Searches for gravitational waves from astrophysical sources
Gabriela Gonzalez, for the LIGO Scientific Collaboration

Interferometric gravitational wave detectors have achieved unprecedented sensitivity to gravitational waves, expected from astrophysical sources of different kinds: brief transients from violent events like supernova explosions and collisions of neutron stars and black holes, coalescence of binary compact systems, continuous waves from rotating systems, and and a possible stochastic background of gravitational waves. I will describe the astrophysical sources generating gravitational waves in the frequency band of Earth based detectors, and the methods used to search for their signals. I will present some of the results obtained in data collected with the LIGO and GEO detectors, as well as describe the prospects for the present and future detectors.
