Scientific paper

The High-Z SN Search is an international collaboration to find and follow Type Ia Supernovae to redshift of z = 1. We present observations of more the 20 SNe at z > 0.3 which have been observed in restframe B and V. Distances derived to these objects, when compared to a nearby sample, indicate the Universe is currently acceleratining in its rate of expansion, and indicate that a Cosmological Constant (or other form of exotic energy/matter) is required to explain the observations.
