A Multi-Wavelength View of the First Type Ic-BL Supernova with an Einstein Probe X-ray Shock Breakout
Jillian C. Rastinejad, Gokul Srinivasaragavan, Nikhil Sarin +36
The paper reports multi-wavelength observations of the nearby fast X‑ray transient EP260321a, identified as the shock‑breakout of a broad‑line Type Ic supernova (SN2026gzf), and us…
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.…
Beta-Particle Transport and Thermalization in Kilonova Ejecta with Detailed Atomic Microphysics
Zachary L. Andalman, Christopher L. Fryer, Christopher J. Fontes +2
When two neutron stars collide, they eject material containing heavy nuclei formed by the rapid neutron capture process (-process). As these nuclei decay, they power a bright op…
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…
A comparison of three neodymium atomic data sets for kilonova modeling
Christopher J. Fontes, Nicholas Vieira, Chris L. Fryer +4
We examine the impact of input neodymium (Nd) atomic data on the light curves and spectra of kilonovae, probing the sensitivity of kilonova observables to the atomic physics of thi…
GRB 250702B: Discovery of a Gamma-Ray Burst from a Black Hole Falling into a Star
Eliza Neights, Eric Burns, Chris L. Fryer +52
Gamma-ray bursts are the most luminous electromagnetic events in the universe. Their prompt gamma-ray emission has typical durations between a fraction of a second and several minu…
