An expert on the ultra-dense, rapidly spinning and highly
magnetized astronomical objects known as pulsars will give a free presentation
at the University of Wisconsin-Stevens Point. It is open to the public.
Megan DeCesar will present “Pulsars: The Universal Timekeepers” on
Thursday, April 3, at 7:30 p.m. in Trainer Natural Resources Building Room 170.
Pulsars, or pulsating stars, emit beams of electromagnetic radiation that, from
earth, appear to wink on and off at regular intervals.
DeCesar
is a postdoctoral research associate at UW-Milwaukee. She studies pulsars
at radio, X-ray and gamma-ray wavelengths, with the goal of discovering new
pulsars, understanding pulsar emission geometry, constraining the physics of
the very dense matter of which pulsars are made and testing the accuracy of
general relativity. She received her bachelor’s degree from the
Pennsylvania State University and a Ph.D. from the University of
Maryland.
Her
visit is sponsored by the UW System Women and Science program and the Department
of Physics and Astronomy at UW-Stevens Point.
