JWST observations and a model for the extremely luminous obscured quasar W2246-0526 at z=4.6
Charalambia Varnava, Andreas Efstathiou, Tanio DÃaz-Santos +1
We present new JWST/MIRI-MRS data of the z=4.601 extremely luminous obscured quasar WISEA J224607.56-052634.9 (W2246-0526). Our fits of its spectral energy distribution (SED) with…
The undetectable fraction of core-collapse supernovae in luminous infrared galaxies -- II. GSAOI/GeMS dataset
I. Mäntynen, E. Kankare, S. Mattila +7
Core-collapse supernovae (CCSNe) in luminous infrared galaxies (LIRGs) can have extreme line-of-sight host galaxy dust extinctions, which leads to a large fraction of the events re…
Calibrating Mid-Infrared Emission Features As Diagnostics of Star Formation in Infrared-Luminous Galaxies via Radiative Transfer Modeling
L. Robinson, D. Farrah, A. Efstathiou +13
Luminous infrared galaxies are key sites of obscured stellar mass assembly at z > 0.5. Their star formation rates (SFRs) are often estimated using the luminosities of the 6.2 micro…
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…
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…
