Gamma-ray bursts

Gamma-ray bursts (GRBs) are the most energetic events in the Universe, releasing a prodigious amounts of energy in a matter of less than few tens of seconds. After four decades of research, we're finally beginning to understand the physics of relativistic outflows powered by the central engine in GRBs. However, the details of the mechanism giving rise to the prompt gamma-ray emission are still not clear.

We have developed a cogent explanation for the prompt emission mechanism in a series of articles:

Neutron stars

Neutron stars (NSs) are one of the most interesting objects in the Universe, exhibiting a number of interesting phenomena.

I've worked on some very interesting problems:
