Concerning colour: the effect of environment on type ia supernova colour in the dark energy survey

HIGHLIGHTS

• who: Kelsey L. et al. from the (UNIVERSITY) have published the paper: Concerning colour: The effect of environment on type Ia supernova colour in the dark energy survey, in the Journal: (JOURNAL)
• what: The authors further examine the idea that blue SNe Ia are more homogeneous by studying the differences in Hubble residual for subsets of SNe Ia divided by SN colour, using photometrically confirmed SNe Ia from the Dark Energy Survey (DES) SN programme (DES-SN) five-year cosmological sample. As in K21, the authors focus the analysis on rest-frame U - R. The . . .
