Seminars and Colloquia at ESO Garching and on the campus
The km-scale interferometric detectors of gravitational waves LIGO and Virgo have demonstrated the target sensitivity and have realized a world wide network of detectors. The data collected so far have allowed to put upper limits on several sources, but no detection has been done so far.
The projects to upgrade LIGO and Virgo to second generation interferometers, capable of increasing the detection rate by a factor ~1000 have been funded recently. The construction of Advanced LIGO and Advanced Virgo has started. The upgraded detectors are expected to start again taking science data in 2015.
In the talk we review the results achieved so far and the perspectives of the advanced detectors.
