"Fast Radio Bursts: Astronomical Puzzle and Cosmic Probe”


Roger Blandford, Stanford, KIPAC, Professor Particle Physics and Astrophysics

For over a decade, radio astronomers have been observing millisecond pulses of intense radio emission from across the universe. They invited explanations from alien signals to microwave ovens.

It now seems quite likely that they are created by flares or quakes on neutron stars with magnetic fields that are a million, billion times as strong as that on earth. These extreme conditions stretch our understanding of physics. In this talk, Dr. Blandford will explain why this is now the leading interpretation, and how, independent of their origin. Fast Radio Bursts (FRBs) are becoming wonderful probes of the universe at large.

Brief Bio

Roger Blandford took his BA, MA and PhD degrees at Cambridge University. Following postdoctoral research at Cambridge, Princeton and Berkeley he took up a faculty position at Caltech in 1976 where he was appointed as the Richard Chace Tolman Professor of Theoretical Astrophysics in 1989.

In 2003, he moved to Stanford University to become the first Director of the Kavli Institute for Particle Astrophysics and Cosmology and the Luke Blossom Chair in the School of Humanities and Science. His research interests include black hole astrophysics, cosmology, gravitational lensing, cosmic ray physics and compact stars.

He is a Fellow of the Royal Society, the American Academy of Arts and Sciences, the American Physical Society and a Member of the National Academy of Sciences. In 2008-2010, he chaired a two year National Academy of Sciences Decadal Survey of Astronomy and Astrophysics.

Dr. Blandford was awarded the 1998 Dannie Heineman Prize of the American Astronomical Society, the 2013 Gold Medal of the Royal Astronomical Society, the 2016 Crafoord Prize for Astronomy and the 2020 Shaw Prize for Astronomy.
