Joel Weisberg, Herman and Gertrude Mosier Stark Professor of Physics and Astronomy and the Natural Sciences, has completed the final National Science Foundation grant project in his long career at Carleton College.

The eighth in a line of NSF grants extending back to 1987, this grant – "RUI: Relativistic Gravitation, Pulsar Beams and Birth Processes, and the Interstellar Medium" – permitted Prof. Weisberg and ten Carleton students (Carolyn Raithel, Riqui Geng, Hayden Tornabene, Yuping Huang, Alice Curtin, Matthew Maclay, Alexander McMurtry, Sanjay Chepuri,  Alejandro Gallardo, and Carl Thomas) to advance his research into relativistic gravitation, the interstellar medium, and pulsar beaming and evolution, which included further study of the first binary pulsar, PSR B1913+16. Weisberg and six of the Carleton students conducted some of the research at international sites: the Arecibo Observatory in Puerto Rico and the Centre for Astrophysics and Space Sciences and the Parkes Observatory in Australia.

To date, Weisberg and his collaborators have presented two posters on this work at meetings of the American Astronomical Society and published six articles in the Astrophysical Journal and the Monthly Notices of the Royal Astronomical Society. Further presentations and publications are forthcoming, Weisberg having now begun retirement and handed off the binary pulsar project to Dr. Joseph Swiggum, University of Wisconsin, Milwaukee.
