AT2025ulz and S250818k: Deep X-ray and radio limits on off-axis afterglow emission and prospects for future discovery

Brendan O'Connor, Roberto Ricci, Eleonora Troja +15

The first joint electromagentic (EM) and gravitational wave (GW) detection, known as GW170817, marked a critical juncture in our collective understanding of compact object mergers.…

The GROND GRB sample: II. Fireball parameters for four GRB afterglows

Karla Varela, Jochen Greiner, Patricia Schady +1

Afterglows of GRBs are, in general, well described by the fireball model. Yet, deducing the full set of model parameters from observations without prior assumptions has been possib…

A lanthanide-rich kilonova in the aftermath of a long gamma-ray burst

Yu-Han Yang, Eleonora Troja, Brendan O'Connor +24

Observationally, Kilonovae are astrophysical transients powered by the radioactive decay of nuclei heavier than iron, synthesized in the merger of two compact objects. Over the fir…

Katu: a fast open-source full lepto-hadronic kinetic code suitable for Bayesian inference modelling of blazars

Bruno Jiménez Fernández, Hendrik van Eerten

In the modelling of blazars and other radiating plasma flows, correctly evolving in time a series of kinetic equation coupled for different particle species is a computationally ch…

A thousand days after the merger: continued X-ray emission from GW170817

E. Troja, H. van Eerten, B. Zhang +7

Recent observations with the Chandra X-ray telescope continue to detect X-ray emission from the transient GW170817. In a total exposure of 96.6 ks, performed between March 9 and Ma…

Gamma-Ray Burst Afterglows In The Multi-Messenger Era: Numerical Models and Closure Relations

Geoffrey Ryan, Hendrik van Eerten, Luigi Piro +1

Gamma-ray bursts (GRBs) associated with gravitational wave events are, and will likely continue to be, viewed at a larger inclination than GRBs without gravitational wave detection…
