10. Closing in on the Hydrogen Reionization Edge at z < 7.2 with Deep STIS/CCD Parallels.

Abstract

We present the first results of a project with the Hubble Space Telescope to take STIS parallel spectra to constrain the onset of reionization in the IGM shortly after the first UV sources formed in the early Universe. This epoch would have left a faint but sharp spectral feature on top of the global background that marks the transition from a neutral to a fully ionized IGM at a predicted redshift $z_{ion} \simeq 5-10$ (Baltz et al. 1998). We found a faint but significant spectral emission band at 8457 Å on top of the Zodiacal foreground, which we identify with a weak atmospheric O-I line that entered some of the parallels (despite the use of mostly orbital dark time), rather than coming from the reionization feature. We use this to set tentative limits to the real Hydrogen edge signal of $\le 2\times 10^{-21}$ erg/cm2/s/Hz/sr at $z_{ion} \ge 6.0$. [ABSTRACT FROM AUTHOR]
