30. Dynamical evolution of the Milky Way globular clusters in cosmological timescale: interaction with the central Super Massive Black Hole

The main idea of the work is to perform the dynamic evolution of the orbits of Globular Cluster subsystems (GCs) with a look-back time up to 10 Gyr. This will allow us to estimate the possible interaction of GCs with the Galactic Center (GalC) region, including the influence of the super-massive black hole (SMBH), which has dynamically changed in the past. To reproduce the structure of the...

33. Dark matter in clusters of galaxies

Dark matter (DM) has been originally discovered in clusters of galaxies by Zwicky (1933). These systems currently remain excellent laboratories for probing DM properties through gravitational lensing, and the dynamical equilibrium of cluster visible components (intra-cluster plasma and galaxies). Comparison of the shape of cluster mass density profiles with predictions from cosmological...

31. Gravitational waves observations by LIGO-Virgo and prospects for the future

Fiodor Sorrentino (INFN e Universita Genova (IT))

About 100 gravitational wave signals have been detected by the LIGO-Virgo network during the first three observing runs since 2015. The fourth observing run O4 has recently started with the addition of the KAGRA detector. Several upgrades have improved the detectors' sensitivity, and the rate of GW detections, over the years. In the talk I will describe the past GW observations, the status of...

The measurements of the Earth rotation rate variations, certainly important for Earth science, are relevant also for fundamental physics investigation, as they contain general relativity terms, such as de Sitter and Lense Thirring, and they provide unique data to investigate Lorentz violations. Long term continuous operation and very high sensitivity are required, the limit to be reached to...

29. Evidences of Primordial Black Holes as Dark Matter components

Juan Garcia-Bellido Capdevila (Universidad Autonoma de Madrid (ES))

I will give a review on the Theory of Primordial Black Holes and their prospects of detection from a wealth of cosmological, astrophysical and GW observations.
