Universal scaling laws and density slope for dark matter haloes
Zhijie Xu
Small scale challenges suggest some missing pieces in our understanding of dark matter. A cascade theory for dark matter is proposed to provide extra insights, similar to the casca…
The baryonic-to-halo mass relation from mass and energy cascade in self-gravitating collisionless dark matter flow
Zhijie Xu
The relation between properties of galaxies and dark matter halos they reside in can be valuable for structure formation and evolution. This paper focus on the baryonic-to-halo mas…
On a critical acceleration scale of dark matter in Lambda-CDM and dynamical dark energy
Zhijie, Xu
Universal acceleration emerges in various empirical laws, yet its fundamental nature remains unclear. Using Illustris and Virgo N-body simulations, we propose is the sc…
On the statistical theory of self-gravitating collisionless dark matter flow: Scale and redshift variation of velocity and density distributions
Zhijie Xu
This paper studies the scale and redshift variation of density and velocity distributions in self-gravitating collisionless dark matter flow by a halo-based non-projection approach…
Evolution of energy, momentum, and spin parameter in dark matter flow and integral constants of motion
Zhijie Xu
N-body equations of motion in comoving system and expanding background are reformulated in a transformed system with static background and fixed damping. The energy and momentum ev…
On the statistical theory of self-gravitating collisionless dark matter flow: high order kinematic and dynamic relations
Zhijie Xu
To better understand the collisionless dark matter flow on different scales, statistical theory involving kinematic and dynamic relations must be developed for different types of f…
