I am a PostDoc at the
Universiteit van Amsterdam. I'm mainly focusing my studies on
timing analysis of low mass X-ray binaries. Accretion onto neutron
stars and black holes in such systems provide an excellent laboratory
to study the physics of dense matter and strong gravity. Therefore,
with the analysis I perform, I aim to understand the
observational similarities and differences found among different type
of sources in order to gain a better understanding of the
processes that occur around these amazing objects.
Particularly, I am interested
in (a) the study of the similarities and differences found in the
behavior of the noise components at low frequencies (<100 Hz) in
both black hole and neutron star systems, (b) state transitions which
occur very fast and are difficult to observe, (c) a special
kind
of milihertz quasi-periodic oscillations which are thought to be the
observational signature of marginally stable nuclear burning on the
neutron star, (d) X-ray bursts, which are sudden and powerful
explosions on the surface of the neutron star, (e) long term
variability observed in many sources which are generally associated
with the orbital period of the binary system, the possible precession
period of a tilted accretion disk, accretion cycles, etc, (f)
accreting millisecond X-ray pulsars: these systems are thought to be
the evolutionary progenitors of recycled radio millisecond pulsars.
