Excitation of H in photodissociation regions as seen by Spitzer
Emilie Habart, Alain Abergel, Francois Boulanger +5
We present spectroscopic observations obtained with the infrared Spitzer Space Telescope, which provide insight into the H physics and gas energetics in photodissociation Regio…
Modeling the Magnetic Field in the Galactic Disk using New Rotation Measure Observations from the Very Large Array
Cameron Van Eck, Jo-Anne Brown, Jeroen Stil +8
We have determined 194 Faraday rotation measures (RMs) of polarized extragalactic radio sources using new, multi-channel polarization observations at frequencies around 1.4 GHz fro…
Numerical Parameter Survey of Nonradiative Black Hole Accretion -- Flow Structure and Variability of the Rotation Measure
Bijia Pang, Ue-Li Pen, Christopher D. Matzner +2
We conduct a survey of numerical simulations to probe the structure and appearance of non-radiative black hole accretion flows like the supermassive black hole at the Galactic cent…
Deconvolution of Images from BLAST 2005: Insight into the K3-50 and IC 5146 Star-Forming Regions
Arabindo Roy, Peter A. R. Ade, James J. Bock +26
We present an implementation of the iterative flux-conserving Lucy-Richardson (L-R) deconvolution method of image restoration for maps produced by the Balloon-borne Large Aperture…
Dust in the diffuse emission of the galactic plane - The Herschel/Spitzer SED fitting
M. Compiegne, N. Flagey, A. Noriega-Crespo +4
The first Herschel Hi-Gal images of the galactic plane unveil the far-infrared diffuse emission of the interstellar medium with an unprecedented angular resolution and sensitivity.…
The global dust SED: Tracing the nature and evolution of dust with DustEM
M. Compiegne, L. Verstraete, A. Jones +6
The Planck and Herschel missions are currently measuring the farIR-mm emission of dust, which combined with existing IR data, will for the first time provide the full SED of the ga…
