The Roman eXtreme Deep Field (RXDF)
Haojing Yan, Anton M. Koekemoer, Yue Shen +127
The Roman eXtreme Deep Field (RXDF) program is one of the five General Astrophysics Survey (GAS) programs approved for observing time with the Nancy Grace Roman Space Telescope in…
JWST observations and a model for the extremely luminous obscured quasar W2246-0526 at z=4.6
Charalambia Varnava, Andreas Efstathiou, Tanio Díaz-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…
A comparative study of galaxy evolution with four different active galactic nucleus torus models and two different host geometries
Michail Papadopoulos, Vicky Papadopoulou Lesta, Ioannis Michos +2
Estimating physical quantities such as the star formation rate, stellar mass and active galactic nucleus (AGN) fraction of galaxies is a key step in understanding galaxy formation…
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…
Tracing obscured galaxy build-up at high redshift using deep radio surveys
Stergios Amarantidis, Jose Afonso, Israel Matute +5
A fundamental question of extra-galactic astronomy that is yet to be fully understood, concerns the evolution of the star formation rate (SFR) and supermassive black hole (SMBH) ac…
Optical integral field spectroscopy of intermediate redshift infrared bright galaxies
M. Pereira-Santaella, D. Rigopoulou, G. E. Magdis +10
The extreme infrared (IR) luminosity of local luminous and ultra-luminous IR galaxies (U/LIRGs; 11 < log LIR /Lsun < 12 and log LIR /Lsun > 12, respectively) is mainly powered by s…
NuSTAR observations of Mrk 766: distinguishing reflection from absorption
D. J. K. Buisson, M. L. Parker, E. Kara +14
We present two new NuSTAR observations of the narrow line Seyfert 1 (NLS1) galaxy Mrk 766 and give constraints on the two scenarios previously proposed to explain its spectrum and…
Main sequence of star forming galaxies beyond the Herschel confusion limit
W. J. Pearson, L. Wang, P. D. Hurley +7
Deep far-infrared (FIR) cosmological surveys are known to be affected by source confusion, causing issues when examining the main sequence (MS) of star forming galaxies. This has t…
