I'm curious as to why ligo is the only project ever mentioned, particularly given that they have to work with virgo and geo600 to be able to triangulate their observations - a two axis interferometer only gives you partial information.
Better PR team?
- camillomiller 11y agoIn Italy there's a lot of buzz around Virgo (located near Pisa), but I had the impression that it's mostly national talk, too.
- madaxe_again 11y agoYeah - I visited virgo years ago when they were about to start calibration - it's super cool, but then again, I think michelson-morely interferometers are cool as a category. They were invented for a not dissimilar purpose - testing the properties of the luminiferous aether seeing if light and matter moved at different rates depending on the earth's motion through the aether. The result was negative, and a patent clerk got thinking. Now his ideas are being put to the test with the same apparatus. So cool.
- ISL 11y agoIf you look carefully at the press release, the group that's presenting on Thursday is the LSC, the LIGO Scientific Collaboration, which includes VIRGO and GEO. It's one big group, as everyone in the field shares hardware techniques and analysis techniques.
- madaxe_again 11y agoYes, I know that, but the press only mention ligo. I'd assume because it's the only American one.
- gaur 11y agoThe new Virgo detector is not operational yet. GEO600 is operational, but it is much less sensitive that the Ligo detectors.
