"Exploring the Extra-galactic Low Frequency Universe with MWA"

The Murchison Widefield Array is conducting an all-sky low-frequency radio survey across 70-230 MHz. The GaLactic and Extragalactic All-sky MWA (GLEAM) Survey comprises of over 300,000 catalogued components and represents a huge leap forward in our understanding of the low frequency radio sky. I will present the early science results from GLEAM probing the local to distance Universe. Highlights will include improved understanding of the star formationm of local star forming galaxies, searching for clusters at high redshift around radio-loud active galactic nuclei and searching for the first black holes. This work also has implications for the science from continuum surveys from SKA_LOW which may not be as confusion limited as previously feared.
