Biography

Marshall McCall is a Professor Emeritus specializing in Astronomy and Astrophysics. His research focuses on the formation, evolution, and structure of galaxies, particularly the aggregates of galaxies such as the Local Sheet analogues. He investigates interstellar matter, with a particular interest in gaseous nebulae, which includes planetary nebulae and HII regions. His work aims to elucidate the mechanisms driving the evolution of galaxies by utilizing gaseous nebulae to probe chemical compositions. McCall employs surface photometry, particularly near-infrared wavelengths, combined with dynamical measurements, to develop a unified description of normal galaxies. His research has significantly advanced our understanding of the Cosmic Web and has improved methodologies for determining distances to galaxies. Recently, his precise three-dimensional map of Local Sheet galaxies has revealed that the development of the Milky Way galaxy has been influenced by its environment to a far greater extent than previously recognized. Additionally, McCall’s research into individual galaxy structures facilitates insights regarding the origin, spin nature, localization, and the prevalence of dark matter in the universe.
