For centuries, humankind has observed the sky with the naked eye. In modern times we have learnt to study our universe by capturing the light – in a very wide range of wavelengths – as well as charged particles, known as cosmic rays, and neutrinos, which could be emitted by very different astrophysical objects. All […]

The Virgo collaboration and the LIGO Scientific Collaboration report the three-detector observation of gravitational waves. This result highlights the scientific potential of a global network of gravitational wave detectors, by delivering a better localization of the source and access to polarizations of gravitational waves.
Absolutely yes, you are very welcome!
This post is part of a series about quick questions and answers about the Virgo experiment and the science of gravitational waves. Do you have a quick question? Tell us and we will reply! What is the Virgo Collaboration? The Virgo Collaboration is an international team of researchers, engineers, and technicians working together on the […]
The information collected by the network of LIGO and Virgo instruments will provide a rather rough direction of the sources of gravitational waves in the sky, but follow-up observations will help to identify the location of gravitational wave sources
Virgo can be seen as a special kind of telescope, since it looks for phenomena happening far in the cosmos.
Today there is an initial network of gravitational wave interferometers around the world.
Advanced Virgo will be sensitive to length changes in the 3-km arms which are on the order of a billionth of a billionth of a meter…
No source on Earth is capable of producing gravitational waves large enough to be detected by Virgo, but many violent phenomena in the Universe could generate detectable signals.
