GOODS-Herschel: an infrared main sequence for star-forming galaxies
Magnelli, B.; Lutz, D.; Altieri, B. +52 more
We present the deepest 100 to 500 µm far-infrared observations obtained with the Herschel Space Observatory as part of the GOODS-Herschel key program, and examine the infrared (IR) 3-500 µm spectral energy distributions (SEDs) of galaxies at 0 < z < 2.5, supplemented by a local reference sample from IRAS, ISO, Spitzer, and AKARI …
Characterizing interstellar filaments with Herschel in IC 5146
Hill, T.; André, Ph.; Arzoumanian, D. +21 more
We provide a first look at the results of the Herschel Gould Belt survey toward the IC 5146 molecular cloud and present a preliminary analysis of the filamentary structure in this region. The column density map, derived from our 70-500 µm Herschel data, reveals a complex network of filaments and confirms that these filaments are the main bir…
The MCXC: a meta-catalogue of x-ray detected clusters of galaxies
Arnaud, M.; Pointecouteau, E.; Pratt, G. W. +2 more
We present the compilation and properties of a meta-catalogue of X-ray detected clusters of galaxies, the MCXC. This very large catalogue is based on publicly available ROSAT All Sky Survey-based (NORAS, REFLEX, BCS, SGP, NEP, MACS, and CIZA) and serendipitous (160SD, 400SD, SHARC, WARPS, and EMSS) cluster catalogues. Data have been systematically…
Planck early results. I. The Planck mission
Kneissl, R.; Miville-Deschênes, M. -A.; Bernard, J. -P. +272 more
The European Space Agency's Planck satellite was launched on 14 May 2009, and has been surveying the sky stably and continuously since 13 August 2009. Its performance is well in line with expectations, and it will continue to gather scientific data until the end of its cryogenic lifetime. We give an overview of the history of Planck in its first y…
PACS Evolutionary Probe (PEP) - A Herschel key program
Berta, S.; Magnelli, B.; Nordon, R. +35 more
Deep far-infrared photometric surveys studying galaxy evolution and the nature of the cosmic infrared background are a key strength of the Herschel mission. We describe the scientific motivation for the PACS Evolutionary Probe (PEP) guaranteed time key program and its role within the entire set of Herschel surveys, and the field selection that inc…
Planck early results. VIII. The all-sky early Sunyaev-Zeldovich cluster sample
Kneissl, R.; Dahle, H.; Miville-Deschênes, M. -A. +235 more
We present the first all-sky sample of galaxy clusters detected blindly by the Planck satellite through the Sunyaev-Zeldovich (SZ) effect from its six highest frequencies. This early SZ (ESZ) sample is comprised of 189 candidates, which have a high signal-to-noise ratio ranging from 6 to 29. Its high reliability (purity above 95%) is further ensur…
Estimation of the XUV radiation onto close planets and their evaporation
Eiroa, C.; Ribas, I.; Solano, E. +5 more
Context. The current distribution of planet mass vs. incident stellar X-ray flux supports the idea that photoevaporation of the atmosphere may take place in close-in planets. Integrated effects have to be accounted for. A proper calculation of the mass loss rate through photoevaporation requires the estimation of the total irradiation from the who…
Planck early results. XIX. All-sky temperature and dust optical depth from Planck and IRAS. Constraints on the "dark gas" in our Galaxy
Kneissl, R.; Miville-Deschênes, M. -A.; Boulanger, F. +205 more
An all sky map of the apparent temperature and optical depth of thermal dust emission is constructed using the Planck-HFI (350µm to 2 mm) andIRAS(100µm) data. The optical depth maps are correlated with tracers of the atomic (Hi) and molecular gas traced by CO. The correlation with the column density of observed gas is linear in the low…
The global dust SED: tracing the nature and evolution of dust with DustEM
Boulanger, F.; Bernard, J. -P.; Le Bourlot, J. +6 more
The Planck and Herschel missions are currently measuring the far-infrared to millimeter emission of dust, which combined with existing IR data, will for the first time provide the full spectral energy distribution (SED) of the galactic interstellar medium dust emission, from the mid-IR to the mm range, with an unprecedented sensitivity and down to…
Evolution of the dusty infrared luminosity function from z = 0 to z = 2.3 using observations from Spitzer
Magnelli, B.; Elbaz, D.; Frayer, D. T. +4 more
Aims: We derive the evolution of the infrared luminosity function (LF) over the last 4/5ths of cosmic time using deep 24 and 70 µm imaging of the GOODS North and South fields.
Methods: We use an extraction technique based on prior source positions at shorter wavelengths to build the 24 and 70 µm source catalogs. The majority …
