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-r…
