Investigation of galaxies in and near the cluster A1185

Results of optical, radio, and submillimeter studies of the nearby galaxy c luster A1185 are presented. Coordinates have been obtained for 115 galaxies that are either cluster members or field galaxies in the direction of A118 5. Radio spectra for a number of galaxies in this cluster have been derived using observations on the RATAN-600 radio telescope at 2.7, 3.9, 7.6, 13, and 31 cm, together with data published in other studies. At the cluster ce nter, some of the galaxies have either flat or inverted spectra. The vast m ajority of the galaxies display a uniform brightness distribution; i.e., th ey do not show any signs of structure. Sixty-four percent of the galaxies a re elliptical, and 31% are spherical. The total number of blue galaxies is 22%.
