Effects of polar structure and moving ejecta on the dynamics of SGRB jets
Leonardo Garcia-Garcia, Diego Lopez-Camara, Davide Lazzati
At least some short gamma-ray bursts (SGRBs) originate from neutron star mergers, systems that release both a relativistic collimated jet and slower, wider ejecta. These jets evolv…

Three-dimensional simulations of accretion disks in pre-CE systems
Ana L. Juarez-Garcia, Orsola De Marco, Fabio De Colle +4
Before a binary system enters into a common envelope (CE) phase, accretion from the primary star onto the companion star through Roche Lobe overflow (RLOF) will lead to the formati…

A semi-analytical model for the propagation of a structured jet in a magnetized medium
Leonardo Garcia-Garcia, Diego Lopez-Camara, Davide Lazzati
The merger of two magnetized compact objects, such as neutron stars, forms a compact object which may launch a relativistic and collimated jet. Numerical simulations of the process…
