The HIFI spectral survey of AFGL 2591 (CHESS). III. Chemical structure of the protostellar envelope
Maja Kazmierczak-Barthel, Dimitri Semenov, Floris van der Tak +2
We aim to understand the rich chemical composition of AFGL 2591, a prototypical isolated high-mass star-forming region. Based on HIFI and JCMT data, the molecular abundances of spe…
Observations of water with Herschel/HIFI toward the high-mass protostar AFGL 2591
Y. Choi, F. F. S. van der Tak, E. F. van Dishoeck +2
Water is a sensitive tracer of physical conditions in star-forming regions because of its large abundance variations between hot and cold regions. We use spectrally resolved observ…
Herschel Survey of Galactic OH+, H2O+, and H3O+: Probing the Molecular Hydrogen Fraction and Cosmic-Ray Ionization Rate
Nick Indriolo, D. A. Neufeld, M. Gerin +19
In diffuse interstellar clouds the chemistry that leads to the formation of the oxygen bearing ions OH+, H2O+, and H3O+ begins with the ionization of atomic hydrogen by cosmic rays…
The evolution of the cold interstellar medium in galaxies following a starburst
K. Rowlands, V. Wild, N. Nesvadba +4
We present the evolution of dust and molecular gas properties in a sample of 11 starburst to post-starburst (PSB) galaxies selected to span an age sequence from ongoing…
Anatomy of the AGN in NGC 5548: II. The Spatial, Temporal and Physical Nature of the Outflow from HST/COS Observations
N. Arav, C. Chamberlain, G. A. Kriss +30
(Abridged) Our deep multiwavelength campaign on NGC 5548 revealed an unusually strong X-ray obscuration. The resulting dramatic decrease in incident ionizing flux allowed us to con…
CARMA Large Area Star Formation Survey: Structure and Kinematics of Dense Gas in Serpens Main
Katherine I. Lee, Manuel Fernandez-Lopez, Shaye Storm +21
We present observations of N2H+(1-0), HCO+(1-0), and HCN(1-0) toward the Serpens Main molecular cloud from the CARMA Large Area Star Formation Survey (CLASSy). We mapped 150 square…
LOFAR low-band antenna observations of the 3C295 and Bootes fields: source counts and ultra-steep spectrum sources
R. J. van Weeren, W. L. Williams, C. Tasse +98
We present LOFAR Low Band observations of the Bootes and 3C295 fields. Our images made at 34, 46, and 62 MHz reach noise levels of 12, 8, and 5 mJy beam, making them the dee…
Spatially Resolved Magnetic Field Structure in the Disk of a T Tauri Star
Ian W. Stephens, Leslie W. Looney, Woojin Kwon +6
Magnetic fields in accretion disks play a dominant role during the star formation process but have hitherto been observationally poorly constrained. Field strengths have been infer…
A non-equilibrium ortho-to-para ratio of water in the Orion PDR
Y. Choi, F. F. S. van der Tak, E. A. Bergin +1
The ortho-to-para ratio (OPR) of HO is thought to be sensitive to the temperature of water formation. The OPR of HO is thus useful to study the formation mechanism of water…
CARMA Large Area Star Formation Survey: Project Overview with Analysis of Dense Gas Structure and Kinematics in Barnard 1
S. Storm, L. G. Mundy, M. Fernández-López +22
We present details of the CARMA Large Area Star Formation Survey (CLASSy), while focusing on observations of Barnard 1. CLASSy is a CARMA Key Project that spectrally imaged N2H+, H…
Herschel HIFI observations of O toward Orion: special conditions for shock enhanced emission
Jo-Hsin Chen, Paul F. Goldsmith, Serena Viti +18
We report observations of molecular oxygen (O) rotational transitions at 487 GHz, 774 GHz, and 1121 GHz toward Orion Peak A. The O2 lines at 487 GHz and 774 GHz are detected at…
CARMA Large Area Star Formation Survey: Observational Analysis of Filaments in the Serpens South Molecular Cloud
M. Fernández-López, H. G. Arce, L. Looney +15
We present the N2H+(J=1-0) map of the Serpens South molecular cloud obtained as part of the CARMA Large Area Star Formation Survey (CLASSy). The observations cover 250 square arcmi…
Initial LOFAR observations of Epoch of Reionization windows: II. Diffuse polarized emission in the ELAIS-N1 field
V. Jelic, A. G. de Bruyn, M. Mevius +106
This study aims to characterise the polarized foreground emission in the ELAIS-N1 field and to address its possible implications for the extraction of the cosmological 21-cm signal…
A necklace of dense cores in the high-mass star forming region G35.20-0.74N: ALMA observations
Á. Sánchez-Monge, M. T. Beltrán, R. Cesaroni +13
The present study aims at characterizing the massive star forming region G35.20N, which is found associated with at least one massive outflow and contains multiple dense cores, one…
The IRAM M33 CO(2-1) Survey - A complete census of the molecular gas out to 7 kpc
C. Druard, J. Braine, K. F. Schuster +11
In order to study the ISM and the interplay between the atomic and molecular components in a low-metallicity environment, we present a complete high angular and spectral resolution…
