Abstract The aim of these observations is to obtain deep z/ACS and H/NICMOS images in the core of two lensing clusters, A1835 and AC114, where a few z ~ 7-10 galaxy candidates have been selected from our ultra-deep JHK imaging program with Isaac/VLT. Spectroscopic observations have allowed to confirm 2 of these candidates thanks to the detection of faint emission lines identified as Lyman alpha at z=7.2 and 10. Our HST project is focused on two main goals: (1) the morphological confirmation of galaxy candidates lying near critical lines, and (2) the determination of the physical scales involved in star-forming regions at z ~ 7-10. These goals should have important implications on our present knowledge of the galaxy formation process in the early Universe. ------------------------------------------------------------------------------------ Observations Description ------------------------ blabla Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- ------------------------------------------------------------------------------------ 10154( 7) - 09/15/04 14:06 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 A1835 CLUSTER OF GALAXIES, RA=14H01M2.7000S +/- 0.1", J2000 V = 27.0 GRAVITATIONAL LENS DEC=+02D51'40.00" +/- 0.1" Coordinate Source: GUIDE_STAR_CATALOG Comments: The center and roll angle of this observations were chose to match the area covered in JHK with the ISAAC instrument on VLT. 2 AC114 CLUSTER OF GALAXIES, RA=22H58M48.2000S +/- 0.1", J2000 V = 27.0 GRAVITATIONAL LENS DEC=-34D47'55.00" +/- 0.1" Coordinate Source: GUIDE_STAR_CATALOG Comments: The center and roll angle of this observations were chose to match the area covered in JHK with the ISAAC instrument on VLT. 3 A1835NICMOS CLUSTER OF GALAXIES, RA=14H01M0.0000S +/- 0.1", J2000 V = 27.0 GRAVITATIONAL LENS DEC=+02D52'25.00" +/- 0.1" Coordinate Source: GUIDE_STAR_CATALOG Comments: The center and roll angle of this observations were chose to match in position z>7 galaxy candidates discovered in ultra-deep JHK ground based observation. 4 AC114NICMOS CLUSTER OF GALAXIES, RA=22H58M50.0000S +/- 0.1", J2000 V = 27.0 GRAVITATIONAL LENS DEC=-34D48'34.00" +/- 0.1" Coordinate Source: GUIDE_STAR_CATALOG Comments: The center and roll angle of this observations were chose to match in position z>7 galaxy candidates discovered in ultra-deep JHK ground based observation. 10154( 7) - 09/15/04 14:06 - [ 3] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type ACS-WFC-DITHER-LINE Pattern_Purpose DITHER Number_Of_Points 3 Point_Spacing 0.17 Line_Spacing Coordinate_Frame POS-TARG Pattern_Orient 47.23 Angle_Between_Sides Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ 10154( 7) - 09/15/04 14:06 - [ 4] Visit: 01 Visit Priority: Visit Requirements: PCS MODE FINE; GUID TOL 0.05"; ORIENT 41.0D TO 49.0 D On Hold Comments: Additional Comments: Deep observation of the cluster lens AC114 in the F850LP filter covering the central part of the cluster.
