ICRAR’s research staff form the backbone of our activities in astronomy, engineering and data intensive astronomy.
They work across our many projects in areas as varied as telescope systems design and verification, large scale simulations of the Universe, and the overwhelming computing systems required for the next generation of telescopes and galaxy surveys.

All about the galaxy life cycle
Dr Davies looks at galaxies of all shapes and sizes to compare those that existed in the early Universe to those that formed more recently.
Luke’s big research question at the moment is ‘do galaxies form more stars when they dramatically smash together?’
Research Specialisation: Galaxy evolution by comparing the stellar, dust and molecular gas components of star-forming systems in the early Universe.

I am reasearcher at CIRA (Curtin Institute of Radio Astronomy), working on galaxy evolution. More particularly, I focus on the co-evolution active galatic nuclei (AGN) emitting at radio wavelengths in the early Universe. My main interest is to understand how the central supermassive black hole at the center of the AGN formed, evolved and influenced the formation and evolution of the most massive galaxies observed in the local Universe.
I also work on gravitationally amplified galaxies. Thanks to a massive structure (galaxy or galaxy cluster) located on the line of sight of distant galaxies, fainter background galaxies are magnified, both in power and resolution. Thanks to this natural boost, we are able to probe scales otherwise unobservable, even with our most powerful telescopes, and understand the star formation properties in the peak of the activity in the young Universe.

Building Synthetic Universes
Dr. Pascal uses simulations of cosmic structure formation as laboratories to test theories of galaxy formation, dark matter, dark energy and gravity.
Pascal uses his virtual laboratories to answer two big questions. How to galaxies, such as our own Milky Way, form and evolve? What makes up the invisible part of our Universe, that is what is dark matter and what is dark energy?

I like the Moon!
I am leading an exciting to project to study the very early Universe using the Moon and the Murchison Widefield Array telescope in Western Australia. I’m hoping to measure low-frequency radio waves emitted by Hydrogen during the period when the first stars and galaxies where forming. Why boring old Hydrogen you ask? Because that is what most of the Universe was in those days and it can tell us all sorts of things about how the Universe got from being small, hot and smooth to being the big, cool, clumpy thing it is today.
I’m also interested in these strange, powerful objects dotted throughout the universe known as radio galaxies. In particular, I like to study the ones that are close-by in our cosmic neighbourhood, as we can see them in exquisite detail using a wide range of different instruments, from radio telescopes, to optical telescopes to X-ray and gamma-ray observatories in space! The things we learn from these close-by objects can be be applied to our simulations of the early Universe, helping us to eventually put together the whole cosmic puzzle of where we came from and where we are going.
If you are interested in any of this stuff, feel free to get in touch!

I am a research associate with the Centre of Excellence for All-Sky Astrophysics (CAASTRO). After finishing my PhD at UWA in 2015, which concerned statistical and computational analyses of dark matter haloes, I moved to Curtin where I am a part of the Epoch of Reionisation (EoR) team, using the MWA to attempt to detect the faint signals of the first stars and galaxies.
My role in this team is primarily statistical. Detection of the EoR is an incredibly ambitious undertaking. Not only is the signal extremely faint, but between it and us is basically every galaxy and star in the Universe. These intervening objects obscure and distort the signal we are trying to detect, and so to unravel their impact requires sophisticated statistical machinery. My job is to provide some of that machinery, so that one day we can hope to extract that all-important signal.

Danail Obreschkow has a passion for many fields in modern astrophysics and cosmology. His core areas of research include galaxy evolution, star formation, as well as cosmic large-scale structure. His research style mixes computational, analytical and observational methods, having supervised research students using all these methods. Over the last decade, Danail developed new models of for the evolution of cold gas in galaxies, highly relevant to modern observations and future surveys on the Square Kilometre Array telescope. More recently, Danail and his collaborators made fundamental discoveries on the connection between galactic angular momentum and the internal physics of galaxies; and his team also demonstrated the use of new statistical tools to extract information about the cosmos from the large-scale distribution of galaxies in space.

My research focuses on accreting black holes, where I use multiwavelength space- and ground-based observations to study acrcretion over the full range of black hole masses (from stellar to supermassive) and accretion rates (from quiescent to super-Eddington). My main research goal is to better understand the structure/geometry of accretion flows (and their outflows) in different accretion regimes, in order to more effectively use radiation as a probe of Galactic and extragalactic black hole populations, and to learn how black holes may impact their large-scale environments.

Attila is a radio astronomer working on large neutral hydrogen surveys. These surveys image the gas content of many galaxies in large cosmological volumes. As neutral hydrogen gas is the basic element in the Universe, these surveys play a crucial role in helping to understand the evolution of galaxies.
Because of the large data-volumes of modern radio surveys, Attila is interested in data intensive astronomy and he is working on the development of automated reduction pipelines.

I am a computational astrophysicist working on a broad range of problems in galaxy formation and cosmology. My particular interests are in dark matter – what is its nature? what kinds of observations will allow us to discriminate between alternative models? – and in how feedback from stars and black holes (i.e. deposition of energy and momentum into their surroundings) impact the formation and evolution of galaxies. Most of this work requires powerful supercomputers, and so I also have an ongoing interest in scientific high performance computing.
I obtained a BA in Theoretical Physics from Trinity College Dublin in 1999, and a PhD from Durham University in 2003. Between 2004 and 2011, I held postdoc positions in the Swinburne Centre for Astrophysics and Supercomputing in Melbourne (2004-07) and with the Theoretical Astrophysics Group at the University of Leicester (2008-11). I have been at ICRAR/UWA since 2011, initially as a research assistant professor and, since 2014, as a research associate professor and ARC Future Fellow. Here at ICRAR/UWA, I lead the Computational Theory and Modelling Group, a team of approximately 20 staff, postdocs and students working on a variety of simulation, modelling, and statistical problems in galaxy formation and cosmology.
I am an associate member of the ARC Centre of Excellence for All-Sky Astrophysics (CAASTRO), and am a Chief Investigator for the new ARC CoE CAASTRO3D. I also serve on various committees, including the Astronomical Society of Australia council, the Australia Telescope Time Assignment Committee (TAC), the Astronomy Supercomputer Time Allocation Committee (ASTAC), and the Australian e-Research Advisory Committee (AeRAC).
