Molecular line emission in NGC 1068 imaged with ALMA. I. An AGN-driven outflow in the dense molecular gas
Tacconi, L. J.; Hunt, L. K.; Colina, L. +23 more
Aims: We investigate the fueling and the feedback of star formation and nuclear activity in
Methods: We have used the A…
The frequency of planetary debris around young white dwarfs
Gänsicke, B. T.; Koester, D.; Farihi, J.
Context. Heavy metals in the atmospheres of white dwarfs are thought in many cases to be accreted from a circumstellar debris disk, which was formed by the tidal disruption of a rocky planetary body within the Roche radius of the star. The abundance analysis of photospheric elements and conclusions about the chemical composition of the accreted ma…
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. XXV. Searches for cosmic strings and other topological defects
Miville-Deschênes, M. -A.; Bernard, J. -P.; Planck Collaboration +225 more
Planck data have been used to provide stringent new constraints on cosmic strings and other defects. We describe forecasts of the CMB power spectrum induced by cosmic strings, calculating these from network models and simulations using line-of-sight Boltzmann solvers. We have studied Nambu-Goto cosmic strings, as well as field theory strings for w…
Planck 2013 results. XII. Diffuse component separation
Kneissl, R.; Miville-Deschênes, M. -A.; Boulanger, F. +258 more
Planck has produced detailed all-sky observations over nine frequency bands between 30 and 857 GHz. These observations allow robust reconstruction of the primordial cosmic microwave background (CMB) temperature fluctuations over nearly the full sky, as well as new constraints on Galactic foregrounds, including thermal dust and line emission from m…
Gaia FGK benchmark stars: Metallicity
Montes, D.; de Laverny, P.; Cantat-Gaudin, T. +22 more
Context. To calibrate automatic pipelines that determine atmospheric parameters of stars, one needs a sample of stars, or "benchmark stars", with well-defined parameters to be used as a reference.
Aims: We provide detailed documentation of the iron abundance determination of the 34 FGK-type benchmark stars that are selected to be the pillars …
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…
Planck 2013 results. XXVII. Doppler boosting of the CMB: Eppur si muove
Bernard, J. -P.; Planck Collaboration; Aghanim, N. +181 more
Our velocity relative to the rest frame of the cosmic microwave background (CMB) generates a dipole temperature anisotropy on the sky which has been well measured for more than 30 years, and has an accepted amplitude of v/c = 1.23 × 10-3, or v = 369. In addition to this signal generated by Doppler boosting of the CMB monopole, our motio…
The Sloan Digital Sky Survey quasar catalog: tenth data release
Finley, Hayley; Pâris, Isabelle; Petitjean, Patrick +47 more
We present the Data Release 10 Quasar (DR10Q) catalog from the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey III. The catalog includes all BOSS objects that were targeted as quasar candidates during the first 2.5 years of the survey and that are confirmed as quasars via visual inspection of the spectra, have lumino…
