Blowing star formation away in AGN hosts (BAH) -- V: The Feeding-Feedback Cycle in local AGNs as revealed by their stellar populations

Rogério Riffel, Rogemar A. Riffel, Gabriel L. Souza-Oliveira +9

We present a spatially resolved analysis of the stellar populations in the inner kiloparsec of NGC 3884, 3C 293, and CGCG 012-070. Using near-infrared spectroscopy, we reconstruct…

ELMA: ELlipse-based bar MAjor axis estimator

Bruna R. Bragança de Lima, Andressa Wille, Rafael S. de Souza +1

Galactic bars are key non-axisymmetric structures in disk galaxies, driving angular-momentum redistribution and contributing to secular evolution, central mass build-up, and the fo…

Lightstack: A Python Package for Creating Photometric Data Cubes

Andressa Wille, Rafael S. de Souza, Ana L. Chies-Santos +3

Multi-band photometry traces diverse physical processes across a wide range of wavelengths. In recent decades, this field has been driven by the rapid growth of multi-imaging datas…

PowerSpectR: An R Package for Radial Power Spectrum Estimation

Rafael S. de Souza

I present here PowerSpectR, an R package for computing and visualizing median-based radial Fourier power spectra from imaging data. Power spectra provide a representation of spatia…

Modeling Globular Cluster Counts with Bayesian Latent Models

Rafael S. de Souza, Ana L. Chies-Santos

We present a Bayesian latent model to describe the scaling relation between globular cluster populations and their host galaxies, updating the framework proposed in de Souza 2015.…
