Abstract:
The wavelength dependence of the Fundamental Plane projection along
the velocity dispersion axis, namely the Kormendy relation, is well
characterised at low-redshift, but poorly studied at intermediate
redshifts. The Kormendy relation provides information on the evolution
of the population of early-type galaxies (ETGs), therefore, by
studying it, we may shed light on the assembly processes of these
objects and their size evolution. Since studies at different redshifts
are generally conducted in different rest-frame wavebands,
investigating whether there is a wavelength dependence of the Kormendy
relation is fundamental to interpret the conclusions we might draw
from it.
We analyse the Kormendy relations of the three Hubble Frontier Fields
clusters, Abell S1063, at z=0.348, MACS J0416.1-2403, at z=0.396,
and MACS J1149.5+2223, at z=0.542, as a function of wavelength. This
is the first time the Kormendy relation of ETGs has been explored
consistently in such a large range of wavelength at intermediate
redshifts.
We exploit very deep Hubble Space Telescope photometry, ranging from
the observed B-band to the H-band, and VLT/MUSE integral field
spectroscopy. We improve the structural parameters estimation we
performed in a previous work (Tortorelli et al., 2018MNRAS.477..648T 2018MNRAS.477..648T,
Cat, J/MNRAS/477/648) by means of a newly developed Python package
called morphofit (Tortorelli & Mercurio 2023). Results: With its use
on cluster ETGs, we find that the Kormendy relation slopes smoothly
increase with wavelength from the optical to the near-infrared bands
in all three clusters, with the intercepts getting fainter at lower
redshifts due to the passivisation of the ETGs population. The slope
trend is consistent with previous findings at lower redshifts.
The slope increase with wavelength implies that smaller size ETGs are
more centrally concentrated than larger size ETGs in the near-infrared
with respect to the optical regime. Since different bands probe
different stellar populations in galaxies, the slope increase also
implies that smaller ETGs have stronger internal gradients with
respect to larger ETGs.
Description:
We present the structural parameters for 282 galaxies belonging to the
galaxy clusters Abell S1063 (95 members), MACS J0416.1-2403 (119
members) and MACS J1149.5+2223 (68 members). We classify as early-type
galaxies those having the Sersic index Nf814w≥2.5. The structural
parameters and their 1-sigma errors are estimated with the Python
package morphofit (Tortorelli & Mercurio 2023) in the seven wavebands
of the HST Frontier Fields data (F435W, F606W, F814W, F105W, F125W,
F140W, F160W).
