A Molecular Line Scan in the Hubble Deep Field North: Constraints on the CO Luminosity Function and the Cosmic H2 Density
F. Walter, R. Decarli, M. Sargent +19
We present direct constraints on the CO luminosity function at high redshift and the resulting cosmic evolution of the molecular gas density, (z), based on a blind mole…
A molecular line scan in the Hubble Deep Field North
R. Decarli, F. Walter, C. Carilli +20
We present a molecular line scan in the Hubble Deep Field North (HDF-N) that covers the entire 3mm window (79-115 GHz) using the IRAM Plateau de Bure Interferometer. Our CO redshif…
HOPS 136: An Edge-On Orion Protostar Near the End of Envelope Infall
William J. Fischer, S. Thomas Megeath, John J. Tobin +10
Edge-on protostars are valuable for understanding the disk and envelope properties of embedded young stellar objects, since the disk, envelope, and envelope cavities are all distin…
Formation and collimation of relativistic MHD jets - simulations and radio maps
Christian Fendt, Oliver Porth, Somayeh Sheikhnezami
We present results of magnetohydrodynamic (MHD) simulations of jet formation and propagation, discussing a variety of astrophysical setups. In the first approach we consider simula…
Formation of silicon oxide grains at low temperature
S. A. Krasnokutski, G. Rouille, C. Jager +3
The formation of grains in the interstellar medium, i.e., at low temperature, has been proposed as a possibility to solve the lifetime problem of cosmic dust. This process lacks a…
Brown Dwarf Photospheres are Patchy: A Hubble Space Telescope Near-infrared Spectroscopic Survey Finds Frequent Low-level Variability
Esther Buenzli, Daniel Apai, Jacqueline Radigan +2
Condensate clouds strongly impact the spectra of brown dwarfs and exoplanets. Recent discoveries of variable L/T transition dwarfs argued for patchy clouds in at least some ultraco…
Discovery of three z>6.5 quasars in the VISTA Kilo-degree Infrared Galaxy (VIKING) survey
B. P. Venemans, J. R. Findlay, W. J. Sutherland +6
Studying quasars at the highest redshifts can constrain models of galaxy and black hole formation, and it also probes the intergalactic medium in the early universe. Optical survey…
Detection of a Noble Gas Molecular Ion, {36}ArH^+, in the Crab Nebula
M. J. Barlow, B. M. Swinyard, P. J. Owen +9
Noble gas molecules have not hitherto been detected in space. From spectra obtained with the Herschel Space Observatory, we report the detection of emission in the 617.5 GHz and 12…
Virgo Cluster and field dwarf ellipticals in 3D - II. Internal dynamics points to tidal harassment?
Agnieszka Ryś, Glenn van de Ven, Jesús Falcón-Barroso
We present the dynamical analysis of a sample of 12 dwarf elliptical (dE) galaxies for which we have obtained SAURON large-scale two-dimensional spectroscopic data. We construct Je…
The dusty torus in the Circinus galaxy: a dense disk and the torus funnel
K. R. W. Tristram, L. Burtscher, W. Jaffe +5
(Abridged) With infrared interferometry it is possible to resolve the nuclear dust distributions that are commonly associated with the dusty torus in active galactic nuclei (AGN).…
Kepler-91b: a planet at the end of its life. Planet and giant host star properties via light-curve variations
J. Lillo-Box, D. Barrado, A. Moya +8
The evolution of planetary systems is intimately linked to the evolution of their host star. Our understanding of the whole planetary evolution process is based on the large planet…
A Herschel view of IC 1396 A: Unveiling the different sequences of star formation
Aurora Sicilia-Aguilar, Veronica Roccatagliata, Konstantin Getman +5
The IC1396A globule in the young cluster Tr37, hosting many young stars and protostars, is assumed to be a site of triggered star formation. We mapped IC1396A with Herschel/PACS at…
Gas-to-Dust mass ratios in local galaxies over a 2 dex metallicity range
A. Rémy-Ruyer, S. C. Madden, F. Galliano +17
This paper analyses the behaviour of the gas-to-dust mass ratio (G/D) of local Universe galaxies over a large metallicity range. We combine three samples: the Dwarf Galaxy Survey,…
3D Galactic dust extinction mapping with multi-band photometry
R. J. Hanson, C. A. L. Bailer-Jones
We present a method to simultaneously infer the interstellar extinction parameters and , stellar effective temperature , and distance modulus in a Bayes…
An Atlas of Galaxy Spectral Energy Distributions from the Ultraviolet to the Mid-Infrared
Michael J. I. Brown, John Moustakas, J. -D. T. Smith +6
We present an atlas of 129 spectral energy distributions for nearby galaxies, with wavelength coverage spanning from the UV to the mid-infrared. Our atlas spans a broad range of ga…
AGN X-ray variability in the XMM-COSMOS survey
G. Lanzuisi, G. Ponti, M. Salvato +18
We took advantage of the observations carried out by XMM in the COSMOS field during 3.5 years, to study the long term variability of a large sample of AGN (638 sources), in a wide…
Stellar Diameters and Temperatures V. Eleven Newly Characterized Exoplanet Host Stars
Kaspar von Braun, Tabetha S. Boyajian, Gerard T. van Belle +17
We use near-infrared interferometric data coupled with trigonometric parallax values and spectral energy distribution fitting to directly determine stellar radii, effective tempera…
