This paper discusses the stellar population content of distant (5 000kms−1 VR 16 000kms−1) galaxies with enhanced star-formation activity. Distinction is made between isolated galaxies and galaxies morphologically disturbed, with clear signs of i

As part of a systematic study of the UV properties of galaxies in the IUE library,we present in this paper an analysis of nuclear stellar populations in spiral galaxies with radial velocity ≤ 5 000kms-ˡ. In this sample of 60 galaxies the IUE apert

We study the UV turnup in early-type galaxies from coadded IUE spectra reaching an unprecedented signal to noise ratio. Some spectral groups resulted with strong or moderate UV turnup, while in others it is very weak or absent. We study the relations

We present the data and initial results from a combined HST/IUE/ground-based spectroscopic monitoring campaign on the Seyfert I galaxy NGC 5548 that was undertaken in order to address questions that require both higher temporal resolution and higher

The star clusters G 158 and G 177, located at projected distances smaller than 1.5 kpc from the semi-stellar nucleus of M 31, show spectra extreme in absorption-line strengths, comparable to those from the nuclei of giant ellipticals or from the M 31
