Are High Z SNe Brighter than LCMD Predicts?

  1. Oct 16, 2014 #1
    I've read one or two articles that are a little dated (2009) and having some trouble finding a thread that discussed the matter briefly. I know that SN US02Wil is bright (for its distance). Is anyone aware of any studies that show that SNe with a high Z appear to be brighter than LCDM predicts?

    No.

    There are some rare events that look way too bright, but there's no systematic tendency. The vast majority of supernovae fall in line with the expected redshift-brightness relationship, and those few that don't can generally be explained as not actually being SN-1A events, or as due to chance alignments.
