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>
