Abstract:
We report the spectroscopic confirmation of 22 new multiply lensed
sources behind the Hubble Frontier Field (HFF) galaxy cluster MACS
J0416.1-2403 (MACS 0416), using archival data from the Multi Unit
Spectroscopic Explorer (MUSE) on the VLT. Combining with previous
spectroscopic measurements of 15 other multiply imaged sources, we
obtain a sample of 102 secure multiple images with measured redshifts,
the largest to date in a single strong lensing system. The newly
confirmed sources are largely low-luminosity Lymanα-emitters
with redshift in the range [3.08-6.15].With such a large number of
secure constraints, and a significantly improved sample of galaxy
members in the cluster core, we have improved our previous strong
lensing model and obtained a robust determination of the projected
total mass distribution of MACS 0416. We find evidence of three cored
dark-matter halos, adding to the known complexity of this merging
system. The total mass density profile, as well as the sub-halo
population, are found in good agreement with previous works. We update
and make public the redshift catalog of MACS 0416 from our previous
spectroscopic campaign with the new MUSE redshifts. We also release
lensing maps (convergence, shear, magnification) in the standard HFF
format.
Description:
We used archival MUSE (Bacon et al., 2012, The Messenger, 147, 4) data
from two different programs which covered the North-East (NE) and
South- West (SW) regions of MACS 0416.
