The 39th Pacific Coast Gravity Meeting will be held at Caltech, Pasadena, CA, on March 31 and April 1, 2023. In the tradition of the Pacific Coast Gravity Meetings, students and postdocs are strongly encouraged to participate, and all areas of gravitational physics—classical and quantum, theory and experiment—are welcome. We would like this meeting to serve as a communication medium among all branches of gravitational physics. Because this is a regional meeting, many participants will be from the Western United States, but all are welcome.

The meeting is free to attend (no registration fee). Unfortunately, we are not able to provide financial assistance to speakers and participants. A prize (sponsored by the APS Division of Gravitational Physics) will be awarded for the best student talk.

It is a pleasure to dedicate this conference to Jim Isenberg, who started these meetings and has kept them going for 39 years.

Important dates

  • Feb. 25: Saga Motor Hotel room booking cut-off (see Lodging page)
  • Mar. 1: Registration Deadline
  • Mar. 21: Schedule Announcement
  • Mar. 31 - Apr. 1: See you all at PCGM!

Student prize

A monetary prize will be awarded to the best talk given by a graduate student, as determined by a panel of faculty judges. If you are a PhD student, be sure to answer "Yes" to the "Are you a student?" question when registering in order to be considered. This prize is sponsored by DGRAV, the Division of Gravitational Physics of the American Physical Society; criteria for the award can be found here.
