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…
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…
Exploring the properties of the obscured hyperluminous quasar COS-87259 at z=6.853
Charalambia Varnava, Andreas Efstathiou, Duncan Farrah
In this paper we explore the properties of the z=6.853 obscured hyperluminous quasar COS-87259, discovered in the Cosmological Evolution Survey (COSMOS) field, with our recently de…
SMART: spectral energy distributions Markov chain analysis with radiative transfer models
Charalambia Varnava, Andreas Efstathiou
In this paper we present the publicly available open-source spectral energy distribution (SED) fitting code SMART (Spectral energy distributions Markov chain Analysis with Radiativ…
