Effect of Ion Dynamics on the Evolution of Electron Phase-space Holes
Ion dynamics Electron holes Transverse instability Magnetized plasma
2013/7/15
The evolution of two-dimensional (2D) electron phase-space holes (electron holes) has been previously investigated with electrostatic Particle-in-Cell (PIC) simulations, which neglect ion dynamics. Th...
Structure in phase space associated with spiral and bar density waves in an N-body galactic disk
bar density waves N-body galactic disk
2010/11/30
An N-body simulation of a Galactic disk is used to study the stellar phase space distribution or velocity distributions in different local neighborhoods. Pattern speeds identified in Fourier spectrogr...
Warm dark matter at small scales: peculiar velocities and phase space density
Warm dark matter small scales peculiar velocities phase space density
2010/11/11
We study the scale and redshift dependence of the power spectra for density perturbations and
peculiar velocities, and the evolution of a coarse grained phase space density for (WDM) particles that d...

2010/10/4
Agegraphic dark energy, has been recently proposed, based on the so-called Karolyhazy uncertainty relation, which arises from quantum mechanics together with general relativity. In the first part of t...
The universal distribution of halo interlopers in projected phase space. Bias in galaxy cluster concentration and velocity anisotropy?
Galaxies clusters general Cosmology miscellaneous (Cosmology) dark matter Galaxies halos Gravitational lensing weak Methods numerical
2010/2/26
When clusters of galaxies are viewed in projection, one cannot avoid picking up foreground/background interlopers, that lie within the virial cone (VC), but outside the virial sphere. Structural and k...

2005/12/31
An analysis of the solutions for the field equations of generalized scalar-tensor theories of gravitation is performed through the study of the geometry of the phase space and the stability of the sol...
