Although based upon a well established theory, gravitational wave detection was seen as an exotic research. Nowadays, observational astrophysics is strongly dependent on the technology advancements meant to further improve the sensitivity of present detectors.
The path that drove to the present scenario and the overall perspective
about the main features of the various detectors, including...
In January 2025, the European Space Agency (ESA) adopted the Laser Interferometry Space Antenna (LISA) to be implemented as the second "Large Mission" of the Cosmic Vision program, with a target launch date of 2035. LISA aims to create an orbiting observatory for gravitational waves, opening the astrophysically rich band from 0.1 mHz to 1 Hz. It will use laser interferometry to measure the...
The detection of Gravitational Waves (GWs) opened a new window on the Universe. The combined observation of GW and electromagnetic signals from astrophysical phenomena in 2017 signed the beginning of the Multi-messenger Astronomy.
While LIGO-Virgo-KAGRA Collaborations keep on detect GWs, a new generation of GW observatories is under preparation and will take over in the next decade, allowing...
The rotational stability of a subset of the “recycled” pulsars not only paves the way to high precision tests of the gravity theories, but allows us to use them as components of a galactic scale gravitational wave detector, dubbed Pulsar Timing Array (PTA). That provides the possibility to search for gravitational waves (GWs) in the ultra-long period range, between a few months to few decades,...
For over three decades, extragalactic high-energy transients were divided into two main classes: long duration gamma-ray bursts (GRBs) from the core-collapse of massive stars, and short duration GRBs from the coalescence of two compact objects. This common notion was confirmed by the ground-breaking discovery of the gravitational wave transient GW170817, which provided direct and unambiguous...
Starting with the first detection of gravitational waves (GWs) in September 2015, a total of 90 compact binary coalescences have been identified during the first three observing runs of the LIGO-Virgo-KAGRA (LVK) collaboration, including mergers between black holes (BHs), neutron stars (NSs) and mixed NS-BHs. These GW observations allowed us to infer some properties of the NS and BH...
Gravitational wave science exerts on the general public the fascination of Astronomy and, at the same time, stimulates the curiosity of fundamental physics. Probably also for this reason, it enjoys considerable popularity: discoveries and results, concerning this field of research, are often in the limelight of global communication.
This popularity offers a range of unprecedented...
Super-Kamiokande is a 50-kton Cherenkov water detector currently
operating in Japan, primarily aimed at the study and detection of
neutrinos. Many efforts are being made to detect neutrinos from
astrophysical origin, especially in the context of multi-messenger
astronomy. In this contribution, the development of an online follow-up
system for gravitational waves detected during the...
