Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

The Λ CDM model provides a good fit to most astronomical observations but harbors large
areas of phenomenology and ignorance. With the improvements in the precision and …

Abstract The Einstein Telescope (ET), the European project for a third-generation
gravitational-wave detector, has a reference configuration based on a triangular shape …

Gamma-ray bursts (GRBs) are divided into two populations,; long GRBs that derive from the
core collapse of massive stars (for example, ref.) and short GRBs that form in the merger of …

The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

Abstract The Laser Interferometer Space Antenna (LISA) has two scientific objectives of
cosmological focus: to probe the expansion rate of the universe, and to understand …

Abstract The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders
about the fundamental theory of nature at play in the extreme gravity regime, where the …

▪ The Hubble parameter, H 0, is not an univocally defined quantity: It relates redshifts to
distances in the near Universe, but it is also a key parameter of the ΛCDM standard …

The second Gravitational-Wave Transient Catalog, GWTC-2, reported on 39 compact binary
coalescences observed by the Advanced LIGO and Advanced Virgo detectors between 1 …

This Horizon Study describes a next-generation ground-based gravitational-wave
observatory: Cosmic Explorer. With ten times the sensitivity of Advanced LIGO, Cosmic …
