SNIa Environments: Unusually Luminous%3F
Graham, Pritchet

We investigate the question: are more SNIa from more number-, dense and-or luminous environments, or in other words, are there disproportionally, more SNIa events in galaxies in clusters%3F Using Gwyn's (2005) stacked, images and photometric redshifts, we compare the number-densities and, galaxy brightnesses at SNIa positions to random coordinates.
