Formation and dynamics of disk galaxies and supermassive black holes
I am working for my PhD with Prof. Lucio Mayer.
at the University of Zurich – Irchel (you
can find my Uni webpage here). Since
he is also Visiting Professor at ETH, the Extragalactic Astrophysics
and Observational Cosmology Group kindly hosts me at the Hoenggerberg
campus.
My work is mainly focused on applying N-body simulations (carried out
with the GASOLINE code on the zBox clusters at the ITP and the
Cray XT5 cluster Rosa at CSCS) to two topics:
mergers
between disk galaxies – we are studying the role
played by gas dynamics in driving the pairing and growth of the
central supermassive black holes during minor mergers, and how
the different structure predicted for galaxies at high redshift
could change these results when the merger rate was higher
(z~3);
formation
of disk galaxies – simulations of the birth of
realistic disk galaxies in a cosmological context are facing
many problems, mainly due to the high numerical resolutiion required
and to the poor understanding and modeling of gas
dynamics and star formation; we are performing a set of N-body /
SPH simulations in order to gain a quantitative understanding of
the role of the resolution effects on the formation of the first protogalactic disks.
