Session H1 - Issues in Gravitational Radiation.
INVITED session, Sunday morning, April 29
Grand Ballroom North/Central, Renaissance Hotel$
Solar-mass compact objects in orbital motion around massive black holes emit low-frequency gravitational waves that can be measured by a space-based interferometric detector such as LISA (Laser Interferometer Space Antenna). The detailed modeling of these sources, to the extent that templates could be provided for data analysis, requires a detailed computation of the motion over a very large number of orbital cycles. This, in turn, requires a detailed understanding of radiation-reaction effects in strong gravitational fields. I will review some of the recent work on this topic, starting with the foundational aspects and concluding with concrete applications.
