Halfway to the Peak: Kinematic Signatures of Stable Rotating Disks in Luminous Infrared Galaxies at z=0.5-0.6

Miriam Eleazer, Alexandra Pope, Anna Sajina +13

We present a kinematic study of six infrared-luminous galaxies observed with the Mid-InfraRed Instrument Medium-Resolution Spectrometer (MIRI/MRS) onboard JWST. These galaxies lie…

Extended Radio Galaxies in EMU: A Comparative Look at Source-Finding Techniques

Lachlan J. Barnes, Andrew M. Hopkins, Yjan Gordon +8

Extended radio sources present unique challenges for automated detection and classification in wide-field radio surveys. With current surveys such as the Evolutionary Map of the Un…

EMU/GAMA: Refining Dust Extinction Corrections for Hα Luminosity Functions Using Radio-Based Calibration

J. Willingham, A. Hopkins, T. Zafar +17

We present a novel approach to correcting H luminosity functions for dust extinction by calibrating against radio-based star formation rates (SFRs), using data from the Evoluti…

The effect of extended radio emission on SMBH accretion rate estimates

Stergios Amarantidis, Duncan Farrah, Nick Seymour +5

Accretion rates in radio galaxies are typically estimated from optical and total radio flux measurements, incorporating emission from the core, jets, and lobes. These estimates can…

The role of environment in triggering AGN -- evidence for a change at 1

Jason Reeves, Anna Sajina, Henry Adair +2

What triggers AGN in some galaxies and what role does this brief period of activity play in the overall evolution of galaxies are still open questions. This paper explores whether…

The Compton-thick AGN Population and the Distribution of Low-mass AGN in our Cosmic Backyard

A. Annuar, D. M. Alexander, P. Gandhi +21

We present a census of the Compton-thick (CT) active galactic nucleus (AGN) population and the column density () distribution of AGN in our cosmic backyard using a mid-…
