How do galaxies assemble and grow their stellar mass? Answering those questions requires multiwavelength high resolution data, covering from the ultraviolet tracers of current star formation to the optical/infrared tracers of older stellar populations. This kind of data is limited to z~3 in existing HST surveys. We propose to obtain the first deep high resolution panchromatic view of galaxies at z>4 by taking deep ACS-F606W/F775W images of the very first deep public extragalactic field to be imaged by NIRcam as part of the ERS-1324 program (reaching 29AB in 7 bands from F090W to F444W). The combined dataset will be public immediately and provide the community with a sample of >100 galaxies at z<4<6 with full rest frame UV-to optical coverage. This sample will provide first answers to the following specific questions: 1) Does the spatial distribution of starforming regions and underlying quiescent stellar populations evolve in the same way? 2) Is star formation mostly in situ or merger driven? 3) Is our current measurement of the global star formation history reliable? 4) How clumpy is star formation and dust extinction at high redshift? We will make the reduced data public immediately to provide rapid understanding in the community of galaxy 17231( 4) - 26-Jul-2022 14:51:22 - [ 2] evolution in this epoch in time for JWST Cycle-2 proposals. We anticipate that the images will be used by the community for many more applications, beyond those listed above. ------------------------------------------------------------------------------------ Observations Description ------------------------ Following standar practice, each orbit will be split into two observations, collecting a total of 10/20 exposures to eliminate defects and cosmic rays. We will use a dithering pattern spaced by semi-integer pixel offsets to recover the sampling of the point spread function as well as cover the ACS gap. The observations are broken into 2-orbit visits to maximize schedulability. ------------------------------------------------------------------------------------ 17231( 4) - 26-Jul-2022 14:51:22 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 ABELL-2744-N UNIDENTIFIED, PARALLEL RA=00H13M58.2000S, J2000 V = 25 IRCAM-PARALL FIELD DEC=-30D18'55.00" EL Reference Frame: Other: Other... ------------------------------------------------------------------------------------------------------------------------------------ 17231( 4) - 26-Jul-2022 14:51:22 - [ 4] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type ACS-WFC-DITHER-BOX Pattern_Purpose DITHER Number_Of_Points 4 Point_Spacing 0.2637 Line_Spacing 0.1856 Coordinate_Frame POS-TARG Pattern_Orient 20.70 Angle_Between_Sides 69.02 Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 2 Primary_Pattern Secondary_Pattern Pattern_Type ACS-WFC-DITHER-LINE LINE Pattern_Purpose DITHER DITHER Number_Of_Points 3 2 Point_Spacing 0.2637 0.1856 Line_Spacing Coordinate_Frame POS-TARG POS-TARG Pattern_Orient 20.70 110.70 Angle_Between_Sides Center_Pattern NO NO ------------------------------------------------------------------------------------------------------------------------------------ 17231( 4) - 26-Jul-2022 14:51:22 - [ 5] Visit: 01 Visit Requirements: On Hold Comments: Additional Comments: Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 ABELL-2744- ACS/WFC ACCUM WFCENTER F606W CR-SPLIT=NO 1 1000 S PATTERN 1 1 NIRCAM-PARA see below LLEL (4710 S) ------------------------------------------------------------------------------------------------------------------------------------ Sub Exposures ------------------------------------------------------------------------------------------------------------------------------------ Target | Exp |Instr | Oper. | Aper |Spectral|Cent.|Primary |Secondary |Iteration |CR-SPLIT |Orbit |Duration Name | Num |Config | Mode | or FOV |Element |Wave.|Pattern Pos |Pattern Pos |Num |Num |Number | ------------------------------------------------------------------------------------------------------------------------------------ ABELL-2744-NIRCAM-P 1 ACS/WFC ACCUM WFCENTER F606W 1 none none none 1 1159.0 S ARALLEL ABELL-2744-NIRCAM-P 1 ACS/WFC ACCUM WFCENTER F606W 2 none none none 1 1159.0 S ARALLEL ABELL-2744-NIRCAM-P 1 ACS/WFC ACCUM WFCENTER F606W 3 none none none 2 1196.0 S ARALLEL ABELL-2744-NIRCAM-P 1 ACS/WFC ACCUM WFCENTER F606W 4 none none none 2 1196.0 S ARALLEL 17231( 4) - 26-Jul-2022 14:51:22 - [ 6] Visit: 02 Visit Requirements: SAME ORIENT AS 01 On Hold Comments: Additional Comments: Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 ABELL-2744- ACS/WFC ACCUM WFCENTER F606W CR-SPLIT=NO 1 1000 S POS TARG 0, 3;
