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…
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…
Detectability of Gravitational-wave counterparts of EP-FXTs observed during the O4b LIGO-Virgo-KAGRA Observing Run
Ansh Chopra, Samuele Ronchini, Biswajit Banerjee +5
Fast X-ray transients (FXTs) detected by the Einstein Probe mission have emerged as a rapidly growing class of extragalactic transients, whose physical origin remains uncertain. Co…
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…
X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
Optical observations of candidate host galaxies of eight fast X-ray transients
Agnes P. C. van Hoof, Peter G. Jonker, Lieke Tommel +15
Fast X-ray transients (FXTs) are extragalactic flashes of X-rays with a typical duration of minutes to hours for which a variety of origins has been proposed and observed. To decip…
