Detection of infalling hydrogen in transfer between the interacting galaxies NGC 5426 and NGC 5427

Joan Font, John E. Beckman, Margarita Rosado +8

Using velocity tagging we have detected hydrogen from NGC 5426 falling onto its interacting partner NGC 5427. Our observations, with the GHaFaS Fabry-Perot spectrometer, produced m…

The Herschel M33 extended survey (HerM33es): PACS spectroscopy of the star forming region BCLMP 302

B. Mookerjea, C. Kramer, C. Buchbender +19

Context: The emission line of [CII] at 158 micron is one of the strongest cooling lines of the interstellar medium (ISM) in galaxies. Aims: Disentangling the relative contributions…

Planck Early Results: The Galactic Cold Core Population revealed by the first all-sky survey

Planck Collaboration, P. A. R. Ade, N. Aghanim +202

We present the statistical properties of the first version of the Cold Core Catalogue of Planck Objects (C3PO), in terms of their spatial distribution, temperature, distance, mass,…

Planck Early Results: The submillimetre properties of a sample of Galactic cold clumps

Planck Collaboration, P. A. R. Ade, N. Aghanim +201

(abridged) We perform a detailed investigation of sources from the Cold Cores Catalogue of Planck Objects (C3PO). Our goal is to probe the reliability of the detections, validate t…

Planck Early Results: All sky temperature and dust optical depth from Planck and IRAS: Constraints on the "dark gas" in our galaxy

Planck Collaboration, P. A. R. Ade, N. Aghanim +204

We construct an all-sky map of the apparent temperature and optical depth of thermal dust emission using the Planck-HFI and IRAS data. The optical depth maps are correlated to trac…

Planck early results. XV. Spectral energy distributions and radio continuum spectra of northern extragalactic radio sources

Planck Collaboration, J. Aatrokoski, P. A. R. Ade +246

Spectral energy distributions (SEDs) and radio continuum spectra are presented for a northern sample of 104 extragalactic radio sources, based on the Planck Early Release Compact S…

Planck Early Results: Thermal dust in Nearby Molecular Clouds

Planck Collaboration, A. Abergel, P. A. R. Ade +197

Planck allows unbiased mapping of Galactic sub-millimetre and millimetre emission from the most diffuse regions to the densest parts of molecular clouds. We present an early analys…

Planck Early Results XXIV: Dust in the diffuse interstellar medium and the Galactic halo

Planck Collaboration, A. Abergel, P. A. R. Ade +205

This paper presents the first results of comparison of Planck along with IRAS data with Green Bank Telescope 21-cm observations in 14 fields covering more than 800 square degrees a…

Planck early results. XXI. Properties of the interstellar medium in the Galactic plane

Planck Collaboration, A. Abergel, P. A. R. Ade +199

(abridged) Planck has observed the entire sky from 30 GHz to 857GHz. The observed foreground emission contains contributions from different phases of the interstellar medium (ISM).…

Planck early results. XX. New light on anomalous microwave emission from spinning dust grains

Planck Collaboration, P. A. R. Ade, N. Aghanim +213

Anomalous microwave emission (AME) has been observed by numerous experiments in the frequency range ~10-60 GHz. Using Planck maps and multi-frequency ancillary data, we have constr…
