Topic: Gravitational Waves from Merging Black Holes and Neutron Stars
With guest speaker: Associate Professor Jan J. Eldridge, Head of Department, Physics, University of Auckland

In 2015 the first detection of two merging black holes was detected by the LIGO gravitational wave observatories. While these "ripples in spacetime" were predicted by Einstein in 1915 it took a century to build an instrument sensitive enough to detect them. I'll outline how gravitational waves are observed and the sources we see in the Universe and what we have learnt about black holes. I'll also describe what we've learnt from the events including neutron stars.
