ABSTRACT: From Baby Planets to Black Holes - ALMA and the Event Horizon Telescope

 

For the first time ever, humanity has imaged one of these elusive cosmic beasts, shining light on an exotic space-time realm that had long been beyond our ken. No single telescope on Earth can make that observation; the Event Horizon Telescope (EHT) links submillimetre wave radio telescopes in Arizona, Spain, Mexico, Chile, Antarctica and other places around the world, forming a virtual instrument the size of Earth.  Key to the EHT is the Atacama Large Millimetre/Submillimetre wave Array (ALMA) Observatory, a billion dollar multi-national astronomy facility of which Canada is a partner, located at high elevation in the Atacama desert of northern Chile.  Its 66 antennas work together as if one giant telescope 16 km in diameter, to give us unprecedented images of the cold, dark universe, including the birth of planets around other stars, organic molecules in the early universe, and when combined with telescopes around the world as part of the EHT, the first image of the event horizon of the super-massive black hole at the heart of the M87 galaxy.  Gerald will talk about ALMA and the EHT, what it’s like to work there, and some of the astonishing discoveries being made by this facility.
