Lurking in the Darkness: Intermediate Mass Black Holes in Low-Mass Galaxies

By Daniel Bartels • June 19th, 2015

The Milky Way is surrounded by a swarm of tens of lower mass satellite galaxies, the properties of which challenge the predictions of supercomputer simulations of galaxy formation. In this project we focus on the so-called “Too Big To Fail” (TBTF) problem — the prediction that the most massive dark matter subhaloes, which should hostmore…

Galactic star formation regulated by interstellar dust

By Daniel Bartels • February 18th, 2015

Interstellar dust is a fundamentally important component of interstellar medium (ISM) in galaxies. The main reason for this is that it can control interstellar chemistry of variously different elements on dust grains and thereby drive the formation of molecular hydrogen from which new stars can form in galaxies. In this project, we try to elucidatemore…

Detection of Spectral Lines with MWA

By Daniel Bartels • February 18th, 2015

MWA is a radio interferometer with a unique property – high surface brightness and high spacial resolution at the same time. This makes it an ideal instrument for studying the diffuse emission of galactic gas in radio recombination lines (RRL). This signal is faint and generally very difficult to observe. We have observed a widemore…

A combination of ICRAR Data Intensive Astronomy and SKA Science Data Processor projects

By david satterthwaite • February 18th, 2015

The data intensive nature of the SKA Science Data Processor (SDP) calls for a data driven compute architecture which aims at exploiting data parallelism and data locality. ICRAR is leading the respective SDP data layer task, which is an international collaboration within the SDP consortium, and responsible for developing a credible design in the contextmore…
