Star-formation rates in the nuclei of violently interacting galaxies.
Abstract
It has now been recognized that galaxy-galaxy interactions represent an important evolutionary process in many extragalactic systems, taking into account large-scale star-formation bursts, Seyfert activity, and QSO phenomena. The present paper provides results of a spectrophotometric survey of the nuclear regions of a large sample of violently interacting galaxies. Attention is given to sample selection, observational procedures and data reduction, data analysis, aspects of spectral classification, ionization mechanisms, emission-line strengths, correlations with integral properties, comparisons with other studies, and a comparison with theoretical models.
