Relativistic jets and the Collapsar model
Propagation of relativistic jets in an extarnal media is a key process in high energy astrophysics. We constructed a self consistent analytic model of that propagation, that account for the collimation shocks....   read more...​

Relativistic and Newtonian shock breakouts
The light from the breakout of a shock through the stellar surface is the first electromagnetic signal from any stellar explosion. This light carries a wealth of information on the progenitor and on the explosion itself ...      read more...​

The structure of colissionless shocks 
Collisionless shocks are ubiquitous in astrophysics where supersonic motions in tenuous plasma is common. These shocks take place on all scales, ranging from the interplanetary space...        read more...​

Short-Hard Gamma-Ray Bursts
Gamma-ray bursts (GRBs) are the brightest electromagnetic sources in the Universe. Within seconds these ultra-relativistic sources release more energy than our sun will over its entire life time. Two types of GRBs are observed: short-duration GRBs and...            read more...

My current main field of interest is high-energy astrophysics including phenomena such as gamma-ray bursts, supernovae and soft gamma-repeaters and physical processes such as colissionless and radiation mediated shocks, shock breakouts, particle acceleration, relativistic hydrodynamics and radiative transfer. In the past I also studied topics in complex systems and nonlinear dynamics. Below you can find a description of some of the topics that I studied over the years.
