TL;DR: The Parkes Pulsar Timing Array (PPTA) as mentioned in this paper is an implementation of the PTA concept based on observations with the Parkes 64m radio telescope, which allows investigation of 'global' phenomena such as a background of gravitational waves or instabilities in atomic timescales that produce correlated timing residuals in the pulsars of the array.

TL;DR: The Boolardy test array as discussed by the authors is a prototype of the Australian square kilometre array pathfinder telescope with a six-antenna interferometer, fitted with prototype signal processing hardware capable of forming at least nine dual-polarisation beams simultaneously.

TL;DR: The Parkes pulsar data archive as discussed by the authors provides access to 144044 data files obtained from observations carried out at the Parkes observatory since the year 1991, around 105 files are from surveys of the sky, the remainder are observations of 775 individual pulsars and their corresponding calibration signals.

TL;DR: In this paper, the authors report the discovery of a 21-cm H I absorption system using commissioning data from the Boolardy Engineering Test Array of the Australian Square Kilometre Array Pathfinder (ASKAP).

TL;DR: The Boolardy Engineering Test Array (BETA) as discussed by the authors is the first aperture synthesis radio telescope to use phased array feed technology, giving it the ability to electronically form up to nine dual-polarisation beams.
