Sungeun Kim,Lister Staveley-Smith,Michael A. Dopita,Kenneth C. Freeman,Robert J. Sault,Mike J. Kesteven,David McConnell +6 more
TL;DR: In this paper, an H I aperture synthesis mosaic of the Large Magellanic Cloud (LMC), made by combining data from 1344 separate pointing centers using the Australia Telescope Compact Array (ATCA), was presented.

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.

Fiona A. Harrison,J. S. Bloom,Dale A. Frail,Ramazan Sari,S. R. Kulkarni,S. G. Djorgovski,Tim Axelrod,Jeremy Mould,Brian P. Schmidt,M. H. Wieringa,R. M. Wark,Ravi Subrahmanyan,David McConnell,Patrick J. McCarthy,B. E. Schaefer,R. G. McMahon R. O. Markze,E. Firth,P. Soffitta,Lorenzo Amati +18 more
TL;DR: In this paper, the authors present multi-color optical and two-frequency radio observations of the bright SAX event, GRB 990510, and derive a jet opening angle of 0.08.
