Ordinary Meeting: Surveying the Southern Sky with the Anglo-Australian Telescope

Friday 7th July 2017 - 8:00pm
Topic:  Surveying the Southern Sky with the Anglo-Australian Telescope
Speaker: Dr. Angel Lopez-Sanchez, AAO
Venue: Epping Creative Centre - 26 Stanley Road, Epping
Abstract: The Anglo-Australian Telescope (AAT) plays a key role on the understanding of the Universe thanks to the powerful astronomy surveys it conducts. The AAT and its complex and unique instrumentation allows to massively collect data from stars to galaxies, and from exoplanets to quasars. These observations are fundamental to unravel the physics behind all these astronomical objects. In this talk I'll summarize the past, present and future of the AAT surveys, the main science results provided so far on these studies, as well as emphasize caution when reading astronomy news in media. For this I'll use the example of the confusion created in late 2016 when a small group of astronomers "claimed" that the expansion of the Universe is not accelerating, after the accelerated expansion was confirmed by independent studies, as those performed for the WiggleZ survey in 2009 using AAT data.
Biography:  I’m a Spanish astrophysicist working at the Australian Astronomical Observatory (AAO) and in the Department of Astronomy, Astrophysics and Astrophotonics of the Macquarie University (Sydney, NSW, Australia). My research in Astrophysics is focused in the analysis of star formation phenomena in galaxies of the local Universe, especially in dwarf starbursts and spiral galaxies, but using a multiwavelength approach.  I have recently taken on a new role role as the Science Communication Officer at the AAO. I got my Physics Degree at the University of Granada in 2000 and my PhD Thesis at the Instituto de Astrofísica de Canarias / La Laguna University (Tenerife, Spain) in 2006. Between 2007 and 2010 I worked at the CSIRO Astronomy and Space Science (Australia Telescope National Facility), obtaining many radio and optical data of galaxies of the Local Volume. Part of my actual job is providing support to the Anglo-Australian Telescope.  My passion for Astronomy actually started when I was a kid, in the mountain ranges near my natal city, Córdoba (Spain), when I became an active amateur astronomer.
