Abstract

Virgo is a gravitational wave detector based on a 3 km long laser interferometer. After a first period of data taking between 2007 and 2011, a major upgrade called Advanced Virgo was prepared starting from 2009. After its implementation and commissioning Advanced Virgo started operation in 2017, joining the Advanced LIGO O2 run. In this period Advanced Virgo contributed to the first detection of gravitational waves from the binary neutron stars merger called GW170814. After a period of improvements and commissioning, in April 2019 Advanced Virgo started a new period of observation in coincidence with Advanced LIGO, during the so-called run O3. In the meantime, a new upgrade called Advanced Virgo Plus is being prepared. The first phase of this upgrade will be implemented at the end of O3 and completed by 2022, when the run O4 is planned to start. A second phase of upgrade is planned to be implemented between 2023 and 2024 and to be completed before the start of O5 in 2025.
