Abstract
The cross-correlation of close pairs of UV-excess objects from the Berger-Fringant catalogue with IRAS sources supplies three cases. The first two are already known objects. We study in detail the most interesting (and new) case: PB 9493-9494. Optical observations in direct imaging and in integral field spectrography confirm that this system is a pair of strongly interacting galaxies with starbursts and show the complex structure of an evolved but not merged encounter. Although such an evolution step is only intermediate, the brightest nucleus (PB 9494) may be on the verge of becoming an AGN. We discuss the peculiarities of this system with regard to optical versus far infrared behaviour, in connection with its special mode of selection.

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.
