From Correlations of Galaxy Properties to the Physics of Galaxy Formation: A Theoretical Framework
Alberto Conti, Barbara S. Ryden, David H. Weinberg
(Abridged) Motivated by forthcoming data from the Sloan Digital Sky Survey, we present a theoretical framework that can be used to interpret Principal Component Analysis (PCA) of d…
The Morphological Evolution of Merger Remnants
Barbara Ryden, Jeremy Tinker
Elliptical galaxies formed in a major merger tend to become more nearly spherical with time, thanks to the gravitational effect of their central black hole (or black holes). Observ…
Structural evolution in elliptical galaxies: the age-shape relation
Barbara S. Ryden, Duncan A. Forbes, A. I. Terlevich
We test the hypothesis that the apparent axis ratio of an elliptical galaxy is correlated with the age of its stellar population. We find that old ellipticals (with estimated stell…
