SEMINARIO DI FISICA TEORICA:Extracting the physics from gravitational waves observationsWalter Del Pozzo (UNIPI and INFN)14:30Aula NewtonAbstract. The observation of gravitational waves (GW) from coalescing compact binaries provides extraordinary insights into the dynamics of space-time. Such observations allowed to directly measure the physical parameters of the merging systems, to perform unprecedented tests of general relativity (GR), put constraints on the equation of state of neutron stars and even measurements of the Hubble constant. The aforementioned measurements are, however, non-trivial and require the development of robust and reliable statistical methods capable of extracting information from the GW signal embedded in the instrumental noise floor. In this talk, I will review the statistical foundations of the methods developed over the years to extract physical information from GW observations. I will introduce the Bayesian theory of probability and describe its applications to the problem of GW data analysis and to more advanced applications as tests of GR, nuclear physics and cosmological measurements.LINK: http://www.pr.infn.it/--Sebastiano Bernuzzihttp://www.fis.unipr.it/~sebastiano.bernuzzi/
