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...
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...
Characterizing Distant Galaxies: Spectral Energy Distribution Analysis of X-ray Selected Star Forming 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....
The New Generation Atlas of Quasar Spectral Energy Distributions from Radio to X-rays
Generation Atlas Spectral Energy Distributions Radio
2011/9/30
We have produced the next generation of quasar spectral energy distributions (SEDs), essentially updating the work of Elvis et al. (1994) by using high-quality data obtained with several space and gro...
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...
Spectral Energy Distribution variation in BL Lacs and FSRQs
Radiation mechanisms: non-thermal – Galaxies: active – BL Lacertae objects: general
2011/9/27
We present the results of our study of spectral energy distributions (SEDs) of a sample of ten low- to intermediate-synchrotron-peaked blazars. We investigate some of the physical parameters most like...
Modelling the spectral energy distribution of galaxies. V. The dust and PAH emission SEDs of disk galaxies

2010/11/9
The correlations between the rest frame peak of the F spectrum of GRBs (Epeak) and their
isotropic energy (Eiso) or luminosity (Liso) could have several implications for the understanding of the GR...
Spectral Energy Distribution of z>1 Type Ia Supernova Hosts in GOODS: Constraints on Evolutionary Delay and the Initial Mass Function
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/6
We identify a sample of 22 host galaxies of Type Ia Supernovae (SNe Ia) at redshifts 0.95scovered in the Hubble Space Telescope (HST) observations of the Great Observatories Origins Deep Surv...
Star Formation in Collision Debris: Insights from the modeling of their Spectral Energy Distribution
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
2010/12/28
During galaxy-galaxy interactions, massive gas clouds can be injected into the intergalactic medium which in turn become gravitationally bound, collapse and form stars, star clusters or even dwarf gal...
Modeling of the spectral energy distribution of the cataclysmic variable TT Ari and evaluation of the system parameters
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
The spectral energy distribution (SED) of the TT Ari system, which is well known from published IUE and optical photometric observations, was modeled by a steady-state accretion \alpha-disc around a w...
