Center for Gravitation and Cosmology hosts Alt Grav Workshop

Posted by Sara Gil-Casanova on June 01, 2010


Over 40 scientists attended the Alt Grav Workshop, “Gravitational Wave Tests of Alternative Theories of Gravity in the Advanced Detector Era", hosted by UWM’s Center for Gravitation and Cosmology on May 26 and 27.

The goal of the workshop was to plan and scope out work to prepare for the era of advanced gravitational wave detectors, Advanced LIGO and Virgo, expected to come on-line around 2014. Gravitational wave tests of alternative theories of gravity could shed light on some of the most profound challenges facing physics today: from explanations of cosmic acceleration and dark matter to the reconciliation of gravity and quantum theory.

The workshop was structured relatively informally, starting with two lectures by Cliff Will on the gravitational wave physics in alternative theories of gravity. These lectures were followed by focus sessions on gravitational wave bursts, compact binary systems, stochastic background, and continuous waves. Workshop participants enjoyed a number of thought-provoking conferences/altgrav/talks followed by long discussion periods during which gravitational wave sources, data analysis techniques, pipelines, and milestones were proposed and discussed
