HIFLUGCS: Galaxy cluster scaling relations between X-ray luminosity, gas mass, cluster radius, and velocity dispersion
Cosmology observations (Cosmology:) dark matter Galaxies clusters
2011/1/5
We present relations between X-ray luminosity and velocity dispersion (L − ), X-ray luminosity and gas mass (L − Mgas), and cluster radius and velocity dispersion (r500 − ) for 62 ...
The imprint of the interaction between dark sectors in galaxy clusters
dark sectors galaxy clusters
2010/3/17
Based on perturbation theory, we study the dynamics of how dark matter and dark energy in the collapsing system approach dynamical equilibrium while interacting. We find that the interaction between d...

Cosmology gravitation galaxies Clustering method Analytical
2010/4/9
The description of gravitational galaxy clustering evolving through quasi-equilibrium thermodynamics is examined on the basis of thermodynamic fluctuations and statistical mechanical ensemble techniqu...
