Discovery of the most distant supernovae and the quest for {Omega}
A search for cosmological supernovae has discovered a number of a type Ia supernovae. In particular, one at z = 0.458 is the most distant supernovae yet observed. There is strong evidence from measurements of nearby type Ia supernovae that they can be considered as {open_quotes}standard candles{clos...
