I am a researcher working on fields like relativistic astrophysics and computational physics focusing mainly on compact objects like neutron stars and black holes. For this I use tools such as pen & paper and supercomputers.
Equation of state of the cold dense matter has remained mystery for decades. In this recent work, we set new constraints to the EoS parameters by using X-ray bursts that show signs of passive cooling.
What happens to the observed spectrum of neutrons stars when the atmosphere is full of heavy metals from the nuclear burning? On this article, published in A&A we test the effects by computing detailed atmosphere models.
Contains some doodlings I did in the world of hydrodynamics. At some point I became interested in how do fluids actually move so I build my own hydro code to find out.
In this work we show how the accretion modifies the cooling of X-ray bursts on top of neutron stars. This will then lead to (at least) two different classes of bursts, that differ considerably.
On this article, published in MNRAS, we show how the accretion can affect the NS mass and radius measurements that are done using the X-ray bursts.
A project I did of Cellular Automata. During my Christmas holidays I did some studies of how self-organizing criticality works. And for that one needs a proper Cellular Automaton code, of course!
