The mechanism proposed by Kormendy (1984) for the formation of counterrotating cores in elliptical galaxies is investigated using self-consistent numerical...

BVRI surface photometry is presented for the interacting galaxy pair Arp 86 (NGC 7753-7752). Deep high-resolution images were obtained in order to study the...

New long-slit optical spectroscopy and optical and NIR images of NGC 520 are presented. Velocity-dispersion and radial-velocity profiles are obtained from the...

The peculiar galaxy NGC 520 (Arp 157) is often interpreted as an interacting pair of galaxies. The identification of the two bulges and overall morphology of...

This paper describes results obtained on a simulation of two high-velocity encounters of NGC 4782/4783 and NGC 2672/2673 binary elliptical galaxies which differ...

Two sources selected from the IRAS Point Source Catalogue (PSC) have been spectroscopically identified as galaxies with a Seyfert type active nucleus. The...
