SUMMARY:Joint LLC Seminar with Karsten Danzmann
DESCRIPTION:Contact: francesca.curbis@maxiv.lu.se\n\nKarsten Danzmann&nbsp\
 ;from Max-Planck-Institut für Gravitationsphysik&nbsp\;and Institut für 
 Gravitationsphysik der Leibniz Universität Hannover will tell us about&nb
 sp\;Gravitational Wave Astronomy: We can hear the dark universe with laser
  interferometers!“Fika” (coffee and cake) will be served before the me
 eting\, from 15:00.Abstract:We have been looking at the universe with our 
 eyes for thousands of years. Butover 99% of the universe is dark and will 
 never be observed with electromagneticwaves. Since September 14\, 2015\, e
 verything has changed: gravitational waves havebeen discovered! We have be
 en given a new sense and can finally hear the dark side ofthe universe.Sev
 eral km-size laser interferometers are now operating on the earth\, usings
 ensitivities at the quantum limit and also beyond the standard quantum lim
 it. Ourlasers from Hannover are now the workhorse of most laser observator
 ies in theworld.The first sounds we heard came from completely unexpectedl
 y heavy black holes.Gravitational waves have now become a new kind of astr
 onomy. Hundreds of suchevents are now recorded almost daily\, with frequen
 cies ranging from a few hertz to afew kHz. And in 2035 we will also be abl
 e to observe the low-frequency sources withLISA\, a laser interferometric 
 observatory with millions of km of arm length in themHz range. Nobody know
 s what other dark secrets are still waiting for us out there.\n\nMore info
