clusters are ideal laboratories for studying galaxy
evolution in dense environments, and current
multiwavelength surveys allow us to observe changes in the
colors and morphology of galaxies across different
filters. In this work, we utilize data from the Southern
Photometric Local Universe Survey (S-PLUS), which includes
12 filters in the visible range of the spectrum, to
analyze galaxies as a whole and to perform bulge-disc
decomposition. Studying the distinct components of a
cluster galaxy separately is crucial, as these components
are influenced by the environment in different ways. We
investigate the behavior of structural (Sérsic index and
effective radius) and physical (stellar mass and star
formation rate) properties of the galaxies and correlate
them with the environment (clustercentric distance, local
density, and substructure). As a result, we found that the
star-forming galaxies in the Hydra cluster have bluer
bulges compared to their discs, indicating that the
environment is quenching these galaxies from the outside
in.</p>

groups (CGs) provide a valuable opportunity to study how
galaxy interactions influence physical and structural
parameters due to their high density and low-velocity
dispersion. We investigated a sample of 340 CGs, including
1,092 galaxies, and compared it with a control group of
2,300 field galaxies to explore these effects. Our
analysis of the Effective Radius–Sérsic Index (Re-n) plane
revealed a bimodal distribution among transitioning
galaxies in CGs. We define the transition galaxies as
those with redder colors (u-r > 2.3) and Sérsic indices
(n < 2.5). This suggests the presence of a distinct
population of smaller, more compact galaxies in CGs, a
population that is absent in the control sample. This
observation indicates that galaxies in CGs may undergo
significant morphological changes. Around 27% of the CGs
are part of larger groups, which we classify as
non-isolated CGs. Transition galaxies in isolated CGs are
more likely to cluster in a denser region of the Re–n
plane when n < 1.75. In contrast, transition galaxies
in non-isolated CGs show a more gradual increase in n
values, indicating that these galaxies have experienced
morphological transformations and are the main
contributors to the distribution of more compact galaxies
in the Re–n plane among all transition galaxies in CGs.
Moreover, galaxies in non-isolated CGs display lower
specific star formation rates and a higher proportion of
quenched galaxies compared to their isolated
counterparts. Furthermore, a spatially resolved analysis
was performed using integral field spectroscopy (IFS) data
to study both ionized gas and stellar components in 549
galaxies in CGs and 1,098 field galaxies. Galaxies in CGs
tend to have older stellar populations, although
star-forming galaxies show similar <span><span>Σ</span></span>SFR
profiles to those in the field. However, galaxies with
nuclear activity in CGs exhibit higher <span><span>Σ</span></span>SFR
values and flatter slopes. No significant differences were
found in the metallicity gradients between CG and field
galaxies. In summary, we highlight the critical role of
the environment in the evolution of galaxies in CGs,
emphasizing how dense environments and interactions
accelerate morphological transformation and the quenching
process.</p>
