Abstract
We present an investigation of the Abell 14 galaxy cluster, including a discussion of subclustering, some aspects concerning its evolution, as well as an analysis of galaxy orientations in the cluster region. We confirm the previous results showing evidence for subclustering in this cluster obtained from studies of galaxy distributions. In this light, our aim has been to examine non-random effects in the galaxy orientations in rich clusters, with particular regard to the presence of subclustering. Our results do provide evidence for non-random alignment of the galaxies in Abell 14 and confirm the presence of subclustering within this cluster. However, the direction of the alignment is different from that (we) found for Abell 754 (Godlowski et al. 1998). We continue our investigations by studying other clusters in a similar manner. The results will be published in the next paper.

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.
