PI: Prof. Jeff Cooke Swinburne University of Technology Y CoI: Dr. John M. O'Meara Saint Michaels College N CoI: Dr. Marc Rafelski Space Telescope Science Institute N CoI: Dr. Emma Ryan-Weber Swinburne University of Technology N CoI: Dr. Lee Spitler Macquarie University N CoI: Dr. Ikuru Iwata National Astronomical Obs of Japan (NAOJ), N Subaru Telescope CoI: Dr. Ivo Labbe Universiteit Leiden N CoI: Mr. Uros Mestric Swinburne University of Technology N ------------------------------------------------------------------------------------ Abstract We propose WFC3 imaging to map the origin and extent of escaping ionizing (< 912 A) flux for ~50 z ~ 3-4 Lyman continuum galaxies (LCGs) in the COSMOS field. LCGs are a recently identified population of galaxies selected via 30-band photometry and deep spectroscopy that exhibit excess Lyman continuum (LyC; < 912 A) flux. In this program, we will observe 2 WFC3 pointings to gather a statistical sample of the the full population. The data will (1) map the full LyC flux extent and origin, (2) measure the LyC flux as a function of galaxy luminosity, morphology, UV continuum slope, and Lya emission for the spectroscopic subset, and (3) secure the number density of this newly identified population of galaxies. This is the first systematic investigation of a z = 3-4 galaxy population analog to z > 6 galaxies responsible for cosmic reionization. LCG ionizing flux measurements will be used with our Keck/MOSFIRE restframe optical spectroscopic program to calibrate models that predict the escaping ionizing photon fraction based on nebular emission line strength ratios. The method will be used to infer galaxy ionizing photon escape fractions near, and beyond, the epoch of reionization using JWST, as direct measurements of < 912A photons at z > 5 are impossible as a result of IGM absorption. Complete LyC flux measurements, including the full extent and physical origin of the ionizing flux for proper calibration of the models at z ~ 3-4 can only be done with HST imaging. ------------------------------------------------------------------------------------ Observations Description ------------------------ This program consists of two primary and parallel fields in the COSMOS footprint. Each field has15 orbits split into three 5-orbit visits. The prime observations image with WFC3/UVIS and the F336W filter and the parallel observations image with ACS/WFC and the F435W filter. The orients are constrained in order to accommodate the targets in the primary WFC3 fields. As described in the Phase I, the WFC3/UVIS charge transfer efficiency (CTE) is degrading with time, and therefore observations need to be acquired as soon as possible. There is a relatively bright star (U ~ 15.5 and V ~ 14.1) just off 15100( 9) - 28-Feb-2018 19:52:00 - [ 2] detector chip 2 (quadrant C). However, previous observations with bright stars at that location did not result in significant "dragon's breath" flux. Prime imaging - WFC3 F336W: Exposures are post-flashed by 4e- to help mitigate the CTE observed with WFC3/UVIS. Such long exposures achieve >12e- per pixel. The 15 orbits for F336W imaging are broken into three visits of five orbits. One exposure per orbit increases the background flux to reduce the required post-flash and to maximize the total depth, as compared to half-orbit exposures (by ~0.5 mag). A minimum of eight exposures (8 orbits) is necessary to properly clean the full orbit exposures of cosmic rays. In addition, five orbits per visit result in much better alignment of objects in the UV images and cosmic ray rejection. The dither pattern per visit is set 5 times larger than the default box pattern to help minimize the blotchy pattern observed in F336W imaging (i.e., similar to that seen in Rafelski et al. 2015, AJ, 150 31, Figure 15). Reducing CTE effects and blotchy patterns are important for our science targeting extremely faint, potentially diffuse fux from high redshift galaxies. Each visit adopts a 3pt dither line pointing using pos-targs to fill in chip gaps for WFC3 and the parallel ACS observations. Parallel imaging - ACS F435W: The parallel imaging complements the F336W observations by targeting z ~ 4 galaxies. The 15 orbits will have three visits per target, with two exposures per orbit. The F435W background is sufficient that no post-flash is necessary. The dither patterns chosen will accommodate the ACS chip gap as described above. ------------------------------------------------------------------------------------ 15100( 9) - 28-Feb-2018 19:52:00 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 ZF-LCG-F1 GALAXY, HIGH REDSHIFT RA=10H00M48.5000S, J2000 V = 25.0 +/- 1.0 GALAXY DEC=+02D18'28.00" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 6 ZF-LCG-F1B GALAXY, HIGH REDSHIFT RA=10H00M48.5800S, J2000 V = 25.0 +/- 1.0 GALAXY DEC=+02D18'40.13" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 2 ZF-LCG-F2 GALAXY, HIGH REDSHIFT RA=10H00M25.6000S, J2000 V = 25.0 +/- 1.0 GALAXY DEC=+02D15'45.00" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 15100( 9) - 28-Feb-2018 19:52:00 - [ 4] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-UVIS-DITHER-BOX Pattern_Purpose DITHER Number_Of_Points 4 Point_Spacing 0.865 Line_Spacing 0.56 Coordinate_Frame POS-TARG Pattern_Orient 23.884 Angle_Between_Sides 81.785 Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ 15100( 9) - 28-Feb-2018 19:52:00 - [ 5] Visit: 01 (COSMOS_LCG1_F336W_1) Visit Requirements: SCHED 100%;
