L7.00001: Searches for bursts of gravitational waves with LIGO, GEO and Virgo Invited Speaker: The LIGO, GEO and Virgo laser interferometers completed in October 2007 their most recent science runs (fifth science run, S5, for LIGO/GEO and first Virgo science run, VSR1). This presents the most sensitive and longest in duration coordinated observation by the global network of gravitational wave detectors. One of the astrophysical searches that we pursue using data from the laser interferometers targets sources of short-duration, arbitrary-shaped gravitational wave signals. Such signals, referred to as bursts, may accompany events like core-collapse supernovae, the merger phase of coalescing binary compact stars and gamma-ray bursts (GRBs). In this talk we will present the current status of the analysis of S5 and VSR1 data for such bursts of gravitational radiation. We will also discuss the advantages of the coordinated observations offered by the global network of detectors. We will finally highlight our first S5 result attained in a search for gravitational wave bursts in association with GRB070201 and discuss the prospects of ongoing burst searches.

L7.00002: Searches for gravitational waves from the inspiral of binary neutron stars and black holes Invited Speaker: We report on searches for gravitational waves from the coalescence of compact binaries in data from the LIGO detectors. These searches target signals from inspiralling binary systems with total masses less than $35 M_\odot$ and for inspiral waves associated with short hard gamma ray bursts. We will also give an overview of ongoing searches being performed by the LIGO Scientific and Virgo collaborations. [Preview Abstract] |

L7.00003: Extending our reach: the next decade of GW detectors Invited Speaker: The international gravitational wave community has succesfully completed a year of data taking with first generation detectors operating at design sensitivity and looks forward to a decade of upgrades. The upgrades will improve the sensitivity by approximately an order of magnitude with a thousand-fold increase in the detection rate. This talk will review the current and proposed GW detectors planned for operation by 2018. [Preview Abstract] |
