Feature Guests: David Hanna
Supernovae and hypernove, blazars and quasars: our universe is one exotic place. To help us to make sense of it, today we’re joined at The Star Spot by Professor David Hanna for an exploration of the zoo of the exotica as seen through the gamma ray universe.

What do satellites and whales have in common? Anuj explains. Then, Benjamin on how a fight over the reliability of atmospheric extrasolar planet discoveries is a triumph for a science without dogmas.
About Our Guest
David Hanna is an astrophysicist at McGill University in Montreal. He works in experimental high energy physics, everything from particle accelerators probing the physics of the very small to gamma ray astronomy studying the incredibly large. Hanna was a founding member of the US/Canada collaboration known as STACEE, the Solar Tower Atmospheric Cherenkov Effect Experiment. Yup, that’s why they call it STACEE. STACEE was an experiment dedicated to the study of high energy gamma rays emitted by astrophysical sources and was active observations until 2007.
He is currently a member of a new gamma ray collaboration called VERITAS which revels in its even longer name: the Very energetic radiation imaging telescope array system. Through his work in high energy physics, Hanna studies black holes at the centre of active galaxies, pulsars, gamma ray bursts, supernova remnants, dark matter, quasars, hypernova, supernova, unidentified sources.
