个人简介
Mariangela Bernardi is a Professor in the Department of Physics and Astronomy at the University of Pennsylvania. Her work has focused on the analysis of galaxies properties and their environment to understand their formation and evolution, and on the co-evolution of galaxies and super-massive black holes. She has also done some work on large-scale structures, peculiar motions, QSOs and the Ly-alpha forest. Earlier on in her career she assembled, maintained and analyzed the ENEAR database used for peculiar velocity studies; it is still the only all-sky early-type galaxy database. She demonstrated that chemical compositions of early-type galaxies in the ENEAR sample show little dependence on environment. She has been involved with the SDSS for two decades. She is acknowledged as a `Builder' of the Sloan Digital Sky Survey (SDSS). She used the SDSS to assemble and analyze what was at the time the world's largest catalog of early-type galaxies, and used it to demonstrate that velocity dispersion is the key physical parameter which determines galaxy properties. Her work showed that a shift in paradigm was needed: minor rather than major mergers must have been an important assembly mechanism for the most massive galaxies. She also published work on the IGM and quasars at intermediate and high redshift.
