Starbursts versus Truncated Star Formation in Nearby Clusters of Galaxies
James A. Rose, Alejandro E. Gaba, Nelson Caldwell +1
We present long-slit spectroscopy, B and R bandpass imaging, and 21 cm observations of a sample of early-type galaxies in nearby clusters which are known to be either in a star-for…
47 Tuc: The Spectroscopic Versus CMD Age Discrepancy
Alexandre Vazdekis, Maurizio Salaris, Nobuo Arimoto +1
We investigate current problems in obtaining reliable ages for old stellar systems based on stellar population synthesis modelling of their integrated spectra. In particular, we ad…
Spectral Variations in Early-Type Galaxies as a Function of Mass
K. D. Concannon, J. A. Rose, N. Caldwell
We report on the strengths of three spectral indicators - Mg_2, Hbeta, and Hn/Fe - in the integrated light of a sample of 100 field and cluster E/S0 galaxies. The measured indices…
