What we can learn about compact binary mergers from their kilonova signals?

Agnieszka Janiuk, Joseph Saji, Gerardo Urrutia

Compact binary mergers are sources of gravitational waves, and can be accompanied by electromagnetic signals. We discuss the possible features in the kilonova emissions which may h…

Following the jet interaction with a post-merger disk outflow

Gerardo Urrutia, Agnieszka Janiuk

Short GRBs are produced by relativistic jets arising from binary NS-NS or NS-BH mergers. Since the detection of the first unambiguous off-axis GRB 170817A, we learned that energy d…

Numerical GR MHD simulations of the post-merger system with a composition-dependent equation of state

Agnieszka Janiuk, Gerardo Urrutia

By means of HARM\_COOL\_EOS, which is our code for conservative relativistic magnetohydrodynamics, we developed a new scheme for the simulation of a system formed after compact bin…

Numerical simulations of polarisation in gamma-ray burst afterglows

Rogelio Medina Covarrubias, Fabio De Colle, Gerardo Urrutia +1

We compute the linear polarisation during the afterglow phase of gamma-ray bursts, for both on-axis and off-axis observers. We use numerical simulations of the deceleration of a re…

Gravitational Waves from the Propagation of Long Gamma-Ray Burst jets

Gerardo Urrutia, Fabio De Colle, Claudia Moreno +1

Gamma-ray bursts (GRBs) are produced during the propagation of ultra-relativistic jets. It is challenging to study the jet close to the central source, due to the high opacity of t…

Three-dimensional numerical simulations of structured GRB jets

Gerardo Urrutia, Fabio De Colle, Diego López-Cámara

After the detection of GRB 170817A, the first unambiguous off-axis gamma-ray burst (GRB), several studies tried to understand the structure of GRB jets. The initial jet structure (…
