Mahony,Siddharth Malu,Marcella Massardi,Minnie Mao,Minnie Mao,David McConnell,Ray P. Norris,Dominic Schnitzeler,Ravi Subrahmanyan,James Urquhart,Mark Thompson,R. M. Wark +35 more
TL;DR: The Compact Array Broadband Backend (CABB) as discussed by the authors is an extension of the Australia Telescope Compact Array (ATCA) with 16-fold increase in observing bandwidth, from 2 x 128 MHz to 2 x 2048 MHz, high bit sampling, and addition of 16 zoom windows (each divided into a further 2048 channels) provide major improvements for all ATCA observations.

TL;DR: A large-scale survey of fast radio bursts—short pulses of radio waves that seem to come from cosmological distances—finds 20 events, including both the nearest and the most energetic bursts observed so far, and demonstrates that there is a relationship between burst dispersion and brightness.
