Avoiding dangerous climate change: Geo-engineering or mitigation? (Part 2)

Chiara talks to us about how timing the rotation of pulsars can be used to detect gravitational waves–ripples in the very fabric of the cosmos. Guest: Chiara Mingarelli (California Institute of Technology). Hosts: Erik Madsen and Chitrang Patel. Duration: 19 minutes. Production: James O’Callagh…

Enrico talks to us about the formation of heavy elements in the Universe through processes such as neutron star mergers. Guest: Enrico Ramirez-Ruiz (University of California Santa Cruz). Hosts: Robert Archibald and Chitrang Patel. Duration: 17 minutes. Production: James O’Callaghan.

We were visited by Dame Jocelyn Bell Burnell, who discovered pulsars during her graduate studies in the 1960s. She talks to us about the still highly active field of pulsar astronomy and her varied career since their discovery. We also discuss her tireless advocacy for women in physics and astronom…

We discussed how astronomers can studied cosmology, the formation and evolution of the Universe, by observing nearby dwarfs galaxies, instead of extremely distant galaxies at the edge of the Universe.
