SN2023ixf in Messier 101: the twilight years of the progenitor as seen by Pan-STARRS

Conor L. Ransome, V. Ashley Villar, Anna Tartaglia +28

The nearby type II supernova, SN2023ixf in M101 exhibits signatures of early-time interaction with circumstellar material in the first week post-explosion. This material may be the…

JWST Observations of the Extraordinary GRB 221009A Reveal an Ordinary Supernova Without Signs of -Process Enrichment in a Low-Metallicity Galaxy

Peter K. Blanchard, V. Ashley Villar, Ryan Chornock +18

Identifying the astrophysical sites of the -process, one of the primary mechanisms by which heavy elements are formed, is a key goal of modern astrophysics. The discovery of the…
