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 …

The first generation of stars, often called Population III (or Pop III), form from metal-free
primordial gas at redshifts z∼ 30 and below. They dominate the cosmic star-formation …

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

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 100 years since the publication of Albert Einstein's theory of general relativity saw
significant development of the understanding of the theory, the identification of potential …

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 Gamma-ray bursts (GRBs), can be employed as standardized candles,
extending the distance ladder beyond Type Ia supernovae (SNe Ia, z= 2.26). We …

Monitoring of vibrational eigenmodes of an elastic body excited by gravitational waves was
one of the first concepts proposed for the detection of gravitational waves. At laboratory …

The Einstein Telescope (ET) is going to bring a revolution for the future of multimessenger
astrophysics. In order to detect the counterparts of binary neutron star (BNS) mergers at high …

Cosmological models and their corresponding parameters are widely debated because of
the current discrepancy between the results of the Hubble constant, H 0, obtained by SNe Ia …
