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 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…
AstroInspect: a web-based system to organize, assess, and visually inspect astronomical objects
Natanael M. Cardoso, Claudia Mendes de Oliveira, Angela C. Krabbe +9
The rapid growth of imaging and spectroscopic surveys has intensified the need for efficient tools that support visual inspection, a practice that remains essential for tasks such…
Recent advances on multimessenger astrophysics: Centaurus A, GW 170817, and KM3-230213A
Cainã de Oliveira, Vitor de Souza
We review recent advances in multimessenger astrophysics, with particular emphasis on Centaurus A and on two pivotal events: the gravitational-wave detection GW 170817 and the ultr…
The planetary nebula NGC 3132 revisited: high definition 3D photoionization model
H. Monteiro, C. Mendes de Oliveira, P. Amram +6
We present a detailed 3D photoionization model of the planetary nebula NGC 3132, constrained by the latest observations. Using the MOCASSIN code, the model incorporates integrated…
The S-PLUS Transient Extension Program: Imaging Pipeline, Transient Identification, and Survey Optimization for Multi-Messenger Astronomy
A. Santos, C. D. Kilpatrick, C. R. Bom +9
We present the S-PLUS Transient Extension Program (STEP): a supernova and fast transient survey conducted in the southern hemisphere using data from the Southern Photometric Local…
