The 154 MHz radio sky observed by the Murchison Widefield Array: noise, confusion, and first source count analyses

The 154 MHz radio sky observed by the Murchison Widefield Array: noise, confusion, and first source count analyses

We analyse a 154 MHz image made from a 12 h observation with the Murchison Widefield Array (MWA) to determine the noise contribution and behaviour of the source counts down to 30 mJy. The MWA image has a bandwidth of 30.72 MHz, a field-of-view within the half-power contour of the …
