Planck 2013 results. IX. HFI spectral response
Kneissl, R.; Miville-Deschênes, M. -A.; Boulanger, F. +217 more
The Planck High Frequency Instrument (HFI) spectral response was determined through a series of ground based tests conducted with the HFI focal plane in a cryogenic environment prior to launch. The main goal of the spectral transmission tests was to measure the relative spectral response (includingthe level of out-of-band signal rejection) of all …
Planck 2013 results. XXVIII. The Planck Catalogue of Compact Sources
Kneissl, R.; Miville-Deschênes, M. -A.; Bernard, J. -P. +241 more
The Planck Catalogue of Compact Sources (PCCS) is the catalogue of sources detected in the first 15 months of Planck operations, the “nominal” mission. It consists of nine single-frequency catalogues of compact sources, both Galactic and extragalactic, detected over the entire sky. The PCCS covers the frequency range 30-857 GHz with higher sensiti…
Planck 2013 results. XIII. Galactic CO emission
Miville-Deschênes, M. -A.; Boulanger, F.; Bernard, J. -P. +241 more
Rotational transition lines of CO play a major role in molecular radio astronomy as a mass tracer and in particular in the study of star formation and Galactic structure. Although a wealth of data exists for the Galactic plane and some well-known molecular clouds, there is no available high sensitivity all-sky survey of CO emission to date. Such a…
Planck 2013 results. XIX. The integrated Sachs-Wolfe effect
Miville-Deschênes, M. -A.; Bernard, J. -P.; Planck Collaboration +245 more
Based on cosmic microwave background (CMB) maps from the 2013 Planck Mission data release, this paper presents the detection of the integrated Sachs-Wolfe (ISW) effect, that is, the correlation between the CMB and large-scale evolving gravitational potentials. The significance of detection ranges from 2 to 4σ, depending on which method is used. We…
Planck 2013 results. XXI. Power spectrum and high-order statistics of the Planck all-sky Compton parameter map
Kneissl, R.; Miville-Deschênes, M. -A.; Bernard, J. -P. +236 more
We have constructed the first all-sky map of the thermal Sunyaev-Zeldovich (tSZ) effect by applying specifically tailored component separation algorithms to the 100 to 857 GHz frequency channel maps from the Planck survey. This map shows an obvious galaxy cluster tSZ signal that is well matched with blindly detected clusters in the Planck SZ catal…
Herschel-Planck dust optical-depth and column-density maps. I. Method description and results for Orion
Alves, João; Bouy, Hervé; Lada, Charles J. +1 more
We present high-resolution, high dynamic range column-density and color-temperature maps of the Orion complex using a combination of Planck dust-emission maps, Herschel dust-emission maps, and 2MASS NIR dust-extinction maps. The column-density maps combine the robustness of the 2MASS NIR extinction maps with the resolution and coverage of the Hers…
Properties of z ~ 3-6 Lyman break galaxies. II. Impact of nebular emission at high redshift
Schaerer, D.; Stark, D. P.; de Barros, S.
Context. To gain insight on the mass assembly and place constraints on the star formation history (SFH) of Lyman break galaxies (LBGs), it is important to accurately determine their properties.
Aims: We estimate how nebular emission and different SFHs affect parameter estimation of LBGs.
Methods: We present a homogeneous, detailed analys…
Dust spectral energy distributions of nearby galaxies: an insight from the Herschel Reference Survey
Ciesla, L.; Buat, V.; Boquien, M. +20 more
Although it accounts only for a small fraction of the baryonic mass, dust has a profound impact on the physical processes at play in galaxies. Thus, to understand the evolution of galaxies, it is essential not only to characterize dust properties per se, but also in relation to global galaxy properties. To do so, we derive the dust properties of g…
Planck intermediate results. XVII. Emission of dust in the diffuse interstellar medium from the far-infrared to microwave frequencies
Kneissl, R.; Miville-Deschênes, M. -A.; Boulanger, F. +195 more
The dust-Hi correlation is used to characterize the emission properties of dust in the diffuse interstellar medium (ISM) from far infrared wavelengths to microwave frequencies. The field of this investigation encompasses the part of the southern sky best suited to study the cosmic infrared and microwave backgrounds. We cross-correlate sky maps fro…
Disk evolution in the solar neighborhood. I. Disk frequencies from 1 to 100 Myr
Bouy, Hervé; Merín, Bruno; Ribas, Álvaro +1 more
Aims: We study the evolution of circumstellar disks in 22 young (1 to 100 Myr) nearby (within 500 pc) associations over the entire mass spectrum using photometry covering from the optical to the mid-infrared.
Methods: We compiled a catalog of 2340 spectroscopically-confirmed members of these nearby associations. We analyzed their spectra…
