摘要:
A 20 ksec ROSAT PSPC observations of the cluster of galaxies Abell 1795 was used to perform a spatially resolved, spectral model fit, permitting a non‐parametric determination of the de‐projected radial temperature and density distribution (Figs. a, b). We derive the radial distribution of gravitating, gas, and galaxy mass (Fig. c), the dark‐to‐visible mass fraction, and determine the cooling time (Fig. e) and cooling flow. ©1994 American Institute of Physics
