High-redshift supernovae are an important tool for measuring the
cosmological parameters Ømega_0, \Lambda, and Ømega_k
that describe our expanding
universe. We have shown that the rare, random, and transient supernovae can
be systematically detected and studied at high redshifts. So far, we have
discovered and studied over 28 supernovae at redshifts z = 0.35 -- 0.85,
and identified most of these as Type Ia supernovae.
We present our measurements of cosmological parameters
and discuss other cosmological implications derived from the spectra and
multi-band light curves of our supernovae.
