The DESI View of the Faint Radio Source Population in LoTSS DR2
M. I. Arnaudova, L. R. Holden, D. J. B. Smith +10
The faint radio-source population includes galaxies dominated by both star formation (SF) and active galactic nuclei (AGN), which are two key processes shaping galaxy evolution. To…
Dust destruction signals shock-accelerated outflows in the nearby active galaxy NGC 1068
Luke R. Holden, Clive N. Tadhunter, Daniel J. B. Smith +3
Massive gas outflows driven by active galactic nuclei (AGN) are a key ingredient in models of galaxy evolution, in which they are required to regulate star formation and thus expla…
Unlocking the Full Potential of SKAO Extra-galactic Science with High-multiplex Optical Spectroscopy
Kenneth J Duncan, Natasha Maddox, Daniel J. B Smith +9
Parallel to the transformation in radio continuum and H I observations from SKAO pathfinders and precursors over the past decade has been the development of a new generation of mul…
The dependence of triggering mechanisms on radio AGN sub-types: the role of galaxy mergers
Freya Barwell, Clive N. Tadhunter, Jonathon C. S. Pierce +10
Powerful, radio-loud active galactic nuclei (AGN) are associated with one of the most important forms of AGN feedback, and understanding how they are triggered is key to properly i…
What factors shape the radio luminosity of star-forming galaxies? A new calibration from LoTSS-DR2
Shravya Shenoy, Daniel J. B. Smith, Sarah K. Biddle +8
Radio observations offer a dust-unobscured view of galaxy star formation via the radio continuum-star formation rate (RC--SFR) relation. Emerging evidence of a stellar mass depende…
Electron densities from [S II] lines significantly overestimate the impact of ionised AGN outflows
Luke R. Holden, Daniel J. B. Smith, Marina I. Arnaudova +6
To explain the properties of the local galaxy population, theoretical models require active galactic nuclei (AGN) to inject energy into host galaxies, thereby expelling outflows of…
