I will give a broad overview of the scientific targets of the Einstein Telescope in astrophysics, cosmology, and fundamental physics.
Observations of binary black holes mergers from the LIGO-Virgo interferometers provide a window to investigate the highly dynamical regime of gravity as well as the nature of astrophysical black holes. The black hole born from the merger of its progenitors emits gravitational waves with a characteristic spectrum, the so-called ringdown, whose direct detection provide informations about the...
Primordial black holes form in the early universe and can give rise to mergers at high redshift. This distinctive feature can be exploited by 3G detectors to distinguish primordial binaries from the ones generated by other astrophysical formation channels. By considering a primordial black hole population compatible with current gravitational wave data, we show that 3G detectors such as the...
Gravitational wave measurements of the tidal deformability
in neutron-star binary coalescences are golden sources to infer properties of the still unknown equation of state (EoS) of dense matter above
the nuclear saturation density. In this talk I will show how, using a
Bayesian-ranking test we can quantify the ability of current and future gravitational-wave observations to discriminate...
The first direct detection of gravitational waves by the LIGO and VIRGO collaborations has opened up new avenues to explore the Universe. Currently operating and planned gravitational wave detectors mostly focus on the range below 10 kHz, where signatures from known astrophysical sources are expected to be discovered. However, based on what happens with the electromagnetic spectrum, there...
