Stellar velocity dispersion and initial mass function gradients in dissipationless galaxy mergers
Carlo Nipoti, Carlo Cannarozzo, Francesco Calura +2
The stellar initial mass function (IMF) is believed to be non-universal among early-type galaxies (ETGs). Parameterizing the IMF with the so-called IMF mismatch parameter $α_{\rm I…

The merger-driven evolution of massive early-type galaxies
Carlo Cannarozzo, Carlo Nipoti, Alessandro Sonnenfeld +4
The evolution of the structural and kinematic properties of early-type galaxies (ETGs), their scaling relations, as well as their stellar metallicity and age contain precious infor…

The cosmic evolution of the stellar massvelocity dispersion relation of early-type galaxies
Carlo Cannarozzo, Alessandro Sonnenfeld, Carlo Nipoti
We study the evolution of the observed correlation between central stellar velocity dispersion and stellar mass of massive ($M_*\gtrsim 3\times 10^{10}\,\mathr…
