Detection of Two Massive CO Systems in 4C 41.17 at z = 3.8
Carlos De Breuck, Dennis Downes, Roberto Neri +4
We have detected CO(4-3) in the z=3.8 radio galaxy 4C 41.17 with the IRAM Interferometer. The CO is in two massive (M_dyn ~ 6 x 10^10 M_Sun) systems separated by 1.8" (13 kpc), and…
Atomic carbon in PSS 2322+1944, a quasar at redshift 4.12
J. Pety, A. Beelen, P. Cox +4
We report the detection of the 3P1 to 3P0 fine-structure line of neutral carbon in the z=4.12 quasar PSS 2322+1944, obtained at the IRAM Plateau de Bure interferometer. The CI 3P1-…
A Search for Dense Molecular Gas in High Redshift Infrared-Luminous Galaxies
C. L. Carilli, P. Solomon, P. Vanden Bout +8
We present a search for HCN emission from four high redshift far infrared (IR) luminous galaxies. Current data and models suggest that these high IR luminous galaxies represent…
Radio continuum imaging of FIR luminous QSOs at z>6
C. L. Carilli, F. Walter, F. Bertoldi +8
We present sensitive imaging at 1.4 GHz of the two highest redshift far-infrared (FIR) luminous QSOs SDSS J114816.65+525150.2 (z=6.42) and SDSS J104845.05+463718.3 (z=6.2). Radio c…
A multi-wavelength study of the proto-cluster surrounding the z=4.1 radio galaxy TN J1338-1942
Carlos De Breuck, Frank Bertoldi, Chris Carilli +8
We present a 1.2 mm (250 GHz) map obtained with MAMBO on the IRAM 30m telescope of the central 25 arcmin^2 of the proto-cluster surrounding the z=4.1 radio galaxy TN J1338-1942. Th…
Starburst activity in the host galaxy of the z=2.58 quasar J1409+5628
A. Beelen, P. Cox, J. Pety +6
We report the detection of CO emission from the optically luminous, radio-quiet quasar J140955.5+562827, at a redshift z_CO =2.583. We also present VLA continuum mapping results an…
