First Results from the LSST Shadow Survey: The Restless Luminous Blue Variable AT2017des in the Virgo-Cluster Galaxy, NGC4532
Conor L. Ransome, Bhagya M. Subrayan, David J. Sand +66
The Legacy Survey of Space and Time (LSST) will start in late-summer 2026, revolutionizing transient astronomy. Here, we present the Dark Energy Camera (DECam) Shadow Survey, which…
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…
Early Multiwavelength Observations of AT 2026fgk: The Luminous Afterglow to Sub-luminous GRB 260310A, Identified Independently of a Gamma-ray Trigger
K. -R. Hinds, A. Y. Q. Ho, Y. Wagh +103
The origins of sub-luminous (\,erg\,s) gamma-ray bursts (GRBs) associated with broad-lined Type~Ic supernovae (Ic-BL SNe) are poorly u…
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,…
Insights from GRBs for optical follow-up of gravitational wave counterparts
Kruthi Krishna, Andrew Levan, Samaya Nissanke +9
Identifying the electromagnetic counterparts to gravitational wave sources is vital to enabling the myriad of investigations possible with multimessenger astronomy. However, locati…
SN 2024iss: A Multi-Wavelength Exposé of a Type IIb Supernova with an Early-Time Ultraviolet Spectrum and Shock Breakout Constraints
Rujula Yete, Wynn Jacobson-Galan, Ferdinand Ferdinand +49
We present multi-wavelength observations and a comprehensive analysis of the nearby (D14 Mpc) Type IIb supernova (SN IIb) 2024iss. Observations of SN2024iss include an early…
A GPU-Accelerated Transient Detection Pipeline for DECam Time-Domain Surveys
Lei Hu, Tomás Cabrera, Antonella Palmese +8
We present a GPU-accelerated transient detection pipeline developed for time-domain surveys with the Dark Energy Camera (DECam). It enables real-time-capable image processing, inco…
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…
Detecting electromagnetic counterparts to LIGO/Virgo/KAGRA gravitational wave events with DECam: Neutron Star Mergers
Keerthi Kunnumkai, Antonella Palmese, Amanda M Farah +7
With GW170817 being the only multimessenger gravitational wave (GW) event with an associated kilonova detected so far, there exists a pressing need for realistic estimation of the…
