PI: Dr. James C. Green University of Colorado at Boulder CoI: Dr. Cynthia Froning University of Colorado at Boulder N CoI: Prof. J. Michael Shull University of Colorado at Boulder Y ------------------------------------------------------------------------------------ Abstract Intergalactic Ly-alpha opacity suggests that H I was reionized at z ~ 6, while He II reionization was delayed to z ~ 3. Both epochs are slightly in disagreement with recent (WMAP-3) inferences from the CMB optical depth, which suggest that IGM reionization occurred at z = 10.7 (+2.7, -2.3) (Spergel et al. 2007). However, these two methods are sensitive to different ranges of ionization (neutral fractions), which allows a partially ionized IGM between z = 6-10 produced by early stars and black holes. One of the major contributions of FUSE to cosmological studies was the detection of He II Ly-alpha (Gunn-Peterson) absorption in the spectra of two AGN at redshifts z = 2.72-2.89. The He II absorption is quite patchy between redshifts z = 2.6 and 3.2 probably because the IGM is clumpy and the reionization process is affected by source fluctuations, spectra, and radiative transfer through the IGM. Observations of the He II absorption can therefore be used as diagnostics of the ionizing sources and radiative transport over large (30-50 Mpc) distances through the IGM. The ionizing radiation field appears to be softer (higher He II/H I) in the galaxy voids. These void regions may be ionized by local soft sources (dwarf starburst galaxies), or the QSO radiation may softened by escape from AGN cores and transport through denser regions in the cosmic web.With COS, we will observe the brightest He II target, HE2347-4342, a QSO with z_em = 2.885. Our goal is to obtain a G130M moderate-resolution (R = 20, 000) spectrum from 1145-1450A. Because COS has far greater throughput than either STIS or FUSE, we will be able to resolve and characterize the He II absorption lines. The region shortward of the redshifted He II (Ly-alpha) corresponds to z = 2.77-2.92, where He II exhibits patchy transmission and absorption. The ratio of He II/H I (Ly-alpha line) opacities will provide information on the ionizing radiation field (and ionizing sources) at 1 and 4 ryd. We will perform similar He II studies on three other targets, HS1700+6416, PKS1935-692, and Q0302-003. ------------------------------------------------------------------------------------ Observations Description ------------------------ Two 5-orbit G130M visits, and one 4-orbit G140L visit. WFC3 parallels attached to all orbits. We use 2.5 times the nominal flux for safety and buffer-time calculations, but 0.5 times the nominal flux to determine TA exposure times. 11528( 10) - 18-May-2011 18:16:49 - [ 2] Only one target will be observed in Cycle 17. Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- Roll contraint added to prevent WFC3 from imaging a bright star.
