The Ep-Liso correlation: A new diagnostic tool for kilonova transients

Ruben Farinelli, Fabrizio Cogato, Mattia Bulla +10

The AT2017gfo kilonova transient remains a unique multi-messenger event thanks to its proximity (z=0.00987) and the possibility to investigate time-resolved spectra, providing evid…

The soft X-ray transient EP241021a: A cosmic explosion with a complex off-axis jet and cocoon from a massive progenitor

Giulia Gianfagna, Luigi Piro, Gabriele Bruni +22

X-ray flashes (XRFs) are fast X-ray transients thought to be softer analogs of gamma-ray bursts (GRBs). With its soft X-ray sensitivity, the Einstein Probe (EP) provides a unique o…

Deciphering the Physical Origin of GRB 240825A: A Long GRB Lacking a Bright Supernova

Rahul Gupta, Judith L. Racusin, R. Sanchez-Ramirez +52

We present a comprehensive multiwavelength analysis of GRB 240825A, a bright gamma-ray burst (GRB) detected by Fermi and Swift, with a prompt duration ( ~ 4 sec in 50-3…

EP 250108a/SN 2025kg: Observations of the most nearby Broad-Line Type Ic Supernova following an Einstein Probe Fast X-ray Transient

J. C. Rastinejad, A. J. Levan, P. G. Jonker +66

With a small sample of fast X-ray transients (FXTs) with multi-wavelength counterparts discovered to date, the progenitors of FXTs and their connections to gamma-ray bursts (GRBs)…

Euclid Quick Data Release (Q1). The active galaxies of Euclid

Euclid Collaboration, T. Matamoro Zatarain, S. Fotopoulou +355

We present a catalogue of candidate active galactic nuclei (AGN) in the Quick Release (Q1) fields. For each source we collect multi-wavelength photometry and spec…

GRB 211024B: an ultra-long GRB powered by magnetar

Shao-Yu Fu, Dong Xu, Wei-Hua Lei +15

Ultra-long gamma-ray bursts (ULGRBs) are characterized by exceptionally long-duration central engine activities, with characteristic timescales exceeding 1000 seconds. We present g…
