Abstract:
We measure the size-mass relation and its evolution between redshifts
1<z<3, using galaxies lensed by six foreground Hubble Frontier Fields
clusters. The power afforded by strong gravitation lensing allows us
to observe galaxies with higher angular resolution beyond current
facilities. We select a stellar mass limited sample and divide them
into star-forming or quiescent classes based on their rest-frame UVJ
colours from the ASTRODEEP catalogues. Source reconstruction is
carried out with the recently released lenstruction software, which is
built on the multipurpose gravitational lensing software lenstronomy.
We derive the empirical relation between size and mass for the
late-type galaxies with M*>3x109 M☉ at 1<z<2.5 and
M*>5x109M☉ at 2.5<z<3, and at a fixed stellar mass, we find
galaxy sizes evolve as Reff∝(1+z)-1.05±0.37. The
intrinsic scatter is <0.1dex at z<1.5 but increases to ∼0.3dex at
higher redshift. The results are in good agreement with those obtained
in blank fields. We evaluate the uncertainties associated with the
choice of lens model by comparing size measurements using five
different and publicly available models, finding the choice of lens
model leads to a 3.7 per cent uncertainty of the median value, and ∼25
per cent scatter for individual galaxies. Our work demonstrates the
use of strong lensing magnification to boost resolution does not
introduce significant uncertainties in this kind of work, and paves
the way for wholesale applications of the sophisticated lens
reconstruction technique to higher redshifts and larger samples.
Description:
We base our analysis on the v1.0 reductions of HFF imaging data and
the latest publicly available lens models
(http://www.stsci.edu/hst/campaigns/frontier-fields/Lensing-Models).
The HFF program provides ultradeep observations over six lensing
clusters, Abell 2744, MACS J0416.1-2403, MACS J0717.5+3745, MACS
J1149.5+2223, Abell S1063 and Abell 370, and obtains images in HST ACS
(F435W, F606W, F814W) and WFC3/IR (F105W, F125W, F140W, F160W) on both
the main cluster and the parallel fields. We adopt the multiwavelength
photometric catalogues of these images from the ASTRODEEP project
(http://www.astrodeep.eu/), which collects imaging from HST to
ground-based K-band and Spitzer/IRAC, and provides photometrically
derived global galaxy properties (e.g. redshift, stellar mass, star
formation rate) from several studies derived with SED-fitting codes
