... George Benedict, University of Texas at Austin . ... Abstract . ... Quasars at Redshift z=6 and Early Star Formation History . ... The cosmic distance scale and dark energy are two key issues in modern astrophysics, and HST has played a vital role in probing both. On the one hand, HST has been involved in cosmic distance measurements since its inception, largely through the H 0 Key Project, which used WFPC2 to identify and photometer Cepheids in 31 spiral galaxies at distances from 60 to 400 Mpc. ...
