Galaxy bulges as a research area focuses on the formation, structure, dynamics, and stellar populations of the central spheroidal components of disk galaxies, and their role in galaxy evolution. This field investigates bulge types (classical vs. pseudobulges), scaling relations with supermassive black holes, star formation histories, chemical enrichment, and kinematical properties using photometric decomposition, integral-field spectroscopy, and cosmological simulations. Researchers study how processes such as mergers, secular evolution, bar-driven inflows, and feedback shape bulge mass, morphology, and angular momentum, constraining models of hierarchical structure formation and the co-evolution of bulges and their host dark matter halos.
