Relating Galaxy Cluster X-Ray Luminosities to Gravitational Masses in Wide Angle Surveys
arXiv:astro-ph/0010575 · doi:10.1007/10849171_20
Abstract
It is shown that galaxy cluster surveys selecting clusters by their X-ray luminosity effectively select by cluster mass. It is shown that a selection based solely on Abell galaxy richness is less efficient in terms of mass. Furthermore the empirical X-ray luminosity - gravitational mass relation and its scatter is quantified and the relation is compared to predicted relations.
