Abstract:
Jakobsen et al 1994 have claimed the first detection of Gunn-
Peterson absorption by He II in the diffuse intergalactic
medium (IGM). Although likely, they are not certain that the
absorption is from the IGM, and they are unsure how much of
the absorption is due to He II in individual LymanAlpha
clouds which are completely unresolved in their objective
prism spectrum with 25 Angstrom resolution.
We will obtain spectra of one QSOs with three goals.
(1) The spectrum of the QSO will have SNR=10 per 0.57Angstrom,
which is enough that we can separate out absorption due to He
II in LyAlpha forest lines and diffuse IGM absorption. We
should be able to measure Tau _GP, which gives part of the
spectrum of the ionizing radiation. (2) We will have the
spectral resolution and SNR to see that the GP absorption does
not begin for some distance away from the QSO, because it
is surrounded by a Stromgren sphere of high ionization.
The extent of this sphere depends on the intensity and shape
of the spectra of ionizing radiation, both from the QSOs and
in the IGM in general. (3) If the sources of energy
for the re-ionization of the IGM were relatively scarce (major
explosions, QSOs) the IGM will not all be of the same
ionization, and we should see less GP absorption in some
places in the spectrum.

Observing_Description:
We will observe the QSO 1935-69 for the full 16 orbits
allocated to us. We will use the HRS in ACCUM mode with
the G140L grating. We are using FOS for the ACQ because
the object is so faint.
