16 Aug 2001 | | Subject: | astro-ph | | Affiliation: | UCSC), Anthony H. Gonzalez (CfA), Dennis Zaritsky (Arizona), Julianne J. Dalcanton (U. Washington | | Abstract: | (Abridged) We analyze photometry and spectroscopy of a sample of 63 clusters at 0.3~ 5) and in which many of these galaxies, if not all, accrete mass either in the form of evolved stellar populations or gas that causes only a short term episode of star formation at lower redshifts (1.5 < z < 2). Our data are too crude to reach conclusions regarding the evolutionary state of any particular cluster or to investigate whether the morphological evolution of galaxies matches the simple scenario we discuss, but the statistical nature of this study suggests that the observed evolutionary trends are universal in massive clusters. | | Source: | arXiv, astro-ph/0108279 | | Services: | Forum | Review | PDF | Favorites | |
