Pixel color-magnitude diagrams of galaxies in the Fornax cluster using S-PLUS images
C. G. Escudero, A. V. Smith Castelli, F. R. Faifer +4
Galaxy clusters are the largest gravitationally bound systems in the Universe and, as such, play an important role in cosmological studies. An important resource for studying their…

The Southern Photometric Local Universe Survey (S-PLUS) aims to map 9300 deg of the Southern sky using the Javalambre filter system of 12 optical bands, 5 Sloan-like…
The Photometric Metallicity and Carbon Distributions of the Milky Way's Halo and Solar Neighborhood from S-PLUS Observations of SDSS Stripe 82
Devin D. Whitten, Vinicius M. Placco, Timothy C. Beers +14
We report photometric estimates of effective temperature, , metallicity, [Fe/H], carbonicity, [C/Fe], and absolute carbon abundances, , for over 700,000 st…
Recovering the origins of the lenticular galaxy NGC 3115 using multi-band imaging
Maria Luisa Buzzo, Arianna Cortesi, Jose A. Hernandez-Jimenez +16
A detailed study of the morphology of lenticular galaxies is an important way to understand how this type of galaxy formed and evolves over time. Decomposing a galaxy into its comp…
Physical and kinematic conditions of the local merging galaxy NGC 1487
M. L. Buzzo, B. Ziegler, P. Amram +6
We present optical VLT/MUSE integral field spectroscopy data of the merging galaxy NGC 1487. We use fitting techniques to study the ionized gas emission of this merger and its main…
A preserved high-z compact progenitor in the heart of NGC3311 revealed with MUSE 2D stellar population analysis
C. E. Barbosa, C. Spiniello, M. Arnaboldi +3
Massive early-type galaxies are believed to be the end result of an extended mass accretion history. The stars formed in situ very early on in the initial phase of the assembly mig…
An environmental dependence of the physical and structural properties in the Hydra Cluster galaxies
Ciria Lima-Dias, Antonela Monachesi, Sergio Torres-Flores +20
The nearby Hydra Cluster (50 Mpc) is an ideal laboratory to understand, in detail, the influence of the environment on the morphology and quenching of galaxies in dense envir…
One hundred SMUDGes in S-PLUS: ultra-diffuse galaxies flourish in the field
C. E. Barbosa, D. Zaritsky, R. Donnerstein +19
We present the first systematic study of the stellar populations of ultra-diffuse galaxies (UDGs) in the field, integrating the large area search and characterization of UDGs by th…
