Vela seen on 132 modules at Molonglo

Vela is the brightest Southern hemisphere pulsar, and thus very important for testing the UTMOST upgrade at Molonglo.



The image shows Vela being detected on 132 of the 352 Molonglo modules — with the characteristic bright sweep seen in most of these modules being the “dispersion”, or delay in the pulse arrival time as a function of frequency, caused the pulse traversing hte ionised Interstellar Medium. Each postage stamp image shows Vela’s pulses as detected in each  module as a function of frequency and time.
