Properties of the Environment of Galaxies in Clusters of Galaxies CL
  0024+1654 and RX J0152.7-1357
  We report the results of combined analyses of X-ray and optical data of two
galaxy clusters, CL 0024$+$1654 and RX J0152.7$-$1357 at redshift $z = 0.395$
and $z = 0.830$, respectively, which offer a holistic physical description of
the two clusters. Our X-ray analysis yields temperature and density profile of
the gas in the intra-cluster medium (ICM). Using optical photometric and
spectroscopic data, complemented with mass distribution from gravitational
lensing study, we investigate any possible correlation between the physical
properties of the galaxy members, i.e., their color, morphology, and star
formation rate (SFR) with their environments. We quantify the properties of the
environment of each galaxy by galaxy number density, ICM temperature, and mass
density. Although our result shows that the two clusters exhibit a weaker
correlation compared to relaxed clusters, it still confirms the significant
effect of the ICM on the SFRs in the galaxies. The closer relation between
galaxy physical property and the condition of its immediate environment found
in this work indicates the locality of galaxy evolution, even within a larger
bound system such as cluster. Various physical mechanisms are suggested to
explain the relation between the properties of galaxies and their environment.
