Year-timescale changes in AGN radio luminosity as seen by the ASKAP Variables and Slow Transients Survey
Chloe Klare, Charlotte Ward, Dougal Dobie +6
A few dozen previously radio-quiet active galactic nuclei (AGN) have been observed to transition to radio-loud at 1-3 GHz frequencies over timescales of more than a decade, and thi…

The birth of young radio jets in changing-look AGN: a population study
Sufia Birmingham, Charlotte Ward, Kristina Nyland +4
Changing-Look Active Galactic Nuclei (CLAGN) are a rare subset of AGN that show significant changes to the flux of broad Balmer emission lines. Recent studies of CLAGN, such as 1ES…

Disentangling transients and their host galaxies with Scarlet2: A framework to forward model multi-epoch imaging
Charlotte Ward, Peter Melchior, Matt L. Sampson +6
Many science cases for wide-field time-domain surveys rely on accurate identification and characterization of the galaxies hosting transient and variable objects. In the era of the…
