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…

Discovery of a Supernova Following the Einstein Probe Transient EP250302a at z = 1.131

Brendan O'Connor, Malte Busmann, James Freeburn +7

We present a multi-wavelength analysis of the Einstein Probe (EP) fast X-ray transient (FXT) EP250302a located at redshift . Despite its luminous prompt X-ray emission, th…

The Deeper, Wider, Faster programme's first DECam optical data release

James Freeburn, Jeff Cooke, Anais Möller +17

The transient and variable optical sky is relatively poorly characterised on fast (1hr) timescales. With the Dark Energy Camera (DECam), the Deeper, Wider, Faster programme…
