The applicability of far-infrared fine-structure lines as star formation rate tracers over wide ranges of metallicities and galaxy types
Lebouteiller, Vianney; De Looze, Ilse; Baes, Maarten +19 more
Aims: We analyze the applicability of far-infrared fine-structure lines [Cii] 158 µm, [Oi] 63 µm, and [Oiii] 88 µm to reliably trace the star formation rate (SFR) in a sample of low-metallicity dwarf galaxies from the Herschel Dwarf Galaxy Survey and, furthermore, extend the analysis to a broad sample of galaxies of various …
Planck 2013 results. XXX. Cosmic infrared background measurements and implications for star formation
Kneissl, R.; Miville-Deschênes, M. -A.; Boulanger, F. +239 more
We present new measurements of cosmic infrared background (CIB) anisotropies using Planck. Combining HFI data with IRAS, the angular auto- and cross-frequency power spectrum is measured from 143 to 3000 GHz, and the auto-bispectrum from 217 to 545 GHz. The total areas used to compute the CIB power spectrum and bispectrum are about 2240 and 4400 de…
The evolution of the dust and gas content in galaxies
Berta, S.; Magnelli, B.; Nordon, R. +36 more
We use deep Herschel observations taken with both PACS and SPIRE imaging cameras to estimate the dust mass of a sample of galaxies extracted from the GOODS-S, GOODS-N and the COSMOS fields. We divide the redshift-stellar mass (Mstar)-star formation rate (SFR) parameter space into small bins and investigate average properties over this g…
The evolution of the dust temperatures of galaxies in the SFR-M∗ plane up to z ∼ 2
Berta, S.; Magnelli, B.; Nordon, R. +38 more
We study the evolution of the dust temperature of galaxies in the SFR- M∗ plane up to z ~ 2 using far-infrared and submillimetre observations from the Herschel Space Observatory taken as part of the PACS Evolutionary Probe (PEP) and Herschel Multi-tiered Extragalactic Survey (HerMES) guaranteed time key programmes. Starting from a sampl…
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…
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…
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…
An excess of dusty starbursts related to the Spiderweb galaxy
Altieri, B.; Sanchez-Portal, M.; Valtchanov, I. +16 more
We present APEX LABOCA 870 µm observations of the field around the high-redshift radio galaxy MRC1138-262 at z = 2.16. We detect 16 submillimeter galaxies (SMGs) in this ~140 arcmin2 bolometer map with flux densities in the range 3-11 mJy. The raw number counts indicate a density of SMGs that is up to four times that of blank fiel…
A Herschel [C ii] Galactic plane survey. II. CO-dark H2 in clouds
Goldsmith, P. F.; Langer, W. D.; Pineda, J. L. +2 more
Context. H i and CO large scale surveys of the Milky Way trace the diffuse atomic clouds and the dense shielded regions of molecular hydrogen clouds, respectively. However, until recently, we have not had spectrally resolved C+ surveys in sufficient lines of sight to characterize the ionized and photon dominated components of the inters…
Reconstructing the density and temperature structure of prestellar cores from Herschel data: A case study for B68 and L1689B
Abergel, A.; Hill, T.; Roussel, H. +22 more
Utilizing multiwavelength dust emission maps acquired with Herschel, we reconstruct local volume density and dust temperature profiles for the prestellar cores B68 and L1689B using an inverse-Abel transform-based technique. We present intrinsic radial dust temperature profiles of starless cores directly from dust continuum emission maps disentangl…
