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…

Role of SKA in Advancing Remote Measurements of Magnetic Fields of Solar Coronal Mass Ejections

Devojyoti Kansabanik, Surajit Mondal, Shaheda Begum Shaik +13

Coronal Mass Ejections (CMEs) are large expulsions of magnetized plasma from the Sun into interplanetary space and are the primary drivers of extreme space weather variations. The…

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 ASKAP-FLASH survey: A first look at the multiwavelength properties and redshift distribution of compact radio sources

W. Roster, E. M. Sadler, E. K. Mahony +15

We present the characterisation, including a photometric redshift (photo-) analysis, of the optical counterparts (CTPs) to over 45 000 bright ( 30 mJy) comp…
