Star formation trends in high-redshift galaxy surveys: the elephant or the 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 ...
