We describe the scientific goals and survey design of the First Large Absorption Survey in HI (FLASH), a wide field survey for 21-cm line absorption in neutral atomic hydrogen (HI)…
81 New Candidate Fast Radio Bursts in Parkes Archive
X. Yang, S. -B. Zhang, J. -S. Wang +14
We have searched for weak fast radio burst (FRB) events using a database containing 568,736,756 transient events detected using the Parkes radio telescope between 1997 and 2001. In…
The Atomic Hydrogen Content of Galaxies as a function of Group-Centric Radius
Wenkai Hu, Luca Cortese, Lister Staveley-Smith +5
We apply a spectral stacking technique to Westerbork Synthesis Radio Telescope observations to measure the neutral atomic hydrogen content (HI) of nearby galaxies in and around gal…
WALLABY Pre-Pilot Survey: The effects of angular momentum and environment on the HI gas and star formation properties of galaxies in the Eridanus supergroup
C. Murugeshan, V. A. Kilborn, B. -Q. For +17
We use high-resolution ASKAP observations of galaxies in the Eridanus supergroup to study their HI, angular momentum and star formation properties, as part of the WALLABY pre-pilot…
WALLABY pre-pilot survey: Two dark clouds in the vicinity of NGC 1395
O. Ivy Wong, A. R. H. Stevens, B. -Q. For +34
We present the Australian Square Kilometre Array Pathfinder (ASKAP) WALLABY pre-pilot observations of two `dark' HI sources (with HI masses of a few times 10^8 Msol and no known st…
