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) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

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 …

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 …

We report on gravitational-wave discoveries from compact binary coalescences detected by
Advanced LIGO and Advanced Virgo in the first half of the third observing run (O3a) between …

The concept of stars being tidally ripped apart and consumed by a massive black hole
(MBH) lurking in the center of a galaxy first captivated theorists in the late 1970s. The …

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

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

ABSTRACT The European Space Agency's Planck satellite, which was dedicated to
studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It …

We report the observation of gravitational waves from a binary-black-hole coalescence
during the first two weeks of LIGO's and Virgo's third observing run. The signal was recorded …
