Deblending the MIGHTEE-COSMOS survey with XID+: The resolved radio source counts to Jy

Eliab D. Malefahlo, Matt J. Jarvis, Mario G. Santos +9

Deep radio continuum surveys provide fundamental constraints on galaxy evolution, but source confusion limits sensitivity to the faintest sources. We present a complete framework f…

Tracing AGN-Galaxy Co-Evolution with UV Line-Selected Obscured AGN

Luigi Barchiesi, Lucia Marchetti, Mattia Vaccari +11

Understanding black hole-galaxy co-evolution and the role of AGN feedback requires complete AGN samples, including heavily obscured systems. In this work, we present the first UV l…

COSMOS Spectroscopic Redshift Compilation (First Data Release): 488k Redshifts Encompassing Two Decades of Spectroscopy

Ali Ahmad Khostovan, Jeyhan S. Kartaltepe, Mara Salvato +54

We present the COSMOS Spectroscopic Redshift Compilation encompassing ~ 20 years of spectroscopic redshifts within a 10 deg area centered on the 2 deg COSMOS legacy field.…

Machine Learning Approaches for Classifying Star-Forming Galaxies and Active Galactic Nuclei from MIGHTEE-Detected Radio Sources in the COSMOS Field

Walter Silima, Fangxia An, Mattia Vaccari +2

Radio synchrotron emission originates from both massive star formation and black hole accretion, two processes that drive galaxy evolution. Efficient classification of sources domi…

Semi-empirical constraints on the HI mass function of star-forming galaxies and at from interferometric surveys

Francesco Sinigaglia, Alessandro Bianchetti, Giulia Rodighiero +5

The HI mass function is a crucial tool to understand the evolution of the HI content in galaxies over cosmic times. We aim to derive semi-empirical constraints at by c…

The Evolutionary Map of the Universe: A new radio atlas for the southern hemisphere sky

A. M. Hopkins, A. Kapinska, J. Marvil +70

We present the Evolutionary Map of the Universe (EMU) survey conducted with the Australian Square Kilometre Array Pathfinder (ASKAP). EMU aims to deliver the touchstone radio atlas…
