This is the new activation of program 10616 for a 6-orbit NICMOS observation of GRB 050904. The relevant target is (#5) GRB050904 is tied to visits 11 and 12 (3 orbits each). The setup for NICMOS is the same as in the previous observations (visit 09). The Visit Planner tool indicates that the earliest possible activation window is June 10, 2006. Please execute as soon as possible within the window (subject to additional constraints, e.g. SAA). ----- Submission 1 (Mon May 09 18:13:21 GMT 2005) ----- Phase II Proposal 10616 (cycle14-highz) successfully submitted. ----- Submission 2 (Mon May 09 20:41:48 GMT 2005) ----- Phase II Proposal 10616 (cycle14-highz) successfully submitted. ----- Submission 3 (Tue May 10 17:34:10 GMT 2005) ----- ----- Submission 4 (Tue Sep 06 21:24:36 GMT 2005) ----- ----- Submission 5 (Thu Sep 08 20:49:39 GMT 2005) ----- ----- Submission 7 (Sat Mar 25 00:27:30 GMT 2006) ----- This is a target-of-opportunity program and exact coordinates and orbit planning are not possible at the present.

Using Swift GRBs to Pinpoint the Highest Redshift Galaxies While there is convincing evidence that the Universe was re-ionized between redshifts of 6.5 and 15, the role of galaxies in this process is still not understood. Several star-forming galaxies at z~6 have been identified in recent deep, narrow-field surveys, but the expensive observations along with cosmic variance and contamination make it difficult to assess their contribution to re-ionization. Moreover, the detection of galaxies at z>7 is exceedingly difficult even with the Hubble UDF or cluster lensing. Significant progress can be made using gamma-ray bursts (GRBs) localized with the now-operational Swift satellite, which is capable of detecting bursts out to z>10. GRBs have the advantage of being an uncontaminated signpost for star-formation, and their afterglows are sufficiently bright even at z>6 to allow photometric selection (via the Ly-alpha drop out technique) with 2-5 meter telescopes. Using our approved TOO programs at an extensive range of facilities (from 1-m robotic telescopes to Keck/Magellan), we can rapidly find afterglows at z>6 and easily distinguish them from dusty low redshift bursts. This approach is highly efficient compared to current techniques, especially at z>7. Here we request imaging with NICMOS (z>6), ACS (z~6), and Spitzer/IRAC to characterize the properties (SFR, age, morphology) of up to five galaxies located in this manner, and begin to address their role in re-ionization. These observations are requested as >2 month TOOs, allowing flexibility of scheduling and at the same time taking a unique and timely advantage of the exquisite performance of three of NASA's premier missions.
Target Sample: We will trigger on long-duration gamma-ray bursts detected with the Swift satellite, or by other satellites, for which we have indication from the afterglow emission that the redshift is z>6. The purpose of the study is to image the host galaxy and therefore the observations will be delayed by several weeks (nominally t>2 months, but this will be assessed on a case-by-case basis) to ensure that the afterglow fades away below the detection level of HST. There are two cases: 1. Redshift z~6-7: We will use 2 orbits with ACS+F850LP and 4 orbits with NICMOS/NIC3+F160W. 2. Redshift z>7: We will use only NICMOS/NIC3+F160W for six orbits. The templates supplied with the phase-II are for case (1), but will be modified when targets for this program become available (along with coordinates and the requested time delay before observations are made).
