29th Capra Meeting on Radiation Reaction in General Relativity
workshop
The Capra meeting is an annual conference on the topic of radiation reaction in general relativity. The primary focus of these conferences is the development of the gravitational self-force approach to model extreme mass ratio inspirals and further our understanding of the two-body problem in general relativity. This is done in synergy with other well-known modeling techniques such as post-Newtonian theory and numerical relativity. The canonical example of an extreme-mass-ratio inspiral (EMRI) is the inspiral of a stellar-mass compact object into a supermassive black hole. Gravitational waves from these systems are a promising target for the future space-based detector LISA.
The study of radiation reaction and self-force is not limited to EMRIs, and a range of topics and applications to other areas of gravitational physics have been discussed at past Capra meetings; an example is the scattering of massive particles, which is currently an active area of research. The format of the meeting is an amalgamation of a daily invited review talk, short contributed talks and organised discussion sessions.
Following the tradition of past Capra meetings, no registration fee is charged. A contribution of 50 euros to the banquet will be requested at registration for the attendees that would like to join the banquet. Several selected early career researchers will be funded by providing up to 6 nights of accommodation during the conference. Applications will be reviewed by members of the local organising committee and the equity, diversity and inclusion team at Capra.
