Behind the scenes at the AAT with Dr Andy Green

Friday 15th April 2016 - 8:00pm
Topic:  Behind the scenes at the AAT: A new mirror every year and other shenanigans
Speaker:  Dr Andy Green, AAO
Venue: Epping Creative Centre - 26 Stanley Road, Epping
Abstract: How do you clean a very precise, highly polished mirror surrounded by expensive electronics without damaging anything? At the AAT, the staff actually replace the thin film of aluminium that makes the 4 metre primary mirror of the telescope, and they do it every year. The process brings together heavy industry and high-precision optics, and keeps the AAT at the forefront of astronomy. But this isn’t the only difficult task at the AAT—there are innumerable complex industrial and technical challenges that must be overcome to make sure the telescope is ready for research every night of the year.
Biography: Andy Green is a research astronomer at the Australian Astronomical Observatory. He received his PhD in Astronomy from Swinburne in Melbourne, and his Bachelor of Science in Astrophysics from Caltech in California. Andy studies the kinematics of star forming galaxies in an effort to better understand how galaxies such as our own form and evolve. At the Observatory, he helps design, build and maintain astronomical instruments, and helps other astronomers use those instruments. Andy is also a keen outdoors person.
