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…
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…
Probing the co-evolution of SMBHs and their hosts from scaling relations pairwise residuals: dominance of stellar velocity dispersion and host halo mass
Francesco Shankar, Mariangela Bernardi, Daniel Roberts +17
The correlations between Supermassive Black Holes (SMBHs) and their host galaxies still defy our understanding from both the observational and theoretical perspectives. Here we per…
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…
The assembly of supermassive black holes at in early-type galaxies from scaling relations
Duncan Farrah, Athena Engholm, Evanthia Hatziminaoglou +14
The assembly of supermassive black hole (SMBH) mass () and stellar mass () in galaxies can be studied via the redshift evolution of the rela…
