Early-type galaxies as a research area focuses on the observational and theoretical study of elliptical and lenticular (S0) galaxies, emphasizing their stellar populations, dynamics, morphologies, and formation and evolution pathways. This field investigates their typically red, old, and metal-rich stellar content; the role of mergers, quenching, and environmental effects in shaping their properties; and the structure and kinematics of their stars, gas, dark matter, and central supermassive black holes. Research integrates multiwavelength observations, integral-field spectroscopy, and cosmological simulations to constrain scaling relations, mass assembly histories, and the physical mechanisms driving morphological transformation in the galaxy population.
European astronomers have used the Atacama Large Millimeter Array (ALMA) and the James Webb Space Telescope (JWST) to observe a recently discovered giant disk galaxy known as ADF22.1. Results of the new observations, published ...
Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that analyzes the motion of two nearby galaxy groups within their surrounding cosmic flow. The results ...
