Abstract:

We present long slit spectra for a magnitude limited sample of 35 E and S0 galaxies of the Coma cluster. The high quality of the data allowed us to derive spatially resolved spectra for a substantial sample of Coma galaxies for the first time. From these spectra we obtained rotation curves, the velocity dispersion profiles and the H₃ and H₄ coefficients of the Hermite decomposition of the line of sight velocity distribution. Moreover, we derive the radial line index profiles of Mg, Fe and H ${\beta}$ line indices out to $R\approx 1 r_{\rm e} - 3 r_{\rm e}$ with high signal-to-noise ratio. We describe the galaxy sample, the observations and data reduction, and present the spectroscopic database. Ground-based photometry for a subsample of 8 galaxies is also presented.

The Coma cluster is one of the richest known clusters of galaxies, spanning about 4 decades in density. Hence it is the ideal place to study the structure of galaxies as a function of environmental density in order to constrain the theories of galaxy formation and evolution. Based on the spectroscopic database presented, we will discuss these issues in a series of future papers.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
