Abstract:
We present a new lens model for the z=0.396 galaxy cluster MACS
J0416.1-2403 based on a previously known set of 77 spectroscopically
confirmed, multiply imaged galaxies plus an additional set of 42
candidate multiply imaged galaxies from past HST and new JWST data.
The new galaxies lack spectroscopic redshifts but have geometric
and/or photometric redshift estimates that are presented here. The new
model predicts magnifications and time delays for all multiple images.
The full set of constraints totals 343, constituting the largest
sample of multiple images lensed by a single cluster to date.
Caustic-crossing galaxies lensed by this cluster are especially
interesting. Some of these galaxies show transient events, most of
which are interpreted as micro-lensing of stars at cosmological
distances. These caustic-crossing arcs are expected to show similar
events in future, deeper JWST observations. We provide time delay and
magnification models for all these arcs. The time delays and the
magnifications for different arcs are generally anti-correlated. In
the major sub-halos of the cluster, the dark-matter mass from our lens
model correlates well with the observed number of globular clusters,
as expected from N-body simulations. This confirms earlier results,
derived at lower redshifts, which suggest that globular clusters can
be used as powerful mass proxies for the halo masses when lensing
constraints are scarce or not available.
Description:
MACS0416 was observed in three different epochs by JWST during October
2022 and February 2023 as part of the PEARLS program. Observations
were done in 8 filters, F090W, F115W, F150W, F200W, F277W, F356W,
F410M, and F444W.
Existing strong-lensing constraints comprise 77 multiply lensed
galaxies that produce 223 individual images. Diego et al.
(2024A&A...681A.124D 2024A&A...681A.124D, Cat. J/A+A/681/A124) (their Table A.1) gave a
complete list compiled from the literature (Jauzac et al.

2023A&A...674A..79B 2023A&A...674A..79B, Cat. J/A+A/674/A79). All galaxies in that list
have spectroscopic redshifts. Additional lensed system candidates that
lack spectroscopic redshift were identified in HST images in the
references above. This set is enlarged with more system candidates
identified with the new JWST data. We refer to this second set of
constraints as the non-spectroscopic sample. All available lensing
constraints are listed in Table B.1.
