" The dominance of quenching through cosmic times "

Alvio Renzini

(Astronomical Observatory of Padova)

The evolution with cosmic time of the star formation rate density (the Lilly-Madau plot) and of the "Main Sequence" star formation rate--stellar mass relation are two well established observational facts. In this seminar the implications of these two relations combined are analytically explored, showing that quenching of star formation must start already at very early cosmic times and the quenched fraction then dominates ever since over the star forming one. Thus, a simple picture of the cosmic evolution of the global star formation rate density is derived, in terms of the interplay between star formation and its quenching.

Seminars are also held at JAC, CFHT, and IfA.
