MWA survey opens new window into the low-frequency radio sky

The Murchison Widefield Array (MWA) radio telescope has completed observations for a 2-year observing program to survey the entire radio sky accessible to the MWA. The GaLactic and Extragalactic All-sky MWA (GLEAM) survey was designed to meet the observational...

First year of Australia hunting for Black Holes and Dark Energy

Type Ia supernovae provided some of the first evidence for the accelerating Universe and remain among the most import tools for cosmology. The Dark Energy Survey (DES) Supernova Search is a new generation experiment that will discover more than 3000 Type Ia...

Escaping photons affect galaxy formation but supernovae dominant

The new generation of low-frequency radio telescopes, including MWA (Murchison Widefield Array), LOFAR (LOw Frequency Array), PAPER (Precision Array for Probing the Epoch of Reionisation) and SKA (Square Kilometre array), will enable us to observe the evolution of...

Pilot study data prepare astronomers for future blind HI surveys

Next-generation radio telescopes will make it possible to conduct the first large-scale HI absorption-line surveys, which will enable us to study the evolution of neutral gas in galaxies over a large range of cosmic time. However, we don’t currently have the...

Cosmic magnetic fields in ancient galaxies surprisingly strong

Magnetic fields influence the physics of exploding stars, galaxies, and even the cosmic large-scale structure. One of the most central questions is how they reached their current strength. It is believed that the amplification of galactic magnets happens through the...
