The Impact of Supernovae of Type Ia on Large Scales through the Secular Evolution of their Rate
Laura Greggio
A straightforward formalism to evaluate the impact of Type Ia Supernovae on large scale astrophysical issues is presented, together with analytical formulations for the SNIa rate f…
Comparing the old Stellar Population in Globulars and Dwarf Galaxies: The Cases of Phoenix and Leo A
Ulrich Hopp, Laura Greggio
Due to their star formation history (SFH), the stellar population in Dwarf Galaxies (DG) is likely to have a metallicity spread which is best traced by the morphology of the Red Gi…
The Color-Magnitude Diagram of composite stellar populations
L. Greggio
The theoretical relation between the number of post main sequence stars from stellar populations and their total mass in investigated. This is used to derive some basic relations b…
The evolution of the color gradients of early-type cluster galaxies
R. P. Saglia, C. Maraston, L. Greggio +2
We investigate the origin of color gradients in cluster early-type galaxies to probe whether pure age or pure metallicity gradients can explain the observed data in local and dista…
Stellar yields and chemical evolution - The solar neighborhood as a calibrator
Daniel Thomas, Laura Greggio, Ralf Bender
Uncertainties in stellar nucleosynthesis and their impact on models of chemical evolution are discussed. Comparing the Type II supernova nucleosynthesis prescriptions from Woosley…
Probing early-type galaxy evolution with the Kormendy relation
B. L. Ziegler, R. P. Saglia, R. Bender +3
We investigate the evolution of early-type galaxies in four clusters at z=0.4 (Abell370, Cl0303+17, Cl0939+47 and Cl1447+26) and in one at z=0.55 (Cl0016+16). The galaxies are sele…
