Observations and modelling of a clumpy galaxy at z=1.6: Spectroscopic clues to the origin and evolution of chain galaxies
F. Bournaud, E. Daddi, B. G. Elmegreen +7
We investigate the properties of a clump-cluster galaxy at redshift 1.57. The morphology of this galaxy is dominated by eight star-forming clumps in optical observations, and has p…
IRAC Excess in Distant Star-Forming Galaxies: Tentative Evidence for the 3.3m Polycyclic Aromatic Hydrocarbon Feature ?
B. Magnelli, R. R. Chary, A. Pope +3
We present evidence for the existence of an IRAC excess in the spectral energy distribution (SED) of 5 galaxies at 0.6<z<0.9 and 1 galaxy at z=1.7. These 6 galaxies, located in the…
Reliable Identification of Compton-thick Quasars at z~2: Spitzer Mid-IR spectroscopy of HDF-oMD49
D. M. Alexander, R. R. Chary, A. Pope +6
Many models that seek to explain the origin of the unresolved X-ray background predict that Compton-thick Active Galactic Nuclei (AGNs) are ubiquitious at high redshift. However, f…
Vigorous star formation with low efficiency in massive disk galaxies at z=1.5
E. Daddi, H. Dannerbauer, D. Elbaz +4
We present the first detection of molecular gas cooling CO emission lines from ordinary massive galaxies at z=1.5. Two sources were observed with the IRAM Plateau de Bure Interfero…
Multiwavelength study of massive galaxies at z~2. II. Widespread Compton thick AGN and the concurrent growth of black holes and bulges
E. Daddi, D. M. Alexander, M. Dickinson +16
Approximately 20-30% of 1.4<z<2.5 galaxies with K<22 (Vega) detected with Spitzer MIPS at 24um show excess mid-IR emission relative to that expected based on the rates of star form…
Report by the ESA-ESO Working Group on "The Herschel-ALMA Synergies"
T. L. Wilson, D. Elbaz, eds
The Herschel Satellite and the Atacama Large Millimeter Array (ALMA) are two very large sub-mm and far infrared (FIR) astronomy projects that are expected to come into operation in…
