Physicist to First Observe Gravitational Waves Speaking at BNL, October 11


Nergis Mavalvala, Marble Professor of Astrophysics at MIT, will discuss “The Warped Universe: the one hundred year quest to discover Einstein’s gravitational waves” on Wednesday, October 11, at 4 pm at Brookhaven National Laboratory, Berkner Hall.

Dr. Mavalvala, 2010 recipient of a MacArthur “genius” award, is a physicist whose research focuses on the detection of gravitational waves and quantum measurement science. She is a longtime member of the scientific team that announced in 2016 the first direct detection of gravitational waves from colliding black holes by the Laser Interferometer Gravitational-wave Observatory (LIGO). The gravitational waves that LIGO detected are ripples in the spacetime fabric caused by the motion of compact, massive astrophysical objects such as black holes and neutron stars. Since the nature of gravitation is inherently different from electromagnetism, gravitational wave astrophysics provides a radically different window into the universe.

In the quest for ever greater sensitivity in the LIGO detectors, Mavalvala has also conducted pioneering experiments on generation and application of squeezed states of light, and on laser cooling and trapping of macroscopic objects to enable observation of quantum phenomena in human-scale systems.
