PB 9493-9494 intertacting galaxies: The correlation of IRAS sources with close pairs of PB UVe objects.

REBOUL H. and VANDERRIEST C.

Abstract (from CDS):

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.
