Title: $HST spectroscopy of Q0302-003
Abstract: The Goddard High Resolution Spectrograph (GHRS) has obtained spectra of QSO 0302-003 in an effort to detect and measure He II Lyα absorption from the diffuse intergalactic medium and/or discrete clouds. The strong observed absorption—even in the "Dobrzycki-Bechtold void"—suggests that at least some of it originates in the diffuse gas. Future observations with the newly installed Space Telescope Imaging Spectrograph (STIS) on HST, and possibly with the Cosmic Origins Spectrograph (COS), an instrument recently proposed to NASA for installation on HST in 2002, should separate decisively the cloud and inter-cloud contributions.
