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 (…
Seven years of coordinated Chandra-NuSTAR observations of SN2014C unfold the extreme mass-loss history of its stellar progenitor
Daniel Brethauer, Raffaella Margutti, Danny Milisavljevic +13
We present the results from our seven-year long broad-band X-ray observing campaign of SN\,2014C with \emph{Chandra} and \emph{NuSTAR}. These coordinated observations represent the…
