Quantum Origin of the Primordial Fluctuation Spectrum and its Statistics
Quantum Origin Primordial Fluctuation Spectrum Statistics
2011/10/9
The account of the origin of cosmic structure, as provided by the standard inflationary paradigm, is not fully satisfactory, as has been argued in Perez et al 2006. The central point of that work is t...
Origin and Dynamical Evolution of Neptune Trojans - II: Long Term Evolution
Kuiper Belt celestial mechanics minor planets asteroids – Solar system
2010/11/10
Following our earlier work studying the formation of the Neptunian Trojan population during the
planet’s migration, we present results examining the eventual fate of the Trojan clouds produced in tha...
The Origin of [OII] Emission in Recently Quenched AGN Hosts
galaxies active — galaxies clusters general — galaxies evolution X-rays galaxies
2010/11/11
We have employed emission-line diagnostics derived from DEIMOS and NIRSPEC spectroscopy to
determine the origin of the [OII] emission line observed in six AGN hosts at z 0.9. These galaxies are a s...
Origin of Molecular Outflow Determined from Thermal Dust Polarization
formation ISM jets and outflows magnetic fields polarization methods numerical
2010/11/9
The observational expectation of polarization measurements of thermal dust ra-diation is investigated to find information on molecular outflows based on magne-tohydrodynamical (MHD) and radiation tran...
On the origin of the red excess in very young super star clusters: the case of SBS 0335-052E
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/7
The spectral energy distribution analysis of very young unresolved star clusters challenges our understanding of the cluster formation process. Studies of resolved massive clusters in the Milky Way an...
Testing a prediction of the merger origin of early-type galaxies: a correlation between stellar populations and asymmetry
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
One of the key predictions of the merger hypothesis for the origin of early-type (elliptical and lenticular) galaxies is that tidally-induced asymmetric structure should correlate with signatures of a...
