Extragalactic Astrophysics. Over the last decade, a "standard model of cosmology" has emerged, in which the present expansion of the Universe is dominated by the dark energy and dark matter, and cosmic structures formed from the primordial density fluctuations that had a scale-invariant power spectrum. One of the frontiers of current cosmology is to study the epoch of first structure formation, and how predictions for this epoch can be confronted with future observations. Our group has published several papers in the recent past on this filed.


Contemporary data analysis tools are inadequate for future large data sets, even with the most powerful supercomputers existing or projected. A new approach to these problems consists of a powerful mixture of advanced computer science, statistics, and group theory. We are developing tools and techniques which allow the analysis of such large data sets on human time-scales using reasonable resources.

Gravitational Wave Astrophysics (participation in LIGO). Theoretical prediction of gravitational wave backgrounds motivated by LIGO/Advanced LIGO. The Eotvos Gravity Research Group (EGRG) conducts a vigorous research program aiming to study gravitational waves of cosmic origin and to contribute to the development of advanced interferometric gravitational wave (GW) detectors.

Nucleosynthesis. Our recent research interests have been concentrated on nuclei far from stability (neutron and proton halos), nuclear astrophysics, the structure and reactions of light nuclei, and nuclear parity violation.
