Scientists have recently developed a new way to 'see' the universe, using gravitational waves predicted by Einstein over a century ago. These waves can teach us about some of the most exotic objects known, including black holes and neutron stars - objects which are very difficult to observe with conventional light-gathering telescopes, but are prodigious emitters of gravitational waves. Remarkably, they have also helped solve a longstanding puzzle about where in the Universe some of the elements we know and love here on Earth are produced, including gold, platinum, and uranium.  Eliot Quataert will describe the exciting and remarkable new results coming out of our first steps into the gravitational wave era.

Eliot Quataert is a Professor of Astrophysical Sciences and the Charles A. Young Professor of Astronomy at Princeton University. Quataert is an astrophysics theorist who works on a wide range of problems, including stars and black holes, plasma astrophysics, and how galaxies form. He has received a number of national awards for his research, including the Warner Prize of the AAS, the Packard Fellowship, a Simons Investigator award from the Simons Foundation, and elected membership in the American Academy of Arts and Sciences and the National Academy of Sciences. Quataert is also a highly regarded teacher and public lecturer.

Quartaert was born in Santa Monica, California, lived for almost 12 years in Houston, Texas, and spent his high school years in Vestal, New York (upstate near the border between NY and PA).  He received his B.S. in Physics from MIT in 1995 and a Ph.D. in Astronomy from Harvard University in 1999.   He was a postdoc in the School of Natural Sciences at the Institute for Advanced Study for 2 years before joining the faculty at UC-Berkeley in 2001.  He moved to Princeton in Fall 2020.

Founded in 1997 and named in honor of Distinguished Professor Emeritus Icko Iben Jr., the Icko Iben Jr. Distinguished Lecture Series brings a noted astronomer to campus to highlight some of the latest developments in astronomy in a forum geared for the general public.
