The understanding of stellar structure represents the crossroads of our theories of the
nuclear force and the gravitational interaction under the most extreme conditions observably …

The ever-increasing number of detections of gravitational waves (GWs) from compact
binaries by the Advanced LIGO and Advanced Virgo detectors allows us to perform ever …

Abstract The Einstein Telescope (ET), a proposed European ground-based gravitational-
wave detector of third-generation, is an evolution of second-generation detectors such as …

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 …

The recent discovery by Advanced LIGO and Advanced Virgo of a gravitational wave signal
from a binary neutron star inspiral has enabled tests of general relativity (GR) with this new …

In the present Letter, we consider a class of extended scalar-tensor-Gauss-Bonnet (ESTGB)
theories for which the scalar degree of freedom is excited only in the extreme curvature …

We identify a class of scalar-tensor theories with coupling between the scalar and the Gauss-
Bonnet invariant that exhibit spontaneous scalarization for both black holes and compact …

In a single process, the merger of binary neutron star systems combines extreme gravity, the
copious emission of gravitational waves, complex microphysics and electromagnetic …

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 …
