The SKA - world's biggest telescope (Free Range Science from RiAus)

Professor Steven Tingay visited Bendigo in Victoria as part of RiAus's Free Range Science. He gave a presentation on the SKA and Australia's work towards it and the RiAus were kind enough to share the presentation online for all of us.

OWLS Fly Through

This is a fly through of a cosmological simulation that has been converted into what a radio telescope such as ASKAP will see.
We start the movie at low frequency, which means a large distance away (redshifting by the Universes expansion shifts the ~1.4 GHz neutral hydrogen line to lower frequencies). The Declination (y-axis) is the 'up-down' axis on the sky and Right Ascension (x-axis) is the 'left-right' measure on the horizon. The field of view in this telescope is 10 square degrees.

The red dots are galaxies and the broad green distributions are of the cosmic web that lies between the galaxies and clusters of galaxies.

The top left panel is the original particle distribution from the simulation, with red colours indicating a strong signal, and blue a weaker signal.
The top right panel is after smoothing the particles in frequency due to thermal broadening. As gas has a temperature individual atoms will move in random directions which will emit HI at different blue/red-shifted frequencies (giving an overall broadening of the signal in frequency).
The bottom right panel takes these particles and smoothes them in space using the smoothing kernel from the simulation, corrected for the projection map of this radio observation.
The bottom left panel is the final step in creating a mock observation by smoothing the datacube with the actual beam of the telescope (seen as a small black circle in the bottom left). This represents the actual observation that a telescope would see.

The HI Universe: (Neutral hydrogen galaxy simulation fly through)

Starting from 25 h^-1 Mpc across we see the column density of Neutral Hydrogen - HI (as detectable by radio telescopes such as ASKAP).
The broad filaments of low density HI (in purple) is the Cosmic Web and traces the underlying Dark Matter distribution. At the nodes of theweb are cluster of galaxies, one of which we zoom in on.
The final galaxy we can see is of a galaxy about the size of our Milky Way (10^12 Msol) but when the Universe was only a few billion years old, making it truly a monster galaxy at this point in time. The blobs of cold material (green) are falling into the central disk, which is of very high density (seen in red). Galaxy formation at this early time was an active and dynamically complex process.
The simulation zooms out again showing that this galaxy is but a tiny part of the much larger picture.
