A new estimate for the dispersion velocity of galactic dark matter particles
发表期刊CHINESE PHYSICS LETTERS
关键词Quasar-galaxy Associations
摘要An independent method is proposed to estimate the dispersion velocity of galactic dark matter particles. This method is based on the observed quasar-galaxy association samples that are caused by gravitational lensing. All resulting dispersion velocities are much higher than similar to 220 km.s(-1), a value expected from the virial theorem, which shows that the conventional assumption of virialization may be invalid in the halo regions of galaxies.
