A JWST redshift for the host galaxy of EP250207b of z=3.2: a collapsar origin is viable
Agnes P. C. van Hoof, Peter G. Jonker, Andrew J. Levan +27
We present James Webb Space Telescope (JWST) and Hubble Space Telescope (HST) observations of the field of the fast X-ray transient (FXT) detected by Einstein Probe, EP250207b, to…
Multi-wavelength Constraints on the Transient EP250905a
J. Quirola-Vasquez, P. G. Jonker, A. Levan +30
Fast X-ray transients (FXTs) are a diverse class of high-energy suggested origins, ranging from stellar explosions to compact object mergers. The Einstein Probe (EP) satellite disc…
The properties of tidal disruption event infrared counterparts produced by dust rings and inference of the observing angle
Rob A. J. Eyles-Ferris
A substantial fraction of tidal disruption events (TDEs), resulting from a black holes's disruption and accretion of a star, exhibit infrared (IR) counterparts thought to arise fro…
Failed jet breakout in the metal-poor broad-lined type Ic supernova 2026gzf
Antonio Martin-Carrillo, Christina C. Thöne, James K. Leung +103
A long-standing question in the death of massive stars is the role of relativistic jets. While many gamma-ray bursts and some fast X-ray transients seem to be associated with broad…
Probing a new subclass of llGRB-SN transients: Insights from EP250304a and its associated supernova
L. Cotter, A. Martin-Carrillo, R. A. J. Eyles-Ferris +60
With the advent of the Einstein Probe (EP) mission, we are entering a new era in the study of gamma-ray bursts (GRBs), enabling the detection of faint, low-luminosity transients th…
ENGRAVE follow-up of a type IIb supernova spatially coincident with the sub-threshold gravitational wave trigger S250818k
K. Ackley, M. T. Botticella, A. Boye +54
The candidate gravitational wave (GW) event S250818k was one of only three non-retracted LIGO-Virgo-KAGRA public alerts issued during the fourth observing run of the network (O4) w…
