ASKAP Monitoring of the Rubin Deep Drilling Fields
Dougal Dobie, James Freeburn, Iris de Ruiter +5
In the past decade, time domain astronomy surveys across the multi-messenger spectrum have developed "alert streams" which circulate observational information in real-time to the w…
X-ray Through Radio Observations and Modeling of the Soft X-ray Flash GRB 250419A
Genevieve Schroeder, Anna Y. Q. Ho, Gavin P. Lamb +24
Soft X-ray flashes (XRFs) are predicted from a variety of hypothesized phenomena, including "dirty fireballs" (relativistic jets with significant baryon loading), and gamma-ray bur…
AT 2020afjz (TSS2020a): The First Fast Extragalactic Transient Discovered by TESS
Ryan Ridden-Harper, Hugh Roxburgh, Clarinda Montilla +13
We report the discovery of AT 2020afjz (TSS2020a): the first hour-scale extragalactic transient discovered in optical wavelengths whose complete evolution -- from explosion onset t…
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…
Electromagnetic Follow-up of the Sub-Solar Mass Gravitational Wave Candidate S251112cm: Kilonova Constraints and a Coincident IIb Supernova
Xander J. Hall, Tomas Ahumada, Julius Gassert +25
On November 12th, 2025 the LIGO--Virgo--KAGRA (LVK) collaboration reported gravitational waves (GWs) from a compact object merger candidate (S251112cm) with at least one sub-solar…
Prospects for GRB Afterglow Discovery with the Eric and Wendy Schmidt Observatory System
James Freeburn, Dougal Dobie, Akash Anumarlapudi +9
Two time domain surveys, recently funded as part of the Eric and Wendy Schmidt Observatory System; the Argus Array, in the optical, and the Deep Synoptic Array (DSA), in the radio,…
SN 2025adpq: A Type Ia supernova in a collisional ring formed during a major galaxy merger
Brendan O'Connor, Xander J. Hall, Tomas Cabrera +16
Galaxy mergers can both trigger star formation and rearrange where stars live, producing long-lived tidal structures and collisionally driven density waves (known as collisional ri…
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…
Multiwavelength Analysis of Six Luminous Fast Blue Optical Transients
Cassie Sevilla, Anna Y. Q. Ho, Nayana A. J. +43
We present multiwavelength observations and analysis of six luminous fast blue optical transients (LFBOTs) discovered in Zwicky Transient Facility (ZTF) survey data. We identified…
