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
In this pilot study, we use data from the First Large Absorption Survey in HI (FLASH) to search for redshifted HI 21cm absorption at towards 157 bright radio sources with…
SDSSJ110546.07+145202.4: The first long-duration radio changing-look NLS1 galaxy
S. Komossa, D. Grupe, A. Kraus +12
SDSSJ110546.07+145202.4 stands out as a unique radio changing-look Narrow-line Seyfert 1 (NLS1) galaxy that has brightened dramatically and shows an exceptionally long duration of…
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…
findAbar: how astronomers may perceive the bar in galaxies differently
Elizabeth J. Iles, Joss Bland-Hawthorn, Courtney Crawford +18
Bars are ubiquitous morphological features in the observed distribution of galaxies. There are similarly many methods for classifying these features and, without a strict theoretic…
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…
VLBI studies of FLASH H I 21-cm absorbers -- I
J. N. H. S. Aditya, Elaine M. Sadler, Raffaella Morganti +9
We have conducted VLBA 1.4 GHz (L-band) continuum observations towards twelve sources with HI 21-cm absorption detections at redshift in the pilot surveys of FLASH, an…
ALMACAL XIV: X-Shooter Spectroscopy, Infrared Properties and Radio SEDs of Calibrators
Simon Weng, Elaine M. Sadler, Emily Kerrison +8
The ALMACAL-22 survey includes over 2700 hours of observations of ALMA phase and amplitude calibrators, spanning frequencies from 84 to 950 GHz across bands 3 to 10. In total, 687…
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…
From terrestrial weather to space weather through the history of scintillation
Emily F. Kerrison, Ron D. Ekers, John Morgan +1
Recent observations of interplanetary scintillation (IPS) at radio frequencies have proved to be a powerful tool for probing the solar environment from the ground. But how far back…
Why so young? A curious connection between the broadband flux and neutral gas content of AGN
Emily F. Kerrison, Elaine M. Sadler, Vanessa A. Moss +1
We present here a study of the broadband spectral properties of 33 sources detected in HI absorption as part of the ASKAP-FLASH Pilot Surveys. We outline our approach to spectral c…
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…
RadioSED I: Bayesian inference of radio SEDs from inhomogeneous surveys
Emily F. Kerrison, James R. Allison, Vanessa A. Moss +2
We present here RadioSED, a Bayesian inference framework tailored to modelling and classifying broadband radio spectral energy distributions (SEDs) using only data from publicly-re…
The highest mass Kepler red giants -- I. Global asteroseismic parameters of 48 stars
Courtney L. Crawford, Timothy R. Bedding, Yaguang Li +6
When low- and intermediate-mass stars evolve off the main sequence, they expand and cool into the red giant stages of evolution, which include those associated with shell H burning…
The FLASH pilot survey: an HI absorption search against MRC 1-Jy radio sources
