Type Ia SN Light Curve Fitting
Type Ia supernova light curve fitting is a technique for measuring cosmic distances by observing the brightness evolution of thermonuclear explosions in binary star systems. Developed systematically by Mark Phillips in 1993, this method revealed that SNe Ia can be standardized to provide precise distance measurements, playing a central role in the discovery of cosmic acceleration and dark energy.
