GRB 220706A: a gamma-ray burst with a month-long engine and a luminous supernova

Benjamin P. Gompertz, Nusrin Habeeb, Dheeraj R. Pasham +30

While the progenitors of many long gamma-ray bursts (GRBs) are well established as the core collapse of very massive, envelope-stripped, rapidly-rotating stars, it has been suggest…

A Proliferated Space Architecture for Time-Domain Astrophysics

Daniel Kocevski, Eric Burns, Thomas Barclay +58

Time-Domain and Multi-Messenger Astrophysics (TDAMM) is entering a discovery-rich but follow-up-limited era, creating an urgent need for responsive, multiwavelength space-based cap…

The Role of Stellar Spin in Repeating Partial Tidal Disruption Events

Ananya Bandopadhyay, Benjamin Amend, Eric R. Coughlin +3

The repeated tidal stripping of a star by a supermassive black hole, known as a repeating partial tidal disruption event (rpTDE), can give rise to a transient that rebrightens mont…

EP260321a/SN 2026gzf: The Faintest Shock Breakout Associated with a Broad-Lined Supernova

Brendan O'Connor, Xander J. Hall, Malte Busmann +33

The explosion of a star is first marked by the shock wave breaking out of the stellar surface, producing a burst of ultraviolet and X-ray radiation. These events are observationall…

Late-time JWST/NIRCam Observations of the Extremely Long-duration GRB 250702B/EP 250702a and Its Host Galaxy

Huei Sears, Jean J. Somalwar, Ryan Chornock +22

We present JWST/NIRCam observations of the extremely long-duration gamma-ray burst (GRB) 250702B taken at ~ 95 days post-GRB (observer frame). The observations of the host galaxy r…
