On the origin of cold dark matter halo density profiles
dark matter large-scale structure of the universe
2014/12/24
N-body simulations predict that cold dark matter (CDM) halo-assembly occurs in two phases: (i) a fast-accretion phase with a rapidly deepening potential well; and (ii) a slow-accretion phase character...
The role of the initial surface density profiles of the disc on giant planet formation: comparing with observations
the initial surface density profiles the disc on giant planet formation
2011/1/10
In order to explain the main characteristics of the observed population of extrasolar planets and the giant planets in the Solar System, we need to get a clear understanding of which are the initial c...

Galaxy clustering projected density profiles photometric surveys
2010/11/12
We develop a new method which measures the projected density distribution wp(rp)n of photometric galaxies surrounding a set of spectroscopically-identified galaxies, and simultaneously the projected c...

DARK MATTER HALOES：AN ADDITIONAL CRITERION FOR THE CHOICE OF FITTING DENSITY PROFILES
cosmology dark matter
2009/3/5
Simulated dark matter haloes are tted by self-similar, universal
density pro les, where the scaled parameters depend only on a scaled (truncation)
radius, = R=r0, which, in turn, is supposed to b...
