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…
The LOFAR Two-metre Sky Survey Deep Fields: new probabilistic spectroscopic classifications and the accretion rates of radio galaxies
M. I. Arnaudova, D. J. B. Smith, M. J. Hardcastle +8
The faint radio-source population includes sources dominated both by star formation and active galactic nuclei (AGN), encoding the evolution of activity in the Universe. To investi…
No evidence for fast, galaxy-wide ionised outflows in a nearby quasar -- the importance of accounting for beam smearing
Luke R. Holden, Clive N. Tadhunter
To test the scenario that outflows accelerated by active galactic nuclei (AGN) have a major impact on galaxy-wide scales, we have analysed deep VLT/MUSE data for the type-2 quasar/…
QSOFEED: The relationship between star formation and AGN Feedback
Patricia S. Bessiere, Cristina Ramos Almeida, Luke R. Holden +2
Large-scale cosmological simulations suggest that feedback from active galactic nuclei (AGN) plays a crucial role in galaxy evolution. In this study, we directly test this hypothes…
ALMA reveals a compact and massive molecular outflow driven by the young AGN in a nearby ULIRG
Luke R. Holden, Clive N. Tadhunter, Anelise Audibert +5
The ultra luminous infrared galaxy (ULIRG) F13451+1232 is an excellent example of a galaxy merger in the early stages of active galactic nucleus (AGN) activity, a phase in which AG…
Outflow densities and ionisation mechanisms in the NLRs of the prototypical Seyfert galaxies NGC 1068 and NGC 4151
Luke R. Holden, Clive N. Tadhunter
Despite being thought to play an important role in galaxy evolution, the true impact of outflows driven by active galactic nuclei (AGN) on their host galaxies is unclear. In part,…
Precise physical conditions for the warm gas outflows in the nearby active galaxy IC 5063
Luke R. Holden, Clive N. Tadhunter, Raffaella Morganti +1
AGN-driven outflows are now routinely used in models of galaxy evolution as a feedback mechanism, however many of their properties remain highly uncertain. Perhaps the greatest sou…
