The Astrophysical Multimessenger Observatory Network (AMON) aims to connect the world’s leading high-energy and multimessenger observatories. AMON’s objective are to evoke the discovery of new multimessenger phenomena, exploit these phenomena as tools for fundamental physics and astrophysics, and explore archival datasets in search of multimessenger activity. Present projects include...

The Pierre Auger Observatory is not only the world's largest cosmic-ray observatory, but also an efficient detector of cosmic particles other than nuclei. Using its enormous exposure, the Observatory is a competitive player in searches for ultra-high energy neutrinos, photons, and even particles that could emerge from theories beyond the standard model of particle physics. We present our...

Last year the Tibet ASgamma experiment reported the observation of a diffuse gamma-ray emission from the Galactic plane with energy up to the PeV. This finding seems to be confirmed by LHAASO preliminary results. Both measurements provide the first evidence of a diffuse gamma-ray emission throughout the Galaxy up to such high energies.

Starburst galaxies (SBGs) and more in general starforming galaxies represent a class of galaxies with a high star formation rate (up to 100 Mo/year). Despite their low luminosity, they can be considered as guaranteed “factories” of high energy neutrinos, being “reservoirs” of accelerated cosmic rays and hosting a high density target gas in the central region. The estimation of their point-like...

Bursts (GRBs) detected by the Fermi and Swift satellites during the second
part of the third observing run (O3b) of Advanced LIGO and Advanced Virgo,
from 2019 November 1 to 2020 March 27. This search is carried out with two
different methods, a modeled search targeting compact binary mergers with
at least one neutron... -

In this talk, I will present the latest results by the LIGO-Virgo-Kagra
Go to contribution page
Collaboration for the targeted search for continuous gravitational waves
(GWs) from 236 pulsars. I will also present the first results using the
5n-vector method on the same set of pulsars. Using data from the third
observing run of LIGO and Virgo (O3) combined with data from the second
observing run (O2), no evidence... -

The gravitational wave detector Advanced Virgo+ is currently in the commissioning phase in view of the fourth Observing Run (O4).
The major upgrades with respect to the Advanced Virgo configuration is the implementation of an additional recycling cavity, the Signal Recycling cavity at the output of the interferometer (SRC), to broad the sensitivity band and the Frequency Dependent Squeezing...

One of the fundamental noise in gravitational waves detectors is the so called Quantum Noise, that is related to the intrinsic quantum nature of the laser used to interrogate the GW interferometers, i.e. to the uncertainty on amplitude and phase of the coherent state of light that couples with the vacuum fluctuations. Due to the frequency dependent opto-mechanical response of the GW ...

While completing the commissioning phase to prepare the Virgo interferometer for the next joint Observation Run (O4), the Virgo collaboration is also finalizing the design of the next upgrades to the detector to be employed in the following Observation Run (O5). The major upgrade will concern decreasing the thermal noise limit, which will imply using very large test masses and increased laser...

The Einstein Telescope (ET) is a planned European 3rd Generation Gravitational Wave (GW) Observatory, a new research infrastructure designed to observe the entire Universe using gravitational waves. ET will be a multi-interferometer observatory aiming to increase a factor of ten the present detector sensitivity and to explore a universe volume one thousand bigger. We will give an overview of...
