New study says stellar mass of galaxies does not contain all the information about other galactic properties, refuting a major presumption in astronomy
Cosmologists from Visva-Bharati University and Osmania University reported that the stellar mass of galaxies does not encode all of the information about other galactic properties, an assumption long thought to be true. The new study used archival data from the SDSS in conjunction with cosmological simulations to come to this groundbreaking conclusion. An artist’s impression of the Milky Way galaxy. Photograph: Chen Xiaodian. Downloaded from: The Guardian Understanding the formation and evolution of galaxies is undoubtedly one of the major goals of modern cosmology. The integrated stellar mass of a galaxy is thought to be the most fundamental property which largely influences its structure and evolution. It is often taken as an impression of its formation h...
