Abstract Our goal is to elucidate the role of QSOs and galaxies at the tail end of reionization by identifying z~6 galaxies near SDSS z>6 QSOs through their red i-z colors. A similar technique was used by the SDSS to identify the QSOs themselves. Based on our understanding of the growth of structure in the Universe and on observations at z ~= 4, we expect z~6 QSOs to be associated to the high peaks in the matter density distribution. Therefore, they should be surrounded by an excess of objects - as compared to random fields - unless the ionizing radiation from the QSOs themselves is inhibiting star formation. We will concentrate on 5 QSOs discovered by the SDSS at z>~6 and spend 7 orbits with ACS on each of the QSO fields (2.5 in F775W - i - and 4.5 in F850LP - z), for a total of 35 orbits. The exposures are optimized for the detection of objects with i-z> 2. The reference properties of the field population will be provided by GOODS which is reaching the same depth. The proposed observations will be capable of revealing the dominant effect between galaxy suppression by the QSO ionizing flux and number density excess due to clustering. We will test whether the balance between suppression and enhancement evolves with redshift. We will also be able to estimate for these fields the ionizing continuum contribution by galaxies and compare it with that of the QSOs. If galaxies are found to be comparably important to QSOs in these selected fields, the idea that hydrogen reionization is primarily due to stellar radiation would be significantly strengthened. ------------------------------------------------------------------------------------ 9777( 3) - 05/02/03 17:39 - [ 2] Observations Description ------------------------ For each target we plan to obtain a 2.5 orbits image (10 * 600 s) in F775W and a 4.5 orbit image (9 * 1200 s) in F850LP so as to reach a depth comparable to that of the GOODS survey. Two of the targets are located near a bright star. We plan to place the bright star in the gap between the two CCDs so as to avoid blooming of the exposures. The orientation has to be selected among a number of allowed ranges so as to avoid spiders from overlapping the target QSO. For the remaining three targets no particular precaution is needed. The observations will adopt a 3-4-3 dither pattern in F775W and a 3-3-3 pattern in F850LP. There will be no attempt to cover the gap between the two CCDs.

By centering the object on WFC1 and using orient constraints we keep the side effects to a minimum. 9777( 3) - 05/02/03 17:39 - [ 4] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type ACS-WFC-DITHER-BOX Pattern_Purpose DITHER Number_Of_Points 4 Point_Spacing 0.265 Coordinate_Frame POS-TARG Pattern_Orient 20.67 Center_Pattern YES ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 2 Primary_Pattern Secondary_Pattern Pattern_Type LINE Pattern_Purpose DITHER Number_Of_Points 3 Point_Spacing 0.165 Coordinate_Frame POS-TARG Pattern_Orient 45.0 Center_Pattern YES ------------------------------------------------------------------------------------------------------------------------------------ 9777( 3) -
