Brown, and Gautham Narayan: The Changing Fractions of Type Ia Supernova NUV--Optical Subclasses with Redshift, The Astrophysical Journal 803,1 (2015) 20- The "type IA supernova standard candles" that were used to win Nobel pries, prove the universe is accelerating expansion, due to (apparently) Einstein cosmical constant "Lambda," etc, etc... ...aren't. That is, UV observations now show there really are two classes of these candles, which erroneously were lumped into one basket -- and more seriously, one class predominates nearer to us, the other, further. Hence, all that work is now called into question and presumably needs to be entirely redone, and the probable conclusion will be that there is a lot less Lambda than they thought. -- Warren D.
