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…
Witnessing the violent, merger-driven formation of an extremely massive galaxy 1.7 Gyr after the Big Bang
Lura K. Pitchford, Joseph Cairns, Duncan Farrah +4
We combine near-infrared imaging in two bands from the Hubble Space Telescope (HST) with archival observations of molecular gas to study SDSS J160705.16+533558.6 (J1607), an extrem…
An ALMA Band 7 survey of SDSS/Herschel quasars in Stripe 82: I. The properties of the 870 micron counterparts
E. Hatziminaoglou, H. Messias, R. Souza +6
(Abridged) Quasar studies with Herschel/SPIRE often report host luminosities ranging from 10^{12} to 10^{14} Lsun, suggestive of star formation rates (SFRs) of up to several thousa…
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…
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…
Observational evidence for cosmological coupling of black holes and its implications for an astrophysical source of dark energy
Duncan Farrah, Kevin S. Croker, Gregory Tarlé +16
Observations have found black holes spanning ten orders of magnitude in mass across most of cosmic history. The Kerr black hole solution is however provisional as its behavior at i…
A Preferential Growth Channel for Supermassive Black Holes in Elliptical Galaxies at z<2
Duncan Farrah, Sara Petty, Kevin Croker +12
The assembly of stellar and supermassive black hole (SMBH) mass in elliptical galaxies since can help to diagnose the origins of locally-observed correlations between SMBH…
Stellar and black hole assembly in z<0.3 infrared-luminous mergers: intermittent starbursts vs. super-Eddington accretion
Duncan Farrah, Andreas Efstathiou, Jose Afonso +20
We study stellar and black hole mass assembly in a sample of 42 infrared-luminous galaxy mergers at z<0.3 by combining results from radiative transfer modelling with archival measu…
Consistent analysis of the AGN LF in X-ray and MIR in the XMM-LSS field
Jack Runburg, Duncan Farrah, Anna Sajina +9
The luminosity function (LF) of active galactic nuclei (AGN) probes the history of supermassive black hole assembly and growth across cosmic time. To mitigate selection biases, we…
The mid-infrared and CO gas properties of an extreme star-forming FeLoBAL quasar
Lura K. Pitchford, Duncan Farrah, Katherine Alatalo +6
We present a detailed study of a high-redshift iron low-ionization broad absorption line (FeLoBAL) quasar (SDSS1214 at ), including new interferometric CO =2-1…
