----- Attempting Submission 3 (Thu Nov 14 16:25:57 GMT 2019) -----Focusing The Next Generation of Extraordinary Cluster Lenses for JWSTWe propose to observe 3 new extraordinary lensing clusters showing extensive strong lensing evidence. These clusters are massive (M_500c > 6.0 x 10e14Msol) and reveal a large lensing cross-section, having an Einstein radii of 46'', 49'', 52'' and showing multiple concentric arcs. Our proposed use of HST data will allow us to suitably map the dark matter and build a reliable strong lensing model due to their apparently smooth mass distribution (as opposed to most of HFF clusters) and significant number of lensing constraints. In addition, giant arcs (e.g. 21'' in extent, and some very bright) promise significant science impact once the lensing model has been ''focused''. By observing those targets we will calibrate new cosmic telescopes for JWST. In our proposed observations, we lay the groundwork for the best outcome possible by targeting obviously spectacular lensing cluster promoting high-redshift studies of the magnified background universe with JWST.To be Reviewed:
We request to observe each cluster with four filters, using in 3 orbits of HST time: one
orbit each with the ACS/F606W filter, one orbit with the ACS/F814W filter, and one orbit
with WFC3/IR split between two filters, F105W and F140W. This brings the total request
to 9 orbits.
Using the ETC, we
conservatively estimate a 5 point source detection of 27.1 mag in F606W, 26.5 mag in
F814W, and 26 mag in each of the IR filters
The exact magnitudes depend on the actual
visibility time and source spectral energy distribution; For our targets, the APT estimates
53-54 minutes per orbit, and we made these estimates for a flat spectrum.
3 filters, requiring
at least 4 images (dithers) per filter (for good PSF reconstruction)Dr. Mahler is an expert in strong lensing with ample experience in modeling the HFF clusters (Mahler et al. 2018) is part of the LENSTOOL development team, and is an expert in MUSE IFU spectroscopy analysis.
