      The rest-frame $(g–r) /M_r$ color–magnitude relations of 12 Abell-type clusters are analyzed in the redshift range ($0.02\lesssim z \lesssim 0.10$) and within a projected radius of 0.75 Mpc using photometric data from SDSS-DR9. We show that the color–magnitude relation parameters (slope, zero-point, and scatter) do not exhibit significant evolution within this low-redshift range. Thus, we can say that during the look-back time of $z \sim 0.1$ all red sequence galaxies evolve passively, without any star formation activity.

    • Continuous Article Publication

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
