How accurately can obscured galaxy luminosities be measured using spectral energy distribution fitting of near- through far-infrared observations?

Duncan Farrah, Kiana Ejercito, Andreas Efstathiou +23

Infrared-luminous galaxies are important sites of stellar and black hole mass assembly at most redshifts. Their luminosities are often estimated by fitting spectral energy distribu…

GATOS. VIII. On the physical origin of the extended MIR emission in AGN

Enrique Lopez-Rodriguez, Cristina Ramos Almeida, Miguel Pereira-Santaella +31

The polar mid-infrared (MIR) emission detected within 10-100s pcs in some active galactic nuclei (AGN) has been associated with dusty winds driven away by radiation pressure. The p…

Theoretical Diagnostics for the Physical Conditions in Active Galactic Nuclei under the View of JWST

Lulu Zhang, Ric I. Davies, Chris Packham +20

With excellent spectral and angular resolutions and, especially, sensitivity, the JWST allows us to observe infrared emission lines that were previously inaccessible or barely acce…

A Census of the Most Obscured Galaxy Nuclei over Cosmic Time to be revealed by PRIMA

Fergus R. Donnan, Dimitra Rigopoulou, Ismael García-Bernete +2

Characterizing the growth of supermassive Black Holes (SMBHs) is critical to the evolution of galaxies, however the majority of this activity is obscured, rendering traditional tra…

Constraints on the active galactic nucleus and starburst activity of local ultraluminous infrared galaxies from a broad range of torus models

Charalambia Varnava, Andreas Efstathiou, Duncan Farrah +1

In this paper we further explore the properties of the HERschel Ultra Luminous Infrared Galaxy Survey (HERUS) sample of 42 local ultraluminous infrared galaxies (ULIRGs) with our r…

Molecular Gas Heating, Star Formation Rate Relations, and AGN Feedback in Infrared-luminous Galaxy Mergers

Duncan Farrah, Andreas Efstathiou, Jose Afonso +13

We examine the origin of molecular gas heating in a sample of 42 infrared-luminous galaxies at by combining two sets of archival data. First, integrated CO line luminositie…
