Abstract:
We reliably extend the stellar mass-size relation over 0.2≤z≤2
to low stellar mass galaxies by combining the depth of Hubble Frontier
Fields (HFF) with the large volume covered by CANDELS. Galaxies are
simultaneously modelled in multiple bands using the tools developed by
the MegaMorph project, allowing robust size (i.e., half-light radius)
estimates even for small, faint, and high redshift galaxies. We show
that above 107M☉, star-forming galaxies are well represented
by a single power law on the mass-size plane over our entire
redshift range. Conversely, the stellar mass - size relation is
steep for quiescent galaxies with stellar masses ≥1010.3M☉
and flattens at lower masses, regardless of whether quiescence is
selected based on star-formation activity, rest-frame colours, or
structural characteristics. This flattening occurs at sizes of ∼1kpc
at z≤1. As a result, a double power law is preferred for the stellar
mass-size relation of quiescent galaxies, at least above
107M☉. We find no strong redshift dependence in the slope of
the relation of star-forming galaxies as well as of high mass
quiescent galaxies. We also show that star-forming galaxies with
stellar masses ≥109.5M☉ and quiescent galaxies with stellar
masses≥1010.3M☉ have undergone significant size growth since
z∼2, as expected; however, low mass galaxies have not. Finally, we
supplement our data with predominantly quiescent dwarf galaxies from
the core of the Fornax cluster, showing that the stellar mass-size
relation is continuous below 107M☉, but a more complicated
functional form is necessary to describe the relation.
Description:
We present structural catalogues for HFF galaxies that supplement the
data release (v3.9) of HFF-DeepSpace (Shipley et al.
(2018ApJS..235...14S 2018ApJS..235...14S)), a programme funded by NSF and STScI to produce
multi-wavelength photometric catalogs of the 12 cluster and parallel
field data of the Hubble Frontier Fields. The structural parameters
presented in these catalogues are obtained from the multi-wavelength
fitting tools, GalfitM and Galapagos-2, developed as part of the
MegaMorph project (see Haeussler et al. (2013MNRAS.430..330H 2013MNRAS.430..330H) for more
details). We provide a total of 12 catalogues - one for each cluster
and parallel field, where galaxies have been modelled with single
Sersic light profiles to obtain their effective radii, Sersic ind=
ices, and other structural parameters. Each catalogue is additionally
available as a fits table. In the fits tables, parameters which are
measured for each band are stored as seven-element arrays and
reported for the F125W, F435W, F606W, F814W, F105W, F140W, and F160W
bands, in this order. The Chebyshev polynomial coefficients are also
stored as arrays. Full details about how these catalogs are
constructed can be found in Nedkova et al. (2021MNRAS.506..928N 2021MNRAS.506..928N).

Note (1): Single-Sersic fit flag as follows:
-1 = not enough bands with data; not attempted
0 = not attempted
1 = fit started, but crashed
2 = fit completed
Note (2): includes number of pixels. Used to derive chi2 and chi2/nu
Note (3): Modelling parameter flag as follows:
0 = one or more of the parameters have run into fitting constraints
1 = none of the modelling parameters have run into fitting constraints
Note (4): A pixel scale of 0.06arcsec/pixel is needed to convert the measured
Re into units of arcseconds.
Note (5): Position angles are defined such that 0 is 'up', increasing
anticlockwise.
Note (6): We provide a python script for interpolating the Chebyshev
polynomials, available from the HFF-DeepSpace website:
