Gamma-ray burst progenitors revisited
Andrew J. Levan, Jillian C. Rastinejad, Helena-Margaret S. Grabham +11
The paper examines nearby long-duration gamma-ray bursts that lack supernova signatures, finding that many may originate from compact object mergers rather than massive stars, and…
Compact Objects Merging with Stars as an Origin of Ultra-Long Gamma-Ray Bursts and Luminous Fast Blue Optical Transients
V. Ashley Villar, Anya E. Nugent, Eric Burns +4
Ultra-long gamma-ray bursts (ULGRBs) and luminous fast blue optical transients (LFBOTs) are two rare classes of engine-driven transients whose physical connection remains unknown.…
The Environments of Luminous Fast Blue Optical Transients: Evidence for a Compact Object and Wolf-Rayet Star Merger Origin
Anya E. Nugent, V. Ashley Villar, Brian D. Metzger +5
We present a comprehensive analysis of the host galaxies of 11 luminous fast blue optical transients (LFBOTs). We model new and archival host photometry and spectroscopy with Prosp…
Can COSI detect -ray lines from rare isotopes produced in the astrophysical intermediate neutron-capture process?
Falk Herwig, Pavel Denissenkov, Eric Burns
We investigate the nuclear -ray line emission from rare isotopes produced in the astrophysical intermediate neutron-capture process ( process) and assess the prospects of obs…
EP250827b/SN 2025wkm: An X-ray Flash-Supernova Powered by a Central Engine and Circumstellar Interaction
Gokul P. Srinivasaragavan, Dongyue Li, Xander J. Hall +100
We present the discovery of EP250827b/SN 2025wkm, an X-ray Flash (XRF) discovered by the Einstein Probe (EP), accompanied by a broad-line Type Ic supernova (SN Ic-BL) at $z = 0.119…
Label Propagation for Identifying Gamma-Ray Burst Progenitors from Prompt Emission
Skye Strain, Nicoló Cibrario, Michela Negro +1
Gamma-ray bursts (GRBs) are the most energetic bursts of light in our universe, and rapid progenitor association of these events can lead to targeted and optimized follow-up observ…
