dust extinction and reddening

I worked out the details (on paper) of two projects we are thinking about relating to dust attenuation. In the first, we look at stellar spectra in the SDSS as a function of Galactic reddening and determine the dust attenuation law at high resolution. In the second, we look at quasar photometry in the ultraviolet as a function of line-of-sight separation from galaxies of differing properties to get the dust–galaxy cross-correlation function.
