Research
Thessaloniki
has a tradition in Relativistic Astrophysics and it is the largest
relativity group in
Greece, with expertise in many areas of classical general relativity
and cosmology, but focussed
primarily in the study of sources of GWs and detection
techniques.
The group has expertise
in perturbation and post-Newtonian techniques as well as numerical
relativity and has active
collaborations with most of the European relativity groups as well
as groups in the US and Japan.
There are ongoing common projects with Southampton, AEI, Valencia, FSU,
Rome, MPA-Garching
and other groups.
The research interests of the group include:
- Pulsating Relativistic Stars: analysis of spectral
properties,
stability and efficiency for
gravitational wave
emission,
- Numerical Relativistic Astrophysics: equilibrium
properties and
fully relativistic, nonlinear
evolutions in 2D and 3D of rotating relativistic stars
and coalescing binaries,
- Coalescing Binary Systems: study of the individual
characteristics
of each member due to tidal
effects, emission of gravitational radiation and
extraction of corresponding waveforms,
- Gravitational Wave Data Analysis: study of effects of
higher order
post Newtonian terms,
Monte-Carlo simulations to study the errors in the estimation
of the system parameters by networks
of detectors (inverse problem).
- N-Body Simulations of Globular Clusters: study of the
formation of intermediate-mass black holes
and of gravitational-wave capture sources for LISA.
