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 ...
A spectral code for non-equilibrium plasma and its applications
Spectrum Nonequilibrium plasma The program code
2014/12/9
The spectral code for non-equilibrium plasma has been developed based on the updated atomic database. The first application is for winds from super stellar clusters for which a self-consistent physica...
A Frequency Selective Bolometer Camera for Measuring Millimeter Spectral Energy Distributions
Bolometer cameras Frequency selective surfaces Millimeter Transition-edge sensors Energy distributions
2014/12/9
Bolometers are the most sensitive detectors for measuring millimeter and submillimeter wavelength astrophysical signals. Cameras comprised of arrays of bolometers have already made significant contrib...

2014/12/9
Comprehensive and robust analysis of galaxies found throughout cosmic time provides the means to probe the underlying characteristics of our Universe. Coupling observations and theory, spectral energy...
The Unusual Temporal and Spectral Evolution of the Type IIn Supernova 2011ht
Unusual Temporal Spectral Evolution Type IIn Supernova
2012/2/23
We present very early UV to optical photometric and spectroscopic observations of the peculiar Type IIn supernova (SN) 2011ht in UGC 5460. The UV observations of the rise to peak are only the second e...
Joint spectral-timing modelling of the hard lags in GX 339-4: constraints on reflection models
Joint spectral-timing modelling the hard lags GX 339-4 constraints reflection models
2012/2/23
The X-ray variations of hard state black hole X-ray binaries above 2 keV show 'hard lags', in that the variations at harder energies follow variations at softer energies, with a time-lag \tau dependin...
Sc III Spectral Properties of Astrophysical Interest

2011/10/18
Transition properties such as oscillator strengths, transition rates, branching ratios and lifetimes of many low-lying states in the doubly ionized scandium (Sc III) are reported. A relativistic metho...

high-spectral resolution interferometry stars disks
2011/10/17
High spectral-resolution Br-gamma VLTI/AMBER observations of classical Be stars reveal complex visibility, phase, and closure phase profiles, which were not seen in previous lower-resolution data. The...
