Star Formation Rates and Stellar Masses of H-alpha Selected Star-Forming Galaxies at z=0.84: A Quantification of the Downsizing
Star Formation Rates Stellar Masses H-alpha Selected Star-Forming Galaxies Quantification Downsizing
2011/10/13
In this work we analyze the physical properties of a sample of 153 star forming galaxies at z~0.84, selected by their H-alpha flux with a NB filter. B-band luminosities of the objects are higher than ...
Reconciling a significant hierarchical assembly of massive early-type galaxies at z<~1 with mass downsizing
massive early-type galaxies Cosmology and Extragalactic Astrophysics
2011/1/11
Hierarchical models predict that massive early-type galaxies (mETGs) are the latest systems to be in place into the cosmic scenario (at z<~0.5), conflicting with the observational phenomenon of galaxy...
Rotation of the Solar System planets and the origin of the Moon in the context of the tidal downsizing hypothesis
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/27
It has been proposed recently that the first step in the formation of both rocky and gas giant planets is dust sedimentation into a solid core inside a gas clump (giant planet embryo). The clumps are ...
