"The Texas SuperNova Search"


Supernovae (SNe) are popular tools to explore the cosmological expansion
of the Universe owing to their bright peak magnitudes and reasonably high
rates;  however, even the relatively homogeneous Type Ia supernovae are
not perfect standard candles intrinsically. Their absolute peak brightness
must be established by corrections that have been largely empirical.
Hundreds of SNe are now found every year, shrinking the statistical
errors in the cosmological terms, but most of these distant discoveries do
little to further the physical understanding of SNe, which may illuminate
unknown systematics.
