Il rivelatore di onde gravitazionali di terza generazione Einstein Telescope pone sfide tecnologiche di straordinaria complessità, tra cui la realizzazione del più grande sistema da vuoto mai concepito per operare in regime di ultra-alto vuoto.

Il progetto prevede un sistema da vuoto costituito da un tubo di un metro di diametro per una lunghezza complessiva di circa 120 km, operante a...

54. Noise attenuation in gravitational waves interferometers

Detecting gravitational waves generated Megaparsecs away from Earth means measuring distance variations comparable with a proton's radius. Measuring such small distances means interfacing with a plethora of disturbances such seismic, thermal and quantum noises. In this talk some basics of how seismic noise is attenuated in the Virgo experiment will be displayed, accompanying the talk with some...

55. Deep Reinforcement Learning for Lock Acquisition Optimization in Non Linear Optical Cavities.

The PhD project explores the application of Deep Reinforcement Learning (DRL) to optimize the locking procedure of high-finesse Fabry-Pérot (FP), critical components in gravitational wave (GW) detectors such as Advanced Virgo, LIGO and KAGRA. Speeding up the locking procedure and establishing the resonance condition of these cavities are crucial aspects to improve the detector’s duty cycle,...

57. Strong-gravity tidal effects in black-hole systems and their signatures in gravitational waves

Gravitational-wave observations have opened a new window on the strong-gravity regime of General Relativity. While most detected signals are interpreted assuming isolated compact binaries, many astrophysical systems are expected to evolve in complex environments, such as the dense regions surrounding supermassive black holes in galactic nuclei. In these scenarios, external gravitational fields...
