Enhanced Astrometry of the Rapid ASKAP Continuum Survey: Mid and High Frequency Epochs
Akhil Jaini, Adam T. Deller, Yuanming Wang +3
Accurate radio astrometry is essential for reliable cross-identification of sources across wavelengths, precision localisation of transient events, and the construction of stable a…
A FLASH HI absorption search in compact sources in the pilot ASKAP interplanetary scintillation field
Paris E. Gordon-Hall, Emily F. Kerrison, Elizabeth K. Mahony +13
The study uses ASKAP interplanetary scintillation measurements to identify compact radio sources and searches for redshifted HI 21 cm absorption between z = 0.4–1, detecting two ne…
One sightline, many systems: a FLASH discovery of HI towards scintillating quasar PKS 0405-385
E. F. Kerrison, H. Yoon, E. M. Sadler +15
We report the discovery of an intervening 21\,cm absorption line at z = 0.882 towards the z = 1.284 quasar PKS 0405-385, identified in the First Large Absorption Survey in HI (FLAS…
The First Large Absorption Survey in HI (FLASH): II. Pilot Survey data release and first results
Hyein Yoon, Elaine M. Sadler, Elizabeth K. Mahony +41
The First Large Absorption Survey in HI (FLASH) is a large-area radio survey for neutral hydrogen in the redshift range 0.4<z<1.0, using the 21cm HI absorption line as a probe of c…
The discovery of a 41s radio pulsar PSR J0311+1402 with ASKAP
Yuanming Wang, Pavan Uttarkar, Ryan Shannon +16
The emerging population of long-period radio transients (LPTs) show both similarities and differences with normal pulsars. A key difference is that their radio emission is too brig…
Enhanced Astrometry of the Rapid ASKAP Continuum Survey for Precise Localisation of Fast Radio Bursts
Akhil Jaini, Adam T. Deller, Yuanming Wang +2
Fast Radio Bursts (FRBs) are short, intense radio signals from distant astrophysical sources, and their accurate localisation is crucial for probing their origins and utilising the…
