Gravitational Wave Astronomy
The gravitational wave (GW) spectrum of astrophysical sources extends over several decades in frequency, from nHz to kHz. At the kHz end, the Advanced LIGO GW observatories have completed their first data-taking period with sensitivity improved by an order of magnitude over initial detectors. The new data will yield unprecedented probes of neutron star (NS), black hole (BH) and supernova physics in the gravitational wave channel, including novel probes of the populations of ultra-compact BH and NS binaries. At nHz frequencies pulsar timing arrays are already piercing through the expected range of GW signals from massive BH binaries, with latest results starting to constrain their astrophysical population and dynamical evolution. Looking to the future, the mHz regime will be opened by the eLISA mission, which has now been selected by ESA for the L3 launch slot, opening the high redshift GW Universe. Gravitational Wave Astronomy brings a completely new view on the Universe, probing 'dark astrophysics' inaccessible to electromagnetic probes.
