Talk

Among astrophysical gravitational waves sources yet undetected, of great interest are the binary close encounters involving black holes and/or neutron stars. These systems are characterized by high orbital eccentricities and form via dynamical interactions in dense stellar environments, like globular clusters or Active Galactic Nuclei disks. Their detection could shed light on the different...

31. Astroparticles in the Near-Earth Space and their Effect on Atmosphere and Climate

Talk

Astroparticles can get trapped in the Earth’s magnetosphere. There are a number of measurements of protons, electrons, heavy ions, solar energetic protons, galactic cosmic rays, as well as positrons in near-Earth space. The high-energy electrons in the Earth’s radiation belts were discovered by the first US satellite Explorer-1, which was designed to study cosmic rays. In the proposed project,...

44. The KM3NeT detector and infrastructure: an unprecedented tool for the exploration of deep sea

Giorgio Maria Riccobene (INFN-LNS)

04/03/2024, 17:00

Talk

KM3NeT is an underwater Cherenkov neutrino telescope operating in the abysses of the Mediterranean Sea. It consists of two detectors: one located at 2500m water depth, 40 km offshore South of Toulon (France), in the Ligurian Sea; the other one located at 3500m depth, 90 km offshore South East of Capo Passero (Sicily) in the Ionian Sea.
Each detector is an array of hundreds of mooring lines...

43. Geoneutrinos as probe for deep Earth

Sandra Zavatarelli (INFN - Genova)

04/03/2024, 17:20

Talk

There are still several unanswered fundamental questions concerning our planet and in particular, about the deep Earth, from where we lack direct samples. Geo-neutrinos, electron anti-neutrinos produced in β decays of naturally occurring radioactive isotopes in the Earth, are a unique direct probe of our planet’s interior. If detected, they allow to quantify the amount and distribution of...

50. Influences of environmental noises in the Virgo detector

Irene Fiori (European Gravitational Observatory)

04/03/2024, 17:40

Talk

In order to detect gravitational waves, Virgo measures extremely small variations in differential elongations of the arms. Sources of geophysical and anthropogenic environmental noises, such as wind and railway traffic, can impact on the detector causing transient sensitivity worsening and gaps in data taking. We review the major sources studied during the last observing run and the more...
