Mid-Infrared Recalibration of Extragalactic Distance Scale

Learn about the Carnegie Hubble Program's recalibration of the extragalactic distance scale using mid-infrared data, emphasizing Cepheid light curves. Led by Wendy Freedman, the project explores the properties of basic Cepheid light curves in various galaxies. Published research includes insights on Ceph LMC mid-IR data and the dominance of carbon stars in NGC 4258. Dive into this comprehensive study today!
