This motivates the study of cluster galaxies at redshifts > 1.5, where most of the stars in cluster galaxies form, and the clusters assemble. Here we propose a detailed study of galaxy evolution in one galaxy cluster at z=1.62 using HST/ACS and WFC3 imagining, and WFC3 spectroscopy. This galaxy cluster was identified solely as an overdensity of Spitzer/IRAC sources with red IRAC colors, with little bias toward optically red or blue galaxies. The cluster has only 12 spectroscopic redshifts, mostly for active and star-forming galaxies, and measuring redshifts for most of the passive galaxies is beyond the capabilities of ground-based telescopes. The scientific goals of this proposal are (1) to measure spectroscopic redshifts of the red, passive galaxies to J(AB)=22.8 mag (~J* + 1 mag) in this cluster with the WFC3 grism in order to confirm cluster members and map the cluster in redshift space, (2) to measure the strength of the 4000 Angstrom/Balmer break from the grism spectra, providing valuable information on the galaxy stellar population ages and masses, (3) to measure the spatially resolved structures and faint, H(AB)=26 mag, subcomponents in these galaxies, constraining their assembly and formation histories, and (4) to 12590( 15) - 12-Oct-2011 15:39:42 - [ 2] use these observations to make comparisons to expectations from theoretical galaxy formation models. ------------------------------------------------------------------------------------ Observations Description ------------------------ Observing Description for HST Cycle 19 Proposal 12590 PI: Casey Papovich (papovich@physics.tamu.edu) We will observe the galaxy cluster IRC 0218A at z=1.6 with -10 orbits of WFC3 G102 grism spectroscopy - 1 orbit of WFC3 F105W imaging - 2/3 orbit of WFC3 F125W imaging - 4/3 orbit of WFC3 F160W imaging - 2 orbits of ACS WFC F475W imaging - 2 orbits of ACS WFC F814W imaging. ** WFC3 G102 Grism observations: (Visits 1-5) While working on the Phase II with our Technical Contact, we discovered that there are no pointings with 2 suitable guide stars for optimal field pointing. For any combination of 2 guide stars, the cluster galaxies fall near the edge of the WFC3 FOV, and the allowable ORIENT angles cause the light dispersed by the grism to fall off the chip. After much trial and error, we adopted a strategy using only a single guide star. We therefore have broken the 10 grism orbits into 5 separate visits of 2 orbits each. Also, because we are aware that some rotation is expected during an orbit using only 1 guide star, we are adopting the following strategy during each 2 orbit visit: Orbit 1: direct (A) - grism (A) - grism (B) - direct (B) Orbit 2: direct (C) - grism (C) - grism (D) -direct (D) where ABCD are four different 1/2-integer pixel positions. We adopt the same dither positions as the standard WFC3-IR-DITHER-BOX pattern, but give the offsets explicitly so that we can effectively spread the dithers over two orbits. By placing a direct image at the beginning and end of each orbit we can track any rotation. We have constrained Visit 1 (the first grism visit) to occur well in advance of Visits 2-5 (the other grism visits) so that we can verify that this plan produces good data before committing to Visits 2-5. Using 1 guide star allows for a large range of ORIENT, and we constrain Visits 1-5 to each be separated by 10 deg in ORIENT. This will mitigate any collisions between spectra traces. ** WFC3 Imaging: (Visits 6, 9) 12590( 15) - 12-Oct-2011 15:39:42 - [ 3] The F105W imaging is offset slightly from the cluster center coordinates. This is to include as many cluster members as possible. To include as many cluster members as possible, we have added an ORIENT constraint designed for optical field coverage (this includes a small associated group of galaxies to the NE of the cluster core). For the F125W and F160W imaging, we have centered the field to minimze the overlap with existing WFC3 imaging from the CANDELS observations in this field. (CANDELS imaged with F125W and F160W and we avoid duplication.) There is a small overlap to include imaging of a cluster member that falls on the "death star" of the CANDELS WFC3 imaging. We have added an ORIENT constraint to minimze overlap with the existing CANDELS imaging. The constraint is ORIENT=40-50 deg. The DITHER pattern we have adopted for the WFC3 F125W and F160W imaging is identical to that of CANDELS. CANDELS was constrained by the need for 1/2-integer pixel shifts in the primary WFC3 images and ACS parallels. While we have no ACS constraint (no parallels) we adopt the same dither pattern to allow for uniform F125W and F160W mosaic with CANDELS with a very similar PSF, etc. For the F105W imaging, we adopt the standard WFC3-IR-DITHER-BOX. We have checked that temporal variations in the sky background have a negligible impact on object S/N for our different observing windows. Therefore, we have no constrain owing to changes in background. ** ACS Imaging: (Visits 7, 8) For the F475W and F814W images, we adopt a dither pattern to fill in the chip gap and include fraction pixel shifts. This uses the 2 pt DITHER-LINE pattern as the primary (to fill in the chip gap) and the DITHER-BOX as a subpattern, to take 4 pt dither at each position of the DITHER-LINE pattern. Because we take 2 x 4 ACS exposures we are not using CRSPLIT (=no). We have manually entered the "ACTUAL-DURATION" to each ACS exposure to fill in the visibility window for the orbit. (If the actual duration of the visibility window changes, we will manually change the ACTUAL DURACTIONS". To maximize the field overlap we have included a constraint that both images be taken with the same ORIENT, though the actual ORIENT is not constained. The ACS imaging is centered at a point to maximize overlap with the WFC3 imaging (both from here and the CANDELS data). ------------------------------------------------------------ Real Time Justification ----------------------- Calibration Justification ------------------------- 12590( 15) - 12-Oct-2011 15:39:42 - [ 4] Additional Comments ------------------- ------------------------------------------------------------------------------------ 12590( 15) - 12-Oct-2011 15:39:42 - [ 5] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 IRC0218A-CEN CLUSTER OF GALAXIES, RA=02H18M19.7500S +/- 0.1", J2000 V = 24 Redshift z=1.62, J(AB)=21-26 TER-G102 HIGH REDSHIFT CLUSTER DEC=-05D10'15.00" +/- 0.1" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 4 IRC0218A-ACS CLUSTER OF GALAXIES, RA=02H18M19.7500S +/- 0.1", J2000 V = 24 Redshift z=1.62, J(AB)=21-26 HIGH REDSHIFT CLUSTER DEC=-05D09'28.00" +/- 0.1" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 3 IRC0218A-F10 CLUSTER OF GALAXIES, RA=02H18M18.5000S +/- 0.1", J2000 V = 24 Redshift z=1.62, J(AB)=21-26 5W HIGH REDSHIFT CLUSTER DEC=-05D10'19.00" +/- 0.1" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 2 IRC0218A-WFC CLUSTER OF GALAXIES, RA=02H18M25.5000S +/- 0.1", J2000 V = 24 Redshift z=1.62, J(AB)=21-26 3-OFFSET HIGH REDSHIFT CLUSTER DEC=-05D10'8.00" +/- 0.1" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 12590( 15) - 12-Oct-2011 15:39:42 - [ 6] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-IR-DITHER-BOX-MIN Pattern_Purpose DITHER Number_Of_Points 4 Point_Spacing 0.572 Line_Spacing 0.365 Coordinate_Frame POS-TARG Pattern_Orient 18.528 Angle_Between_Sides 74.653 Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 4 Primary_Pattern Secondary_Pattern Pattern_Type ACS-WFC-DITHER-LINE ACS-WFC-DITHER-BOX Pattern_Purpose DITHER DITHER Number_Of_Points 2 4 Point_Spacing 3.011 0.265 Line_Spacing 0.187 Coordinate_Frame POS-TARG POS-TARG Pattern_Orient 85.28 20.67 Angle_Between_Sides 69.05 Center_Pattern NO NO ------------------------------------------------------------------------------------------------------------------------------------ 12590( 15) - 12-Oct-2011 15:39:42 - [ 7] Visit: 01 Visit Requirements: ORIENT 49D TO 50 D; ORIENT 0.0D TO 0.0 D On Hold Comments: Additional Comments: We were unable to achieve two suitable guide stars for high-priority galaxies, such that they would lie on the WFC3 detector and have the light dispersed from the grism falling on the detector.
