Abstract:
Cluster lensing has become an important tool in the search for
high-redshift galaxies through its ability to magnify sources. In
order to determine the intrinsic properties of these galaxies, lensing
mass models must be constructed to determine the magnification of the
images. These models are traditionally 2D, focusing on the mass within
the cluster and either ignoring or approximating any contribution from
line-of-sight galaxies. In this paper, we present the first full set
of 3D mass models of the six Hubble Frontier Fields and use them to
test for systematic biases in magnifications due to using the
traditional 2D approach. We find that omitting foreground or
background galaxies causes image position offsets between 0.1 and
0.4arcsec, a non-negligible fraction of the typical 0.3-0.7arcsec
residuals of current state-of-the-art models. We also find that median
image magnifications can shift by up to 6 per cent, though it is
dependent on the field. This can be alleviated in some cases by
approximating the mass in the lensing plane, but a 5 per cent
magnification bias still exists in other cases; image position offsets
are also improved, but are still present at 0.10arcsec.
Description:
The Hubble Frontier Fields (HFF) programme (Lotz et al.
2017ApJ...837...97L 2017ApJ...837...97L) has provided a wealth of data for the lensing and
greater astrophysics communities. In this paper, we have used these
data in order to conduct the first comprehensive study of
magnification biases due to LOS galaxies in cluster lensing. In order
to do this, we have created the first set of 3D mass models of all six
Frontier Fields, in addition to two single-plane models.
In order to determine the effects of LOS galaxies, we created a mock
multiplane model for each field and fit it with two single-plane
models, either with or without LOS galaxies scaled to the lens plane,
and a multiplane model. These models were created with the same
inputs, i.e. same number of haloes and cluster members, and were
optimized to fit the 3D data in the same way. This allowed us to
quantify any bias that would be introduced from modelling a multiplane
system using only single-plane models.

1- 5 A5 --- ID Lens image ID
7 A1 --- f_ID [ab] Flag on ID (1)
9- 18 F10.6 deg RAdeg Right ascension (J2000) (2)
20- 29 F10.6 deg DEdeg Declination (J2000) (2)
31- 35 F5.3 --- z ? Spectroscopic redshift
37- 42 A6 --- Rank Lensed image rank (gold or bronze)
44 A1 --- f_Rank [abc] Flag on Rank (3)
46- 54 A9 --- r_z Reference for z (4)
--------------------------------------------------------------------------------
Note (1): Flag as follows:
a = This system is to be read as 'system.image.knot'. For 1.1.1 and 1.2.1,
we use the coordinates referenced in Diego et al. (2016MNRAS.459.3447D 2016MNRAS.459.3447D),
while 1.1.2 and 1.2.2 reference those in Caminha et al.
(2016A&A...587A..80C 2016A&A...587A..80C)
b = This image was proposed in Monna et al. (2014MNRAS.438.1417M 2014MNRAS.438.1417M); here we
assign it the ID 12.5
Note (2): For systems 44 and under, we use Diego et al. (2016MNRAS.459.3447D 2016MNRAS.459.3447D)
as the coordinate reference. The systems with IDs greater than that
use Karman et al. (2017A&A...599A..28K 2017A&A...599A..28K) for the coordinate reference
Note (3): Flag as follows:
a = This image was ranked gold, but we could find no data for a
spectroscopic redshift
b = This image was ranked gold, though no spectroscopic redshifts exist;
all modellers felt confident that it was part of the lensed system
c = This image was not reported to have a spectroscopic redshift in
Karman et al. (2017A&A...599A..28K 2017A&A...599A..28K), but a new reduction of the MUSE
data by B. Clement detected Lyα (private communication)

redshift

Note (G1): A flag of -1 in the redshift column denotes that it is a cluster
member that was photometrically selected
