X-ray luminosity-velocity dispersion relation
Listed in IVOA Registry (Virtual Observatory)
We demonstrate that individual elliptical galaxies and clusters of galaxies form a continuous X-ray luminosity-velocity dispersion (L_X_-{sigma}) relation.
Description
Our samples of 280 clusters and 57 galaxies have L_X_ {prop.to}{sigma}^4.4^ and L_X_{prop.to}{sigma}^10^, respectively. This unified L_X_-{sigma} relation spans 8 orders of magnitude in L_X_ and is fully consistent with the observed and theoretical luminosity-temperature scaling laws.
Our results support the notion that galaxies and clusters of galaxies are the luminous tracers of similar dark matter halos.
