New EVN images at 5.0 GHz and 8.4 GHz of ON 231 confirm the complex structure of the source, the identification of the core, the presence of components on the two sides of the core…
The mass distribution in early type disk galaxies
E. Noordermeer, J. M. van der Hulst, R. Sancisi +2
We are studying the mass distribution in a sample of 50 early type spiral galaxies, with morphological type betweens S0 and Sab and absolute magnitudes M_B between -18 and -22; the…
Chemical evolution and nature of Damped Lyman-Alpha systems
