Since the inaugural meeting of 1998 (held at Caltech's Capra ranch near San Diego) Capra meetings have been bringing together relativists interested in the problem of radiation reaction in relativity and its application to extreme-mass-ratio inspirals (EMRIs) as astrophysical sources of gravitational waves. The meetings address an important open problem in gravitational theory, made particularly relevant by the exciting prospect of directly observing gravitational waves from EMRIs in the near future.

Following the Capra tradition, the meeting will focus primarily on aspects of the self-force in general relativity, although broader topics related to gravitational-wave physics will also be discussed. As usual, the meeting will be informal: there will be no registration fee and no proceedings.

The program will include a few hour-long invited review talks, numerous short contributed presentations (about 20 minutes each), and ample time for open discussions. Contributed talks on all aspects of the radiation reaction problem (including related topics such as EMRI astrophysics or data analysis) are welcome. However, due to time limitations, and in order to leave ample time for discussions, we might not be able to accommodate for every submitted abstract. The talks will take place from June 11 to June 13, with June 14th and the morning of Friday June 15th left for those who might want to stay for further interactions/work. The meeting will close by Friday noon, allowing for those who wish to enjoy Washington DC and the Chesapeake Bay.

For any additional information, questions, or queries regarding this conference, please contact any of the local organizers.
