Abstract |
During the last two decades, Type Ia supernovae became the main tool to study the expansion history of the Universe and provided the first solid evidence for the accelerated expansion rate in the late 1990's. Since then, the focus for observational cosmology shifted towards trying to establish if the "dark energy" driving the accelerated expansion is constant in time and space, i.e., consistent with Einstein's cosmological constant, Lambda. The current observational constraints on deviations from Lambda will be presented, as well as ongoing efforts aiming at reducing key systematic uncertainties, limiting the precision of Type Ia supernovae as distance indicators. |
