Galaxy Clusters in the IRAC Dark Field. I. Growth of the Red Sequence
Galaxy Clusters in the IRAC Dark Field. I. Growth of the Red Sequence
Using three newly identified galaxy clusters at z ∼ 1 (photometric redshift) we measure the evolution of the galaxies within clusters from high redshift to the present day by studying the growth of the red cluster sequence. The clusters are located in the Spitzer Infrared Array Camera (IRAC) Dark Field, …
