Relativistic MHD simulations of merging and collapsing stars and effects on GRB transient
Agnieszka Janiuk, Gerardo Urrutia, Joseph Saji +1
Compact binary mergers and the collapse of massive stars can produce intense transients observable across high-energy wavelengths. Events such as gamma-ray bursts and kilonova emis…

Chemical Evolution and Kilonova Implications of Post-Merger Accretion Disk Winds
Agnieszka Janiuk, Joseph Saji, Gerardo Urrutia
Several gamma ray bursts have recently been associated with a kilonova emission. We study the mechanisms which could account for this effect, by means of radioactive decay of eleme…

Theoretical Modelling of Gamma-Ray Burst 090510
Joseph Saji, Agnieszka Janiuk, Maria Giovanna Dainotti +2
Gamma-ray bursts detected at high energies provide valuable insights into the emission mechanisms behind these still puzzling enigmatic events. In this study, we focus on GRB 09051…
