Abstract:
We conduct precise strong lensing mass modeling of four Hubble Frontier
Field (HFF) clusters, Abell 2744, MACS J0416.1-2403, MACS J0717.5+3745,
and MACS J1149.6+2223, for which HFF imaging observations are completed.
We construct a refined sample of more than 100 multiple images for
each cluster by taking advantage of the full-depth HFF images, and
conduct mass modeling using the glafic software, which assumes simply
parametrized mass distributions. Our mass modeling also exploits a
magnification constraint from the lensed SN Ia HFF14Tom for Abell 2744
and positional constraints from the multiple images S1-S4 of the
lensed supernova SN Refsdal for MACS J1149.6+2223. We find that our
best-fitting mass models reproduce the observed image positions with
rms errors of ∼0.4", which are smaller than rms errors in previous
mass modeling that adopted similar numbers of multiple images. Our
model predicts a new image of SN Refsdal with a relative time delay
and magnification that are fully consistent with a recent detection of
reappearance. We then construct catalogs of z∼6-9 dropout galaxies
behind the four clusters and estimate magnification factors for these
dropout galaxies with our best-fitting mass models. The dropout sample
from the four cluster fields contains ∼120 galaxies at z≳6, about
20 of which are predicted to be magnified by a factor of more than 10.
Some of the high-redshift galaxies detected in the HFF have
lensing-corrected magnitudes of MUV~-15 to -14. Our analysis
demonstrates that the HFF data indeed offer an ideal opportunity to
study faint high-redshift galaxies. All lensing maps produced from our
mass modeling will be made available on the Space Telescope Science
Institute website (https://archive.stsci.edu/prepds/frontier/lensmodels/).
Description:
We use the public HFF data
(http://www.stsci.edu/hst/campaigns/frontier-fields/) for our
analysis. The HFF targets six massive clusters, Abell 2744 (z=0.308),
MACS J0416.1-2403 (z=0.397), MACS J0717.5+3745 (z=0.545), MACS J1149.6+2223
(z=0.541), Abell S1063 (z=0.348), and Abell 370 (z=0.375), which have
been chosen according to their lensing strength and also their
accessibility from major ground-based telescopes. The cluster core and
parallel field region of each cluster are observed deeply with the IR
channel of Wide Field Camera 3 (WFC3/IR) and the Advanced Camera for
Surveys (ACS). As of 2015 October, HST observations for the first four
clusters, Abell 2744, MACS J0416.1-2403, MACS J0717.5+3745, and
MACS J1149.6+2223, are completed.
In this study, we use the Version 1.0 data products of drizzled images
with a pixel scale of 0.03"/pixel provided by the Space Telescope Science
Institute (STScI). The images for each cluster consist of F435W (B435),
F606W (V606), and F814W (i814) images from ACS, and F105W (Y105),
F125W (J125), F140W (JH140), and F160W (H160) images from WFC3/IR.
