Pairwise Velocities of Dark Matter Halos: a Test for the Lambda Cold Dark Matter Model using the Bullet Cluster
method : N-body simulations — galaxies : evolution — galaxies : for-mation — galaxies: clusters — cosmology : theory — cosmology : dark matter
2011/10/13
The existence of a bullet cluster (such as 1E0657-56) poses a challenge to the concordance Lambda cold dark matter model. Here we investigate the velocity distribution of dark matter halo pairs in lar...
Fourth-order gravity as the inflationary model revisited
Fourth-order gravity inflationary model
2010/3/19
We revisit the simplest (fourth-order or quadratically generated) modified gravity model in four space-time dimensions. It is equivalent to the certain quintessence model via a Legendre-Weyl transform...

Evolution of the Distribution of Neutron Exposures in the Galaxy Disc：An Analytical Model
Nucleosynthesis neutron exposures abundances stars:AGB stars:low-mass stars galaxy:evolution

In this work, based on the analytical model with delayed production
approximation developed by Pagel & Tautvaiˇsien˙e (1995) for the
Galaxy, the analytic solutions of the distribution of neutron e...
Report on the Dynamical Evolution of an Axially Symmetric Quasar Model
Galaxies: orbits regular and chaotic motion
2009/5/7
The role of the angular momentum in the regular or chaotic
character of motion in an axially symmetric quasar model is examined.
It is found that, for a given value of the critical angular momentum ...
AN ALTERNATIVE MASS MODEL FOR GALACTIC DARK CORONAE
AN ALTERNATIVE MASS MODEL GALACTIC DARK CORONAE
2009/3/16
A spherically symmetric mass distribution with two scale parameters
for the dark corona of a (spiral) galaxy as an alternative to the usually applied
quasi-isothermal sphere is considered. Examinati...
