MIGHTEE: The Host-Galaxy Associated Catalogue of the Radio Sources in MIGHTEE Continuum Data Release 1
C. L. Hale, J. Hamlett, I. H. Whittam +34
Radio continuum surveys provide samples of active galactic nuclei (AGN) and star forming galaxies (SFGs) to high redshifts, free of biases due to dust obscuration. However, radio d…
The Radio-IR Correlation in the Context of Deep Radio Source Counts
Tirth D. Surti, Vikram Ravi, Allison Matthews +1
Increasingly deep, confusion-limited radio surveys have pushed direct radio source-count measurements down to tens of Jy at 1.4 GHz. Confusion-noise analyses extend the…
Resolved Maps of Gas and Dust in a Massive Quiescent Galaxy at z=2 from INQUEST-JWST: Evidence of Accretion and Rejuvenation
Sai Gangula, Andrew B. Newman, Meng Gu +10
Quiescent galaxies in the distant universe exhibit a range of gas content that may indicate a variety of quenching processes are at play. Mapping the distribution and kinematics of…
MIGHTEE: The evolving radio luminosity functions of star-forming galaxies to and the cosmic history of star formation
Nijin J. Thykkathu, Matt J. Jarvis, Imogen H. Whittam +9
A key question in extragalactic astronomy is how the star-formation rate density (SFRD) evolves over cosmic time. A powerful way of addressing this question is using radio-continuu…
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…
Probing the Infrared/Radio correlation of the full IRAS Revised Bright Galaxy Sample with MeerKAT and the VLA
M. E. Moloko, L. Marchetti, T. H. Jarrett +5
We study the infrared/radio correlation of galaxies in the IRAS Revised Bright Galaxy Sample using new MeerKAT observations at , complemented with VLA data. We c…
