RE: Hunting gravitational waves with Virgo and LIGO

I hope this will provide enough information to the participants. I guess we will only know if they raise their voice :D

I am happy to read that the article was simple enough. With physics, it is easy to become non-comprehensive in no time ^^

I hope you will join us for our next meetup!

I agree that this was very comprehensible for high level physics. I’m still not 100 percent clear on how the interference is detected, but I think that’s beyond the scope of this post.

I may try to answer... ;)

To make it simple without entering into all glory details.

• the pattern of all potential background noise is catalogued;
• the pattern of the signal is catalogued.

When something that does not correspond to any known background is seen, one checks whether it is also detected in the other detectors. If yes, we have a wave.
