Diffuse elliptical galaxies, the first 3D spectroscopic observations
Igor Chilingarian, Philippe Prugniel, Olga Silchenko +1
Diffuse elliptical galaxies (or dwarfs) are the numerically dominant population in clusters like Virgo and Fornax. They carry only a few percent of the baryonic mass but are very s…
Virtual instrumentation to study galaxies
Ph. Prugniel, I. Chilingarian, H. Flores +7
The MIGALE project (http://www.sai.msu.su/migale) provides databases and data analysis tools to study the evolution of galaxies from z=1 to z=0. It develops and maintain a general…
Hypercat : A Database for extragalactic astronomy
Ph. Prugniel, G. Maubon
The Hypercat Database is developed at Observatoire de Lyon and is distributed on the WEB through different mirrors in Europe. The goal of Hypercat is to gather data necessary for s…
Effect of the large scale environment on the internal dynamics of early-type galaxies
G. Maubon, Ph. Prugniel
We have studied the population-density relation in very sparse environments, from poor clusters to isolated galaxies, and we find that early-type galaxies with a young stellar popu…
