“This is a very exciting time in astronomy that took a lot of people and many years to get to,” said Gonzalez, a professor of physics and astronomy at Louisiana State University.

LIGO spokesperson examines the detection of gravitational waves

LOS ALAMOS, N.M., Sept. 15, 2016—Gabriela Gonzalez, spokesperson for the Laser Interferometer Gravitational-Wave Observatory (LIGO) Scientific Collaboration, will discuss the observation of gravitational waves at 7:30 p.m. Sept. 19 in the Grand Ballroom at the Eldorado Hotel in Santa Fe; the free lecture is open to the public.

“This is a very exciting time in astronomy that took a lot of people and many years to get to,” said Gonzalez, a professor of physics and astronomy at Louisiana State University. “However, this is only the beginning and there’s a lot more to come.”

For the first time, scientists in 2015 used LIGO to observe gravitational waves, ripples in the fabric of space-time that arrived at Earth from a cataclysmic event in the distant universe. Analysis of the signals by the LIGO Scientific Collaboration and the Virgo Collaboration revealed that LIGO detected the gravitational waves that resulted from the merging of two black holes. This scientific milestone marked the beginning of gravitational wave astronomy.

The observation of gravitational waves also confirmed a significant prediction of Albert Einstein’s general theory of relativity and opened an unprecedented new window onto the cosmos.

This lecture is sponsored by the Center for Nonlinear Studies at Los Alamos National Laboratory, St. John’s College, Santa Fe Community College and the University of New Mexico. Diego Dalvit, Emil Mottola and Chris Fryer of Los Alamos, Carlton Caves and Dinesh Loomba of UNM, Eric Poppele of St. John’s College and Leonard Gannes of SFCC were on the organizing committee for this free public lecture.

About González

González became the spokesperson for the LIGO Scientific Collaboration in 2011. She completed her doctoral degree at Syracuse University in 1995 and worked as a staff scientist in the LIGO group at MIT until 1997, when she joined the faculty at Penn State University. In 2001, she joined the faculty at Louisiana State University.

González’s current research focuses on characterization of the LIGO detector noise, detector calibration and searching for gravitational waves in the data. In 2007, she was elected a fellow of the American Physical Society for her experimental contributions to the field of gravitational wave detection, for her leadership in the analysis of LIGO data for gravitational wave signals and for her skill in communicating physics to students and the public.

About Los Alamos National Laboratory

Los Alamos National Laboratory, a multidisciplinary research institution engaged in strategic science on behalf of national security, is operated by Los Alamos National Security, LLC, a team composed of Bechtel National, the University of California, BWXT Government Group, and URS, an AECOM company, for the Department of Energy’s National Nuclear Security Administration.

Los Alamos enhances national security by ensuring the safety and reliability of the U.S. nuclear stockpile, developing technologies to reduce threats from weapons of mass destruction, and solving problems related to energy, environment, infrastructure, health, and global security concerns.
