Type Ia
The Supernova Cosmology Project
Our Type Ia SNe research program discovered dark energy in the late 1990s and continues to study SNe from ground- and space-based telescopes to improve the measurement of dark energy and extend it to higher redshifts. Over the next decade, we will
be developing a program using Rubin Observatory’s Legacy Survey of Space and Time (LSST) to identify SNe that can be subsequently observed with other telescopes in order to obtain spectroscopic typing and redshifts. The spectroscopic follow-up will provide a well-calibrated, precision sample for probing dark energy.
