An artist's impression of a relativistic jet propagating away from a black hole at close to the speed of light. Such jets are formed by the inner regions of the accretion flow: matter flowing inwards towards the black hole, via processes which are not yet fully understood. The accretion flow emits primarily in X-rays, the relativistic jet in the radio band: by combing observations in each band we can try and understand how such jets form and how much energy they carry away from the black hole.

Black holes in the Universe - Astronomy for All Lecture
 

Wednesday 10 May 2023   

18:00 to 19:00, a virtual event hosted by Green Templeton College.
 

Speaker: Professor Rob Fender, Head of Astrophysics, University of Oxford

Black holes, conceived as mathematical possibilities centuries ago, are now established as an astrophysical reality: over 100 million black holes reside within our galaxy alone. Consisting of a singularity, where current theories of physics break down, and surrounded by an event horizon, from within which no signal can ever escape, they are quite unlike anything else in the Universe. Yet despite their mysterious nature, in the past two decades extraordinary observational breakthroughs in understanding black holes have been made. In this lecture, the speaker will present these breakthroughs, and discuss what lies ahead in the coming decades and centuries.

 

About the speaker

Rob Fender is Head of Astrophysics at the Department of Physics at University of Oxford. His research focuses on observations of accretion and relativistic jet formation around black holes. He led the national collaboration via which the UK joined the LOFAR project, was awarded in 2011 an ERC Advanced Investigator Grant and in 2022 an ERC Synergy Grant, and amongst other prizes was awarded the 2020 Herschel Medal of the Royal Astronomical Society for ‘investigations of outstanding merit in observational astrophysics’.
