Measurements of cosmic-ray secondary nuclei at high energies with the first flight of the CREAM balloon-borne experiment
H. S. Ahn, P. S. Allison, M. G. Bagliesi +34
We present new measurements of heavy cosmic-ray nuclei at high energies per- formed during the first flight of the balloon-borne cosmic-ray experiment CREAM (Cosmic-Ray Energetics…
SCUBA Mapping of Outer Galaxy Protostellar Candidates
B. Mookerjea, G. Sandell, J. Stutzki +1
We aim to study dust properties of massive star forming regions in the outer Galaxy, in a direction opposite to the Galactic center. We present observations of six outer Galaxy poi…
The Space Infrared Interferometric Telescope (SPIRIT): High-resolution imaging and spectroscopy in the far-infrared
David Leisawitz, Charles Baker, Amy Barger +53
We report results of a recently-completed pre-Formulation Phase study of SPIRIT, a candidate NASA Origins Probe mission. SPIRIT is a spatial and spectral interferometer with an ope…
Absolute diffuse calibration of IRAC through mid-infrared and radio study of HII regions
Martin Cohen, Anne J. Green, Marilyn R. Meade +9
We investigate the diffuse absolute calibration of the InfraRed Array Camera on the Spitzer Space Telescope at 8.0microns using a sample of 43 HII regions with a wide range of morp…
[CI] 492 GHz mapping toward Cas A
B. Mookerjea, N. G. Kantharia, D. A. Roshi +2
We have mapped the [C I] emission at 492 GHz toward the supernova remnant Cas A. We detect [C I] emission from the periphery of the diffuse Photon Dominated Region (PDR) covering t…
Study of Photon Dominated Regions in Cepheus B
B. Mookerjea, C. Kramer, M. Roellig +1
Aim: The aim of the paper is to understand the emission from the photon dominated regions in Cepheus B, estimate the column densities of neutral carbon in bulk of the gas in Cepheu…
Outflows in Infrared-Luminous Starbursts at z < 0.5. II. Analysis and Discussion
David S. Rupke, Sylvain Veilleux, D. B. Sanders
We have performed an absorption-line survey of outflowing gas in 78 starburst-dominated, infrared-luminous galaxies. This is the largest study of superwinds at z < 3. Superwinds ar…
Outflows in Infrared-Luminous Starbursts at z < 0.5. I. Sample, NaI D Spectra, and Profile Fitting
David S. Rupke, Sylvain Veilleux, D. B. Sanders
We have conducted a spectroscopic survey of 78 starbursting infrared-luminous galaxies at redshifts up to z = 0.5. We use moderate-resolution spectroscopy of the NaI D interstellar…
Photoionization Modeling and the K Lines of Iron
T. R. Kallman, P. Palmeri, M. A. Bautista +2
We calculate the efficiency of iron K line emission and iron K absorption in photoionized models using a new set of atomic data. These data are more comprehensive than those previo…
XMM-Newton observation of Kepler's supernova remnant
G. Cassam-Chenai, A. Decourchelle, J. Ballet +3
We present the first results coming from the observation of Kepler's supernova remnant obtained with the EPIC instruments on board the XMM-Newton satellite. We focus on the images…
X-Ray Constraints on the Warm_hot Intergalactic Medium
K. D. Kuntz, S. L. Snowden, R. F. Mushotzky
Three observational constraints can be placed on a warm-hot intergalactic medium (WHIM) using \rosat PSPC pointed and survey data, the emission strength, the energy spectrum, and t…
A radiation-driven disk wind model for massive young stellar objects
Janet E. Drew, Daniel Proga, James M. Stone
A radiation-driven disk wind model is proposed that offers great promise of explaining the extreme mass loss signatures of massive young stellar objects (the BN-type objects and mo…
Lithium and binarity in M67
D. Barrado y Navascues, J. R. Stauffer, S. Balachandran
A study of the lithium abundances in binaries of the old open cluster M67 is presented. Abundances were estimated using curves of growth and equivalent widths of the LiI6707.8 Å do…
