Goal of the Supernova hub
High redshift observations of Type Ia Supernovae (SN) provided the first convincing evidence for the existence of Dark Energy (DE). These observations remain one of the most useful tools for constraining cosmological parameters. Despite numerous advances in observational and theoretical techniques towards understanding Type Ia SN, there remain many potential systematic uncertainties that can limit the cosmological precision obtainable from SN surveys. These systematic uncertainties have become the limiting factor in SN constraints on DE. It is the goal of the Supernova Hub to carry out a research program to understand and reduce these potential systematic errors, thereby improving SN as cosmological probes.
