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…

A JWST Paschen-alpha Calibration of the Radio Luminosity-Star Formation Rate Relation at z~1.3

Nick Seymour, Catherine Hale, Imogen Whittam +17

As radio emission from normal galaxies is a dust-free tracer of star formation, tracing the star formation history of the Universe is a key goal of the SKA and ngVLA. In order to i…

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…

MIGHTEE: exploring the relationship between spectral index, redshift and radio luminosity

Siddhant Pinjarkar, Martin J. Hardcastle, Dharam V. Lal +9

It has been known for many years that there is an apparent trend for the spectral index (α) of radio sources to steepen with redshift z, which has led to attempts to select high-re…

Unveiling AGN Outflows: [O iii] Outflow Detection Rates and Correlation with Low-Frequency Radio Emission

Emmy L. Escott, Leah K. Morabito, Jan Scholtz +10

Some Active Galactic Nuclei (AGN) host outflows which have the potential to alter the host galaxy's evolution (AGN feedback). These outflows have been linked to enhanced radio emis…

Radio-AGN activity across the galaxy population: dependence on stellar mass, star-formation rate, and redshift

R. Kondapally, P. N. Best, K. J. Duncan +16

We characterise the co-evolution of radio-loud AGN and their galaxies by mapping the dependence of radio-loud AGN activity on stellar mass and star-formation rate (SFR) across cosm…

The Radio Galaxy Environment Reference Survey (RAGERS): a submillimetre study of the environments of massive radio-quiet galaxies at

Thomas M. Cornish, Julie L. Wardlow, Thomas R. Greve +15

Measuring the environments of massive galaxies at high redshift is crucial to understanding galaxy evolution and the conditions that gave rise to the distribution of matter we see…
