Observational cosmology is currently experiencing a revolution. Resent measurements of mangitudes vs redshift of very distant type Ia supernovae indicate that the rate of expansion of the universe is increasing. This acceleration requires the existen

The AMANDA high energy neutrino telescope has successfully been increased in size from four detector strings to ten detector springs during the 1996/1997 season. The first upward going muon-neutrino candidates have been reconstructed from the 1996 ye

We have developed a new tool for measurement of the cosmological parameters: a systematic search-and-study technique for high-redshift supernovae. In the first years of this Supernova Cosmology Project, we have discovered over 27 supernovae. Using a

Alhough there is little doubt at present that the redshift of distant galaxies is due to an expansion of the universe, we present in this paper a direct confirmation for the cosmological expansion. This work is based on the first results from a syste

We have begun a program to discover high-redshift supernovae ( z ≈ 0.2–0.6), and study them with follow-up photometry and spectroscopy. We report here our first discovery, a supernova at z = 0.458 (SN1992bi) and the ongoing analysis on several ne

We report the first results of the AMANDA detector. During the antarctic summer 1993-94 four strings were deployed between 0.8 an 1 km depth, each equipped with 20 photomultiplier tubes (PMTs). A laser source was used to investigate the optical prope
