Star formation and morphological trends in the Antlia cluster: Probing environmental influence out to 5R200

Ciria Lima-Dias, Antonela Monachesi, Gissel P. Montaguth +48

Galaxy evolution in dense environments such as clusters is strongly affected by environmental processes that can alter both morphology and star formation activity. We investigate t…

CLAS+: A large catalog of Changing-Look AGN candidates selected through S-PLUS narrow-band photometry

L. Nakazono, L. L. Oliveira, R. R. Valença +11

Changing-look active galactic nuclei (CLAGN) exhibit rapid spectral transitions on timescales of months to years, challenging standard AGN unification models and providing unique i…

The S-PLUS Fifth Data-Release: Over 4500 square degrees of the Southern Sky and a multicolor view of the Hydra and Antlia galaxy clusters

Erik Vinicius Rodrigues de Lima, Gustavo Bernhard Oliveira Schwarz, Fábio Rafael Herpich +55

We present the 5th data release (DR5) of the Southern Photometric Local Universe Survey (S-PLUS), covering 4592 square degrees across 2491 fields. Observations were conducted with…

Variables in S-PLUS: I. Multiband period-luminosity relations and reddening maps of the Magellanic Clouds using classical Cepheids

Debasish Hazarika, Carlos E. Ferreira Lopes, Márcio Catelan +12

Aims. Classical Cepheids (CCs) are fundamental standard candles for the extragalactic distance scale through their period-luminosity (P-L) relations. Although well calibrated in br…

The Metallicity Gradient of Sagittarius Dwarf Spheroidal Galaxy Prior to Infall Constrained by S-PLUS Observations of its Tidal Stream

Felipe Almeida-Fernandes, Guilherme Limberg, Hélio D. Perottoni +16

We study the metallicity distribution along the Sagittarius (Sgr) stream using photometric metallicities from S-PLUS DR4, combined with Gaia DR3 kinematics and APOGEE DR17 spectros…

Galaxies caught in transition: the role of group environment in shaping the mass-size relation in the local Universe

Gissel P. Montaguth, Claudia Mendes de Oliveira, Ciria Lima-Dias +8

The stellar mass-size relation is a sensitive probe of how environment shapes galaxy structure. We analyse this relation in the local Universe for galaxies in compact groups (CGs),…

Galaxy evolution in compact groups - III. Structural analysis of galaxies and dynamical state of non-isolated compact groups

Gissel P. Montaguth, Ana Laura O'Mill, Claudia Mendes de Oliveira +17

Compact Groups (CGs) of galaxies are dense systems where projected separations are comparable to their optical diameters. A subset - non-isolated CGs - are embedded within major st…

Spatially-resolved spectro-photometric SED Modeling of NGC 253's Central Molecular Zone I. Studying the star formation in extragalactic giant molecular clouds

Pedro K. Humire, Subhrata Dey, Tommaso Ronconi +29

Studying the interstellar medium in nearby starbursts is essential for understanding the physical mechanisms driving these objects, thought to resemble young star-forming galaxies.…

Galaxy evolution in compact groups II. Witnessing the influence of major structures in their evolution

Gissel P. Montaguth, Antonela Monachesi, Sergio Torres-Flores +15

Compact groups (CGs) of galaxies are extreme environments for morphological transformations and the cessation of star formation. Though initially considered isolated, it is now rec…

Bulge-disc decomposition of the Hydra cluster galaxies in 12 bands

Ciria Lima-Dias, Antonela Monachesi, Sergio Torres-Flores +15

When a galaxy falls into a cluster, its outermost parts are the most affected by the environment. In this paper, we are interested in studying the influence of a dense environment…
