Title: Spectroscopic Parallax for Cepheids/SN Ia hosts from Pan-STARRS

Abstract: This proposal combines two science programs that each require multi- object, medium-resolution spectroscopy. The first of these programs will enable a more precise determination of the Hubble constant by measuring the spectroscopic parallax of stars in Cepheid fields. The second will measure the redshifts of Type Ia supernovae discovered by Pan-STARRS, by observing their host galaxies, so that they can be used to determine cosmological parameters.

Program Type: ITAC
