Considering the Single and Binary Origins of the Type IIP SN 2017eaw
K. Azalee Bostroem, Emmanouil Zapartas, Brad Koplitz +3
Current population synthesis modeling suggests that 30-50% of Type II supernovae originate from binary progenitors, however, the identification of a binary progenitor is challengin…
Constraining Circumgalactic Turbulence with QSO Absorption-line Measurements
Brad Koplitz, Edward Buie, Evan Scannapieco
Our knowledge of the circumgalactic medium (CGM) is mostly based on quasar absorption-line measurements. These have uncovered a multiphase medium that is likely highly turbulent, b…
The Masses of Supernova Remnant Progenitors in M33
Brad Koplitz, Jared Johnson, Benjamin F. Williams +7
Using resolved optical stellar photometry from the Panchromatic Hubble Andromeda Treasury Triangulum Extended Region (PHATTER) survey, we measured the star formation history (SFH)…
A Multiwavelength Classification and Study of Red Supergiant Candidates in NGC 6946
Jared R. Johnson, Brad Koplitz, Benjamin F. Williams +3
We have combined resolved stellar photometry from Hubble Space Telescope (\emph{HST}), \emph{Spitzer}, and \emph{Gaia} to identify red supergiant (RSG) candidates in NGC~6946, base…
