analysis of color magnitude diagrams (CMDs). We analyze resolved stellar photometry by…
