Description
Understanding how galaxies form and assemble is one of the central goals of astrophysics. By extracting detailed elemental abundance patterns and constraining the stellar initial mass function (IMF) from the integrated light of distant galaxies, we gain new insights into their star formation histories, stellar mass distributions, and dark matter content. In this talk, I will present results from the MASSIVE Survey on the stellar IMF and its spatial variations in nearby massive early-type galaxies. I will discuss the observed trends and their implications for the physical mechanisms that shape the IMF and drive the formation and assembly of the most massive galaxies in the local Universe.
