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…

The effect of extended radio emission on SMBH accretion rate estimates

Stergios Amarantidis, Duncan Farrah, Nick Seymour +5

Accretion rates in radio galaxies are typically estimated from optical and total radio flux measurements, incorporating emission from the core, jets, and lobes. These estimates can…

The role of environment in triggering AGN -- evidence for a change at 1

Jason Reeves, Anna Sajina, Henry Adair +2

What triggers AGN in some galaxies and what role does this brief period of activity play in the overall evolution of galaxies are still open questions. This paper explores whether…

Halfway to the Peak: ice absorption bands at with JWST MIRI/MRS

Anna Sajina, Alexandra Pope, Henrik Spoon +9

This paper presents the first combined detections of CO, CO, XCN and water ices beyond the local Universe. We find gas-phase CO in addition to the solid phase CO. Our source, S…

Angular Sizes of Jy Radio Sources

W. D. Cotton, J. J. Condon, K. I. Kellermann +6

We made two new sensitive (rms noise sigma_n ~ 1 microJy/beam) high resolution (theta = 3.0" and theta = 0.66" FWHM) S--band (2 < nu < 4 GHz) images covering a single JVLA primary…

The Spitzer mid-infrared AGN survey. I - optical and near-infrared spectroscopy of candidate obscured and normal AGN selected in the mid-infrared

M. Lacy, S. E. Ridgway, E. L. Gates +8

We present the results of a program of optical and near-infrared spectroscopic follow-up of candidate Active Galactic Nuclei (AGN) selected in the mid-infrared. This survey selects…

The stellar, molecular gas and dust content of the host galaxies of two z~2.8 dust obscured quasars

Mark Lacy, Andreea O. Petric, Alejo Martinez-Sansigre +4

We present optical through radio observations of the host galaxies of two dust obscured, luminous quasars selected in the mid-infrared, at z=2.62 and z=2.99, including a search for…

Radio-quiet quasar environments at 0.5 < z < 0.8

M. Wold, M. Lacy, P. B. Lilje +1

We have quantified the galaxy environments around a sample of 0.5 < z < 0.8 radio-quiet quasars using the amplitude of the spatial galaxy--quasar correlation function, B_gq. The qu…

A search for molecular gas in high redshift radio galaxies

R. van Ojik, H. J. A. Röttgering, P. P. van der Werf +8

We present results of an extensive search for molecular gas in 14 high redshift () radio galaxies. Radio galaxies with redshifts between 2.0 and 4.3 were observed during sever…
