After decades of null results, the gravitational wave events GW150914 and GW170817 have ushered us in the era of gravitational wave astronomy. Observations of gravitational waves from the inspiral and merger of black-hole and neutron-star binaries, also in conjunction with EM-observations, are probing important aspects of astrophysics, cosmology and fundamental physics -- and this is just the...
The second generation of Gravitational wave interferometers is a network of advanced detectors distributed in three different continents. They will restart the operation in 2023, including the fourth detector in Japan, bringing new data to the gravitational wave astronomers.
In this talk, after a brief introduction, we will discuss results of astrophysical interest already obtained and...
3rd generation (3G) gravitational wave (GW) observatories will pick up in the next decade, the legacy of the current generation of GW detectors, Advanced LIGO and Advanced Virgo, allowing the exploration of almost the entire Universe through GW signals. Einstein Telescope (ET) is the pioneer project aiming to the realisation of a 3rd generation Gravitational Wave Observatory in Europe....
A defining characteristic of gamma-ray bursts (GRBs) is the presence of jetted outflows. These jets are shaped by their launching mechanism and interactions with the environment (both close and further distant) of the GRB, as revealed to us when the jets decelerate from the ultra-relativistic to the non-relativistic. Due to its close proximity and off-axis orientation, multi-messenger event...
The recent discovery of gravitational waves and high-energy cosmic neutrinos, marked the beginning of a new era of the multimessenger astronomy. These new messengers, along with electromagnetic radiation and cosmic rays, give new insights into the most extreme energetic cosmic events. The detection of gravitational waves from core-collapse supernova explosions is a challenging task, yet to be...
Standard sirens have been the central paradigm in gravitational-wave (GW) cosmology so far. From the GW signature detected from the compact binary mergers, it is possible to directly measure the luminosity distance of the source, and if additional information on the source redshift is provided, a measurement of the cosmological expansion can be performed. In this talk, I will present the most...
In $\sim 2035$ LISA will be able to detect the gravitational waves (GWs) from the coalescence of massive black hole binaries (MBHBs) in the mass range $[10^5, 10^7] \, \rm M_{\odot}$ up to $z\sim 10$. If the merger happens in a wet environment, copious amounts of radiation across the entire electromagnetic (EM) spectrum is expected to be produced by the accretion of the gas onto the...
More than 50 years ago, Apollo and Luna missions placed five Laser Retroreflector Arrays (LRAs) of Cube Corner Retroreflectors (CCRs) on the surface of the Moon. Through a technique known as Lunar Laser Ranging (LLR), it has been possible to perform high accuracy/precision measurements of the Earth-Moon distance by firing short laser pulses from ground Laser Ranging Stations to these LRAs on...
