Finally completed a project I had in the back of my head ever since I heard of the SDSS-II Supernova program. The idea was: can you use the inferred extinction (AV) from SNIa lightcurve fits to probe the dusty ISM of the host galaxies. It is tied to the prior for the AV in those lightcurve fit.
I explored how the AV distribution depends on host galaxy properties and one thing pops out immediately: the host galaxy disk's inclination is IMPORTANT! Other properties not as much.
Well the paper is done. Off the MNRAS. Hope my point is helpful for future supernova work.
In other news: Lorentz Center SED workshop is taking off. hurray!
