Our research focuses on studies of the expansion history of the Universe. We use mainly Type Ia supernovae as distance indicators and we were involved in the discovery of dark energy, which we now know makes up the majority of the energy density of the Universe. The accuracy on these measurements depends on our understanding of the intrinsic properties of Type Ia supernovae, as well as effects affecting the amount of light reaching us at Earth, e.g., dimming by dust and magnification by gravitational lensing. Our findings in all these areas can be found through the links above.
