Dust grain growth in the interstellar medium of galaxies at redshifts 4
Dust grain growth interstellar medium galaxies redshifts
2011/10/21
To discriminate between different dust formation processes is a key issue in order to understand its properties. We analysed six submillimeter galaxies at redshifts 4
The Absence of Cold Dust and the Mineralogy and Origin of the Warm Dust Encircling BD +20 307
Cold Dust the Mineralogy the Warm Dust Encircling
2011/1/13
Spitzer Space Telescope photometry and spectroscopy of BD +20 307 show that all of the dust around this remarkable Gyr-old spectroscopic binary arises within 1 AU. No additional cold dust is needed to...
On the redshift-evolution of the Lyman-alpha escape fraction and the dust content of galaxies
the redshift-evolution the Lyman-alpha escape fraction
2011/1/10
The Ly-alpha emission line has been proven a powerful tool by which to study evolving galaxies at the highest redshifts. However, in order to use Lya as a physical probe of galaxies, it becomes vital ...
Galactic cirrus emission at far-infrared wavelengths affects many extragalactic observations. Separating this emission from that associated with extragalactic objects is both important and difficult. ...
Metallicities and dust content of proximate damped Lyman alpha systems in the Sloan Digital Sky Survey
Metallicities dust content proximate damped Lyman alpha systems
2011/1/11
Composite spectra of 85 proximate absorbers (log N(HI)>20 and velocity difference between the absorption and emission redshift, dv<10,000 km/s) in the SDSS are used to investigate the trends of metal ...
Evaluating and Improving Semi-analytic modeling of Dust in Galaxies based on Radiative Transfer Calculations II: Dust Emission in the Infrared
galaxies evolution - galaxies dust
2010/11/10
Interstellar dust grains are responsible for modifying the spectral energy distribution
(SED) of galaxies, both absorbing starlight at UV and optical wavelengths and con-verting this energy into ther...
Supernova dust for the extinction law in a young infrared galaxy at z = 1
dust extinction — galaxies evolution — galaxies ISM — galaxies starburst — infrared galaxies — supernovae general
2010/11/10
We apply the supernova(SN) extinction curves to reproduce the observed properties of SST J1604+4304 which is a young infrared (IR) galaxy at z ∼ 1. The SN extinction curves used in this work wer...
The thesis deals with the first stage of planet formation, namely dust coagulation from
micron to millimeter sizes in circumstellar disks. For the first time, we collect and compile
the recent labor...
The global dust SED: Tracing the nature and evolution of dust with DustEM
Galaxy Astrophysics (astro-ph.GA)
2011/1/4
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 galactic ISM dust emis...
Evolution of Infrared Luminosity functions of Galaxies in the AKARI NEP-Deep field: Revealing the cosmic star formation history hidden by dust
galaxies evolution galaxies interactions galaxies:starburst galaxies peculiar galaxies formation
2010/3/8
Dust-obscured star-formation becomes much more important with increasing intensity, and increasing redshift. We aim to reveal cosmic star-formation history obscured by dust using deep infrared observa...
Near-IR dust and line emission from the central region of Mrk1066: Constraints from Gemini NIFS
Near-IR dust Gemini NIFS line emission
2010/3/8
We present integral field spectroscopy of the inner 350 pc of the Mrk1066 obtained with Gemini NIFS at a spatial resolution of 35 pc. This high spatial resolution allowed us to observe, for the first ...
