New CO detections of lensed submillimeter galaxies in A2218: Probing molecular gas in the LIRG regime at high redshift
K. K. Knudsen, R. Neri, J. -P. Kneib +1
Context: Submillimeter galaxies (SMGs) are distant, dusty galaxies undergoing star formation at prodigious rates. Recently there has been major progress in understanding the nature…
Interferometric CO Observations of submillimeter-faint, radio-selected starburst galaxies at z~2
S. C. Chapman, R. Neri, F. Bertoldi +9
High-redshift, dust-obscured galaxies -- selected to be luminous in the radio but relatively faint at 850um -- appear to represent a different population from the ultra-luminous su…
The dark nature of GRB 051022 and its host galaxy
A. J. Castro-Tirado, M. Bremer, S. McBreen +17
We present multiwavelength (X-ray/optical/near-infrared/millimetre) observations of GRB 051022 between 2.5 hours and ~1.15 yr after the event. It is the most intense gamma-ray burs…
Atomic Carbon in APM 08279+5255 at z=3.91
J. Wagg, D. J. Wilner, R. Neri +2
We present a detection of [CI] line emission in the lensed quasar APM 08279+5255 at z=3.91 using the IRAM Plateau de Bure interferometer. The [CI] line velocity and width are simil…
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…
High-excitation CO in a quasar host galaxy at z=6.42
F. Bertoldi, P. Cox, R. Neri +8
We report the detection of high excitation CO emission from the most distant quasar currently known, SDSS J114816.64+525150.3 (hereafter J1148+5251), at a redshift z=6.419. The CO…
