Animation: effect of gravitational waves on test masses (2D)
Beam-splitter mirror and its payload suspended inside the tower (2014)
The Advanced Virgo beam-splitter mirror an its payload have been inserted inside the vacuum tank and suspended to its suspension in December 2014.
In this picture, the mirror was still protected with a thin layer of polymer (seen in pink) to protect its surface.

ADC board with 16 channels
This custom electronic board is able to digitize 16 voltage signals measured by the Virgo detector at sampling frequencies of few tens of kilohertz in general. The ~35 boards used in Advanced Virgo are all synchronized on the GPS time within 50 ns.

NASA’s Chandra X-ray Observatory and ground-based optical telescopes have located the supernova SN 2006gy in 2006
NASA’s Chandra X-ray Observatory and ground-based optical telescopes have located the supernova SN 2006gy in 2006.
The top panel of the image is an artist’s impression of a supernova.
The bottom left panel is an optical observation and the bottom right panel is an X-ray observation. In these two panels, the supernova is the bright spot on top-right of the image. The nucleus of the galaxy where the supernova happened is the bottom spot.

Pulsar PSR B1509-58 observed by Chandra in X-rays.
Advanced Virgo will search for gravitational waves coming from known pulsars (neutron stars from which we receive periodic light flashes).
A pulsar is observed at the center of the image: it is a small, dense object only 20 km in diameter. It is responsible for this beautiful X-ray nebula that spans 150 light years.

Sketch of a Virgo mirror suspension used to reduce the seismic noise
The Virgo suspension is about 8 meter high and is placed in a vacuum tank. It is composed of a series of pendulum that reduce the horizontal seismic vibrations that reach the mirrors. Horizontal vibration dampers are also visible. The last suspended element is a mirror payload.
