S-PLUS: Beyond Spectroscopy IV. Stellar Parameters and Elemental-abundance Ratios for Six Million Stars from DR4 and First Results for the Magellanic Clouds
Yang Huang, Timothy C. Beers, Kai Xiao +18
We combine narrow/medium-band filter photometry from the Southern Photometric Local Universe Survey (S-PLUS) DR4 with ultra broad-band filter photometry from Gaia EDR3 to derive fu…
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…
The Southern Photometrical Local Universe Survey (S-PLUS): searching for metal-poor dwarf galaxies
M. Grossi, D. R. Gonçalves, A. C. Krabbe +22
The metal content of a galaxy's interstellar medium reflects the interplay between different evolutionary processes such as feedback from massive stars and the accretion of gas fro…
The S-PLUS Fornax Project (S+FP): Mapping H+[NII] emission in 77 Fornax galaxy members reaching 4 Rvir
A. R. Lopes, A. V. Smith Castelli, A. C. Krabbe +31
The Fornax cluster, the second-largest galaxy cluster within 20 Mpc, presents an ideal environment for studying environmental effects on galaxy evolution. Utilizing data from the S…
An Unsupervised Machine Learning Approach to Identify Spectral Energy Distribution Outliers: Application to the S-PLUS DR4 data
F. Quispe-Huaynasi, F. Roig, N. Holanda +12
Identification of specific stellar populations using photometry for spectroscopic follow-up is a first step to confirm and better understand their nature. In this context, we prese…
