E+S galaxy pairs: are they the precursors of fossil groups?
R. Grützbauch, F. Annibali, R. Rampazzo +1
Galaxy pairs may represent a way station in the evolutionary path from poor groups to giant isolated ellipticals (or fossil groups). To test this evolutionary scenario, we investig…
The nature of ionized gas in early-type galaxies
F. Annibali, A. Bressan, R. Rampazzo +1
We present a study of the ionized gas in a sample of 65 nearby early-type galaxies, for which we have acquired optical intermediate-resolution spectra. Emission lines are detected…
Small-scale systems of galaxies. IV. Searching for the faint galaxy population associated with X-ray detected isolated E+S pairs
R. Grützbauch, W. W. Zeilinger, R. Rampazzo +3
In hierarchical evolutionary scenarios, isolated, physical pairs may represent an intermediate phase, or "way station", between collapsing groups and isolated elliptical (E) galaxi…
