Research Interests:

Up to now I have been working mostly on numerical simulation of compact objects, like black holes, neutron stars, and accretion disks. Among the studied scenarios, I am particularly interested in binary neutron-star systems. There are several reasons why the study of such systems is of paramount importance for contemporary astrophysics (and physics). In the first place, binary neutron-star systems are the best candidate source for explaining a class of gamma-ray bursts, the most energetic explosions in the Universe. Gamma-ray bursts are observed daily by satellites and telescopes, but their origin is still largely mysterious. Then, binary neutron-star systems are powerful sources of gravitational radiation and there are huge experimental efforts to measure them, especially with laser interferometric detectors. In order to make the detection possible, the accurate knowledge of the gravitational waveform may be of crucial importance. Furthermore, once gravitational waves from binary systems are measured, a wealth of information on compact objects will become available, and most notably information about the equation of state of very high-density matter.
In the future, I intend to expand my research field to include Laboratory Astrophysics, together with the colleagues in the department.

Luca Baiotti received his Ph.D. in astrophysics at SISSA (International School of Advanced Studies), in Trieste (Italy) in 2004. He then worked as a postdoc at the Max-Plank-Institut für Gravitationsphysik, Albert-Einstein-Institut, in Potsdam (Germany) in the period 2004-2007 and as a JSPS fellow at the University of Tokyo (2007-2008) and at Kyoto University (2009).
He is presently Professor at the Institute of Laser Energetics at Osaka University.
