We investigate the relation between star formation rates (Ṁs) and AGN properties in optically selected type 1 quasars at 2 < z < 3 using data from Herschel and the SDSS. We find that Ṁs remains approximately constant with redshift, at 300± 100M yr−1. Conversely, Ṁs increases with AGN luminosity, up to a maximum of ∼600M yr−1, and with C IV FWHM. In context(More)
We present 20 Wide-field Infrared Survey Explorer (WISE )-selected galaxies with bolometric luminosities Lbol > 10 14 L , including five with infrared luminosities LIR ≡ L(rest 8−1000μm) > 10 L . These “extremely luminous infrared galaxies,” or ELIRGs, were discovered using the “W1W2dropout” selection criteria (Eisenhardt et al. 2012) which requires(More)
Wepresent SCUBA-2 (Submillimetre Common-User Bolometer Array) 850μmsubmillimetre (submm) observations of the fields of 10 dusty, luminous galaxies at z ∼ 1.7–4.6, detected at 12 and/or 22μm by the Wide-field Infrared Survey Explorer (WISE) all-sky survey, but faint or undetected at 3.4 and 4.6μm; dubbed hot, dust-obscured galaxies (Hot DOGs). The six(More)
Few patients survive transection of the aorta caused by blunt trauma. However, among those who do are a small number who go on to live with an unrecognized pseudoaneurysm that may rupture at any time. Because these aneurysms may be mistaken for more common disease processes, such as hilar adenopathy, atherosclerotic aneurysm, or neoplasia, the authors(More)
We study the geometry of the active galactic nucleus (AGN) obscurer in IRAS 09104+4109, an IR-luminous, radio-intermediate FR-I source at z = 0.442, using infrared data from Spitzer and Herschel, X-ray data from NuSTAR, Swift, Suzaku, and Chandra, and an optical spectrum from Palomar. The infrared data imply a total restframe 1–1000 μm luminosity of(More)
We present WISE All-Sky mid-infrared (IR) survey detections of 55% (17/31) of the known QSOs at z > 6 from a range of surveys: the SDSS, the CFHT-LS, FIRST, Spitzer and UKIDSS. The WISE catalog thus provides a substantial increase in the quantity of IR data available for these sources: 17 are detected in the WISE W1 (3.4μm) band, 16 in W2 (4.6μm), 3 in W3(More)
The rest-frame far-ultraviolet (FUV) morphologies of 8 nearby interacting and starburst galaxies (Arp 269, M 82, Mrk 8, NGC 520, NGC 1068, NGC 3079, NGC 3310, & NGC 7673) are compared with 54 galaxies at z∼ 1.5 and 46 galaxies at z∼ 4 observed in the Great Observatories Origins Deep Survey (GOODS) taken with the Advanced Camera for Surveys onboard the(More)
We investigate the relation between star formation rates (Ṁs) and AGN properties in optically selected type 1 quasars at 2 < z < 3 using data from Herschel and the SDSS. We find that Ṁs remains approximately constant with redshift, at 300±100 M⊙yr. Conversely, Ṁs increases with AGN luminosity, up to a maximum of ∼ 600 M⊙yr, and with C iv FWHM. In context(More)

We report a new technique to select 1.6 ∼ z < ∼ 4.6 dusty Lyman-alpha emitters (LAEs), over a third of which are ‘blobs’ (LABs) with emission extended on scales of 30-100kpc. Combining data from the NASA Wide-field Infrared Survey Explorer (WISE) mission with optical spectroscopy from the W.M.Keck telescope, we present a color criteria that yields a 78%(More)
