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…

SAGUI: SED-based Segmentation of Multi-band Galaxy Images -- Application to JADES in GOODS-South

Rafael S. de Souza, Andressa Wille, Shravya Shenoy +11

We present sagui, a modular framework for the analysis of multi-band imaging data in spatially resolved galaxies, with synergies to integral-field spectroscopy (IFS). Building on t…

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…

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…

A novel Bayesian approach for decomposing the radio emission of quasars: II. Link between quasar radio emission and black hole mass

B. -H. Yue, K. J. Duncan, P. N. Best +6

Whether the mass of supermassive black hole () is directly linked to the quasar radio luminosity remains a long-debated issue, and understanding the role of $M_\math…

The Host Galaxies of Radio AGN: New Views from Combining LoTSS and MaNGA Observations

Gaoxiang Jin, Guinevere Kauffmann, Philip N. Best +2

We utilize a combination of radio continuum observations and optical integral field spectroscopic (IFS) data to explore the impact of radio AGN on the evolution of their host galax…
