Abstract:
A precise understanding of the relations between observable X-ray
properties of galaxy clusters and cluster mass is a vital part of the
application of X-ray galaxy cluster surveys to test cosmological
models. An understanding of how these relations evolve with redshift
is just emerging from a number of observational data sets.
The current literature provides a diverse and inhomogeneous picture of
scaling relation evolution. We attempt to transform these results and
the data on recently discovered distant clusters into an updated and
consistent framework, and provide an overall view of scaling relation
evolution from the combined data sets.
We study in particular the most important scaling relations connecting
X-ray luminosity, temperature, and cluster mass (M-T, LX-T, and
M-LX) combining 14 published data sets supplemented with recently
published data of distant clusters and new results from follow-up
observations of the XMM-Newton Distant Cluster Project (XDCP) that
adds new leverage to efficiently constrain the scaling relations at
high redshift.
