Abstract:
We analyse the Kormendy relations (KRs) of the two Frontier Fields
clusters, Abell S1063, at z=0.348, and MACS J1149.5+2223, at z=0.542,
exploiting very deep Hubble Space Telescope photometry and Very Large
Telescope (VLT)/Multi Unit Spectroscopic Explorer (MUSE) integral
field spectroscopy. With this novel data set, we are able to
investigate how the KR parameters depend on the cluster galaxy sample
selection and how this affects studies of galaxy evolution based on
the KR. We define and compare four different galaxy samples according
to (a) Sersic indices: early-type ('ETG'), (b) visual inspection:
'ellipticals', (c) colours: 'red', (d) spectral properties: 'passive'.
The classification is performed for a complete sample of galaxies with
mF814W≤22.5-ABmag (M*≥1010.0M☉). To derive robust
galaxy structural parameters, we use two methods: (1) an iterative
estimate of structural parameters using images of increasing size, in
order to deal with closely separated galaxies and (2) different
background estimations, to deal with the intracluster light
contamination. The comparison between the KRs obtained from the
different samples suggests that the sample selection could affect the
estimate of the best-fitting KR parameters. The KR built with ETGs is
fully consistent with the one obtained for ellipticals and passive. On
the other hand, the KR slope built on the red sample is only
marginally consistent with those obtained with the other samples. We
also release the photometric catalogue with structural parameters for
the galaxies included in the present analysis.
Description:
We analyse spectroscopically confirmed cluster galaxies of two HST
Frontier Fields (FF) clusters, Abell S1063 (z=0.348) and
MACSJ1149.5+2223 (z=0.542) in the F814W photometric band.
