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…

Ubiquitous Late Radio Emission from Tidal Disruption Events

Yvette Cendes, Edo Berger, Kate D. Alexander +9

We present radio observations of 23 optically discovered tidal disruption events (TDEs) on timescales of 500-3200 days post discovery. We detect nine new TDEs that did not have det…
