Color–Magnitude and Luminosity Function in Galaxy Clusters

Mariwan A. Rasheed, Mohamad A. Brza

Abstract :

We present a study of the color-magnitude diagram of H_I Parks All Sky Survey HIPASS of faint H_I selected galaxies contain faint gas-rich, and a scatter plot of HIPASS of faint galaxies. The HIPASS of faint galaxies that contains gas fraction at absolute V-band magnitudes is shown. Also the surface ightness of HIPASS of faint galaxies ighter than M_v=-12.55 and the scale length which determine the morphological structure of galaxies are shown. Some of the galaxy clusters detected at 15μm, and some others detected at 6.75μm which are ighter and more luminous. The size of the galaxy clusters depends on the energy radiated by the galaxies detected at 15μm and the energy radiated by the galaxies detected at 6.75μm, and some of the clusters are active to star formation. The luminosity function of the clusters is proved to be old, more luminous and have the reddest galaxies. The color distribution of the clusters are shown which contain larger number of galaxies at b-v=0.4 and r-i=0.6.
