Radio-to-Far-Infrared Spectral Energy Distribution and Photometric Redshifts for Dusty Starburst Galaxies
galaxies photometric
2014/12/26
As a logical next step in improving the radio-to-submillimeter spectral index as a redshift indicator, we have investigated a technique of using the entire radio-to-far-infrared spectral energy distri...
Black hole X-ray binaries LMC X–1 and X–3: observations confront spectral models
LMC X–1 LMC X–3
2014/12/24
We present a comprehensive spectral analysis of black hole X-ray binaries, LMC X–1 and X–3, based on BeppoSAX observations. We test both the multicolour disc plus power-law (MCD+PL) model and a newly ...
The Bolocam 1.1 mm Lockman Hole Galaxy Survey: SHARC II 350 μm Photometry and Implications for Spectral Models, Dust Temperatures, and Redshift Estimation
starburst submillimeter
2014/12/23
We present 350 μm photometry of all 17 galaxy candidates in the Lockman Hole detected in a 1.1 mm Bolocam survey. Several of the galaxies were previously detected at 850 μm, at 1.2 mm, in the infrared...
Spitzer spectral line mapping of supernova remnants. I. Basic data and principal component analysis
Molecules Abundances
2014/12/23
We report the results of spectroscopic mapping observations carried out toward small (1' × 1') regions within the supernova remnants W44, W28, IC 443, and 3C 391 using the Infrared Spectrograph (IRS) ...
Large-scale structure of the molecular gas in Taurus revealed by high linear dynamic range spectral line mapping
molecules structure
2014/12/23
We report the results of a 100 deg2 survey of the Taurus molecular cloud region in 12CO and 13CO J = 1→ 0. The image of the cloud in each velocity channel includes 3 × 106 Nyquist-sampled pixels on a ...
Complex Radio Spectral Energy Distributions in Luminous and Ultraluminous Infrared Galaxies
Complex Radio Spectral Energy Distributions Luminous Ultraluminous Infrared
2011/10/12
We use the Expanded Very Large Array to image radio continuum emission from local luminous and ultraluminous infrared galaxies (LIRGs and ULIRGs) in 1 GHz windows centered at 4.7, 7.2, 29, and 36 GHz....
3-D deconvolution of hyper-spectral astronomical data
Supernova – inverse problem – deconvolution – hyperspectral imaging
2011/10/12
In this paper we present a general forward fitting method for multichannel image restoration based on regularized chi2. We introduce separable regularizations that account for the dynamic of the model...
GRB 070125 and the environments of spectral-line poor afterglow absorbers
gamma-ray burst: individual: GRB070125
2011/10/11
GRB 070125 is among the most energetic bursts detected and the most extensively observed so far. Nevertheless, unresolved issues are still open in the literature on the physics of the afterglow and on...
Multiwavelength campaign on Mrk 509. I. Variability and spectral energy distribution
Galaxies: active – quasars: absorption lines – X-rays: general
2011/9/27
(Abridged) Active galactic nuclei show a wealth of interesting physical processes, some of which are poorly understood. We want to address a number of open questions, including the location and physic...
