A HUBBLE DIAGRAM FROM TYPE II SUPERNOVAE BASED SOLELY ON PHOTOMETRY: THE PHOTOMETRIC COLOR METHOD
(IOP PUBLISHING, 2015-12)
We present a Hubble diagram of SNe II using corrected magnitudes derived only from photometry, with no input of spectral information. We use a data set from the Carnegie Supernovae Project I for which optical and near-infrared ...
Evidence for asymmetric distribution of circumstellar material around type ia supernovae.
ABSTRACT We study the properties of low–velocitymaterial in the line of sight towards nearby Type Ia Supernovae (SNe Ia) that have measured late phase nebular velocity shifts (vneb), thought to be an environment–independent ...
