Cosmology with Supernovae… and Kilonovae!

In this talk, I will present new analyses of Type Ia Supernovae that mark the most precise measurement of dark energy to date. I will go over how this analysis ties together with the analysis of the local value Hubble constant, for which tension persists with inferred value from the CMB. I will then discuss the first measurements of the Hubble constant with kilonovae and gravitational waves. I will review the large amount of overlap between the issues that must be tackled for future progress using supernovae or kilonovae to measure cosmological parameters, and discuss future opportunities.
