The FAST HI 21-cm Absorption Blind Survey. III. OH Absorption Search in the 21-cm Absorber Sample and Continued HI Absorption Search
Wenkai Hu, Yougang Wang, Jeremy Darling +11
We present the first blind search for OH 18-cm absorption with the Five-hundred-meter Aperture Spherical Telescope (FAST), conducted alongside the HI 21-cm absorption search. Our p…
Low-Frequency Recombination Lines from Galaxies and AGN over Cosmic Time
Kimberly L. Emig, Sergei Balashev, Francoise Combes +10
Radio recombination lines (RRLs) at low frequencies (<10 GHz) can provide a multi-phase view of interstellar gas in nearby galaxies, absorption-line-systems, and AGN. Hydrogen RRLs…
Tracing Cold Gas in Absorption Across Cosmic Time with the SKA
Elizabeth K. Mahony, Neeraj Gupta, Sergei A. Balashev +12
Observing the 21-cm HI line in absorption provides a powerful means of tracing the cold neutral gas in normal and active galaxies across cosmic time. The frequency coverage and sen…
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…
RadioSED II: discovering the peaked spectrum radio sources in Stripe 82
E. F. Kerrison, E. M. Sadler, V. A. Moss +6
This paper is the second in a series presenting \textsc{RadioSED}, a Bayesian inference framework for constructing, modelling and classifying radio spectral energy distributions fr…
A FLASH on Blazars: Capturing the Radio Realm of 4FGL Blazars with SKAO Pathfinders
Meriem Behiri, Elizabeth Mahony, Elaine Sadler +6
This work investigates the multi-wavelength properties of 165 4FGL blazars from the Fermi-LAT fourth source catalogue, looking for with counterparts in the Australian SKA Pathfinde…
