Host Galaxy Extinction of SNIa: Co-evolution of ISM Structure and Extinction Law with Star-Formation

Abstract

This paper presents a mechanism that may modify the extinction law for SNIa observed at higher redshift. Starting from the observations that (1) SNIa occur predominantly in spiral galaxies, (2) star-formation ejects ISM out of the plane of spirals, (3) star-formation alters the extinction properties of the dust in the ISM, and (4) there is substantially… (More)
