I am currently Project Scientist for the Wide Area VISTA Extragalactic Survey (WAVES) which is a survey designed to understand the evolution of galaxies and the structure of the Universe over the last 8 billion years by measuring the properties of 2 Million galaxies. WAVES is being undertaken using the new 4m Multi Object Spectroscopic Telescope as part of the 4MOST consortium (4MOST), of which I am lead of the extragalactic analysis pipeline working group, and member of the science coordination board.
Here you can see the layout of the WAVES surveys and regions we will cover. WAVES-wide will cover the whole of the KiDs/VIKING regions to a total of ~1350deg2 and will target galaxies out to z<0.2. While WAVES-deep will cover two 50deg2 regions in KiDs-South to align with exisiting and upcoming multi-wavelength surveys (the left figure is produced using out online tool, AstroMap): WAVES Layout
WAVES will also compile and extensive multi-wavelength database, combining data from many different facilities coving a broad range of the EM spectrum to probe multiple physical properties of galaxies: WAVES facilities
I am also Principle Investigator for the Deep Extragalactic VIsible Legacy Survey (DEVILS), spectroscopic survey of ~70,000 galaxies designed to measure the evolution of the large scale structure of the Universe and the galaxies that reside within in.
The survey is currently being undertaken by the Anglo-Australain Telescope in New South Wales. I am the Principle Investigator of this project, which means I am responsible for leading and international team of over 50 researchers who are working on science using the DEVILS data.
If you’d like to learn more about DEVILS, see here.
In addition, I am deputy lead of the ASKAP Evolutionary Map of the Universe (EMU) key science project to explore the cosmic evolution of star-fromation, an active member of the Galaxy And Mass Assembly (GAMA) survey, COSMOS HI Large Extragalactic Survey (CHILES) and Deep Investigations of Neutral Gas Origins (DINGO) survey.
My research is primarily focused on how galaxies have changed from the Big Bang to the present day and aims to answer key questions about the Universe such as, how did the first groups of stars come together to form galaxies, how do galaxies change as the Universe expands over time and how do we eventually form galaxies like our own Milky Way? In order to do this I use observations from some of the world’s most powerful telescopes to study the light emitted from young galaxies, which formed when the Universe was just a fraction of its current age. I then compare these galaxies with the more massive, more complicated and older galaxies, which reside in the Universe today and try piece together links between these seemingly unconnected types of galaxy.
For more information on me and my research see here.
I am also an active contributor to the ICRAR outreach program giving schools talks, TV and Radio interviews, and producing educational videos. For a few examples of my outreach work, see here.
Lastly, I have produced a number of tools to aid astronomers, which can be accessed via the ICRAR site here.
