Star formation trends in high-redshift galaxy surveys: the elephant or the tail?
high-redshift galaxy elephan tail
2010/11/15
Star formation rate and accummulated stellar mass are two fundamental physical quantities that describe the evolutionary state of a forming galaxy. Two recent at-tempts to determine the relationship b...
The M_BH-M_star relation of obscured AGNs at high redshift
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
2010/12/24
We report the detection of broad Halpha emission in three X-ray selected obscured AGNs at z=1-2. By exploiting the Halpha width and the intrinsic X-ray luminosity, we estimate their black hole masses,...
Morphology and Size Differences between Local & High Redshift Luminous Infrared Galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We show that the star-forming regions in high-redshift luminous and ultraluminous infrared galaxies (LIRGs and ULIRGs) and submillimeter galaxies (SMGs) have similar physical scales to those in local ...
Numerical simulations of Optical Turbulence at low and high horizontal resolution in Antarctica with a mesoscale meteorological model
horizontal resolution Optical Turbulence
2010/3/9
It has already been demonstrated that a mesoscale meteorological model such as Meso-NH is highly reliable in reproducing 3D maps of optical turbulence. Preliminary measurements above the Antarctic Pla...
