Multi-wavelength Surveys for Distant Clusters | | Marc Postman
; | | Date: |
13 Nov 2001 | | Subject: | astro-ph | | Abstract: | Given the importance of clusters to the fields of cosmology and galaxy evolution, it is critical to understand how the cluster detection process affects (biases) ones scientific conclusions derived from a given cluster sample. I review the astrophysics, algorithms, and observational constraints that must be considered when attempting to assess cluster selection biases and their impact on the scientific constraints derived from multi-wavelength cluster surveys. In particular, one can more accurately quantify and understand the selection biases and assess cluster evolution when using joint optical/NIR/x-ray surveys than can be achieved when employing any single cluster survey. | | Source: | arXiv, astro-ph/0111247 | | Services: | Forum | Review | PDF | Favorites | |
