Environmental dependence of X-ray and optical properties of galaxy
  clusters
  Galaxy clusters are widely used to constrain cosmological parameters through
their properties, such as masses, luminosity and temperature distributions. One
should take into account all kind of biases that could affect these analyses in
order to obtain reliable constraints. In this work, we study the difference in
the properties of clusters residing in different large scale environments,
defined by their position within or outside of voids, and the density of their
surrounding space. We use both observational and simulation cluster and void
catalogues, i.e. XCS and redMaPPer clusters, BOSS voids, and Magneticum
simulations. We devise two different environmental proxies for the clusters and
study their redshift, richness, mass, X-ray luminosity and temperature
distributions as well as some properties of their galaxy populations. We use
the Kolmogorov-Smirnov two-sample test to discover that richer and more massive
clusters are more prevalent in overdense regions and outside of voids. We also
find that clusters of matched richness and mass in overdense regions and
outside voids tend to have higher X-ray luminosities and temperatures. These
differences could have important implications for precision cosmology with
clusters of galaxies, since cluster mass calibrations can vary with
environment.
