概要:
Cosmological implications of clusters of galaxies are discussed with
particular attention to their importance in probing the cosmological
parameters. As an important step toward
breaking the degeneracy among the viable cosmological models, we
observed the most luminous X-ray cluster RXJ1347-1145 in three bands
(21 and 43 GHz in the Nobeyama Radio Observatory, Japan, and 350 GHz
in the J. C. Maxwell telescope at Mauna Kea, Hawaii). We report on
the preliminary results which are in good agreement with the profile
of the Sunayev -- Zel'dovich effect predicted on the basis of the
previous X-ray observation of the cluster.
