A Herschel Search for Cold Dust in Brown Dwarf Disks: First Results
Pascucci, Ilaria; Henning, Thomas; Ménard, François +7 more
We report initial results from a Herschel program to search for far-infrared emission from cold dust around a statistically significant sample of young brown dwarfs. The first three objects in our survey are all detected at 70 µm, and we report the first detection of a brown dwarf at 160 µm. The flux densities are consistent with the p…
A journey from the outskirts to the cores of groups. I. Color- and mass-segregation in 20K-zCOSMOS groups
Finoguenov, A.; Kneib, J. -P.; Cimatti, A. +49 more
Context. Studying theevolution of galaxies located within groups may have important implications for our understanding of the global evolution of the galaxy population as a whole. The fraction of galaxies bound in groups at z ~ 0 is as high as 60% and therefore any mechanism (among the many suggested) that could quench star formation when a galaxy…
Probing the nuclear and circumnuclear activity of NGC 1365 in the infrared
Esquej, P.; Hatziminaoglou, E.; Acosta-Pulido, J. A. +12 more
We present new far-infrared (70-500 µm) Herschel Photodetector Array Camera and Spectrometer (PACS) and Spectral and Photometric Imaging Receiver (SPIRE) imaging observations as well as new mid-IR Gemini/Thermal-Region Camera Spectrograph imaging (8.7 and 18.3 µm) and spectroscopy of the inner Lindblad resonance (ILR) region (R < 2.…
An MHD simulation model of time-dependent co-rotating solar wind
Hayashi, K.
We present a treatment of observation-based time-dependent boundary conditions for the inner boundary sphere in the time-dependent three-dimensional MHD simulations of the global solar wind. With this boundary treatment, we obtain super-Alfvenic MHD solutions of time-dependent co-rotating solar wind structures. The boundary variables on the inner …
FMOS near-IR spectroscopy of Herschel-selected galaxies: star formation rates, metallicity and dust attenuation at z ∼ 1
Clements, D. L.; Dunlop, J. S.; Buat, V. +36 more
We investigate the properties (e.g. star formation rate, dust attenuation, stellar mass and metallicity) of a sample of infrared (IR) luminous galaxies at z ∼ 1 via near-IR spectroscopy with Subaru-FMOS. Our sample consists of Herschel SPIRE and Spitzer MIPS selected sources in the COSMOS field with photometric redshifts in the range of 0.7 < z…
Detecting the Warm-Hot Intergalactic Medium through X-Ray Absorption Lines
Shull, J. Michael; Wang, Q. Daniel; Yao, Yangsen +1 more
The warm-hot intergalactic medium (WHIM) at temperatures 105-107 K is believed to contain 30%-50% of the baryons in the local universe. However, all current X-ray detections of the WHIM at redshifts z > 0 are of low statistical significance (lsim 3σ) and/or controversial. In this work, we aim to establish the detection lim…
Far-ultraviolet Continuum Emission: Applying This Diagnostic to the Chromospheres of Solar-mass Stars
France, Kevin; Linsky, Jeffrey L.; Ayres, Tom +2 more
The far-ultraviolet (FUV) continuum flux is recognized as a very sensitive diagnostic of the temperature structure of the Sun's lower chromosphere. Until now analysis of the available stellar FUV data has shown that solar-type stars must also have chromospheres, but quantitative analyses of stellar FUV continua require far higher quality spectra a…
Investigation of Intermittency in Magnetohydrodynamics and Solar Wind Turbulence: Scale-dependent Kurtosis
Oughton, Sean; Matthaeus, William H.; Wan, Minping +1 more
The behavior of scale-dependent (or filtered) kurtosis is studied in the solar wind using magnetic field measurements from the ACE and Cluster spacecraft at 1 AU. It is also analyzed numerically with high-resolution magnetohydrodynamic spectral simulations. In each case the filtered kurtosis increases with wavenumber, implying the presence of cohe…
SHARP - I. A high-resolution multiband view of the infrared Einstein ring of JVAS B1938+666
Vegetti, S.; McKean, J. P.; Auger, M. W. +3 more
We present new mass models for the gravitational lens system B1938+666, using multiwavelength data acquired from Keck adaptive optics (AO) and Hubble Space Telescope (HST) observations. These models are the first results from the Strong lensing at High Angular Resolution Program (SHARP), a project designed to study known quadruple image and Einste…
