The propagation of long GRB jets through and beyond its progenitor star
Gerardo Urrutia, Agnieszka Janiuk
Long gamma-ray bursts (lGRB) are produced by relativistic jets arising from the collapse of massive stars. Such progenitor environments present complex physical conditions that are…
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…
Numerical simulations of jet launching and breakout from collapsars
Gerardo Urrutia, Agnieszka Janiuk, Hector Olivares
Long Gamma-Ray Bursts (LGRBs) are often associated with the collapse of stripped-envelope massive stars. Powerful relativistic jets drill through the stellar envelope before the ga…
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…
