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…
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…
An energetic dirty fireball detected in soft X-rays
C. -Y. Dai, J. Quirola-Vásquez, Y. -H. Wang +76
The collapse of massive stars drives explosions that power relativistic fireballs. If only a small amount of matter is entrained, such clean fireballs can expand with Lorentz facto…
JWST and HST observations of the host galaxy and supernova, SN 2024aihh in EP240801a at z=1.67
Agnes P. C. van Hoof, Andrew J. Levan, Peter G. Jonker +15
We present James Webb Space Telescope (JWST) and Hubble Space Telescope (HST) observations of the counterpart of EP240801a, at z=1.67, the first fast X-ray transient (FXT) identifi…
Unveiling the nature of the Einstein Probe transient EP 241021a
J. Quirola-Vásquez, P. G. Jonker, A. J. Levan +23
We present a multi-wavelength analysis of the fast X-ray transient EP 241021a, discovered by the Wide-field X-ray Telescope aboard the \emph{Einstein Probe} satellite on 2024 Octob…
