One century after its formulation, Einstein's general relativity (GR) has made remarkable
predictions and turned out to be compatible with all experimental tests. Most of these tests …

In this article, I introduce ideas and techniques to extract information about the equation of
state of matter at very high densities from gravitational waves emitted before, during and …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

Neutron stars and quark stars are ideal laboratories to study fundamental physics at supra
nuclear densities and strong gravitational fields. Astrophysical observables, however …

General Relativity has shown an outstanding observational success in the scales where it
has been directly tested. However, modifications have been intensively explored in the …

The nuclear symmetry energy characterizes the variation of the binding energy as the
neutron to proton ratio of a nuclear system is varied. This is one of the most important …

Determining the Equation of State (EOS) of dense neutron-rich nuclear matter is a shared
goal of both nuclear physics and astrophysics. Except possible phase transitions, the density …

A number of recent works have highlighted that it is possible to express the properties of
general-relativistic stellar equilibrium configurations in terms of functions that do not depend …

Among the various oscillation modes of neutron stars, f-and g-modes are the most likely to
be ultimately observed in binary neutron star mergers due to their relatively large coupling …

The effect of dark matter (DM) on f-mode oscillations in DM admixed neutron stars (NSs) is
investigated in a comprehensive analysis with particular attention to the role of the nuclear …
