T2.00001: Exploring the transient universe with gravitational waves Invited Speaker: The first generation of km-scale interferometric gravitational-wave detectors has completed several years of observation at or near their design sensitivity. Their data is being analyzed for a variety of astrophysical sources of gravitational radiation. Although gravitational waves have not yet been detected, a number of upper limits have been set. I will discuss astrophysical implications of searches for transient gravitational-wave sources such as coalescing binary systems of black holes and/or neutron stars, and core-collapse supernovae.

T2.00002: Searches for a stochastic background of gravitational waves Invited Speaker: A Holy Grail of gravitational-wave astronomy is the detection of a cosmological stochastic gravitational-wave background (SGWB) formed in the very early universe. Detection of the SGWB may allow us to probe time scales and energies not accessible with conventional astronomy or accelerators, though there are considerable experimental challenges to overcome. Additionally, the SGWB may be obscured by a stochastic gravitational-wave foreground, interesting in its own right, and produced from the superposition of astrophysical phenomena such as neutron stars. I review mechanisms for the creation of stochastic backgrounds and foregrounds. I discuss data-analysis strategies and the prospects for detection. [Preview Abstract] |
