Galactic Archaeology with the Subaru `Ånohi`ula Prime Focus Spectrograph Strategic Program
Masashi Chiba, Rosemary F. G. Wyse, Evan N. Kirby +47
The recently commissioned Subaru `Ånohi`ula Prime Focus Spectrograph (PFS) will obtain spectra from nearly 2,400 fibers that cover 1.24 square degrees. The 360 night Subaru Strate…
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…
SAGUI: SED-based Segmentation of Multi-band Galaxy Images -- Application to JADES in GOODS-South
Rafael S. de Souza, Andressa Wille, Shravya Shenoy +11
We present sagui, a modular framework for the analysis of multi-band imaging data in spatially resolved galaxies, with synergies to integral-field spectroscopy (IFS). Building on t…
The contribution of the color space in LSST-like photometry for the selection of extragalactic globular cluster candidates
Nicholas Schweder-Souza, Ana L. Chies-Santos, Rafael S. de Souza +16
Globular clusters (GCs) are excellent tracers of their host galaxies' evolutionary histories. Traditional methods for identifying GCs in galaxies rely on cuts over photometric cata…
Tracing the relic nature of compact galaxies through their globular cluster systems
Micheli T. Moura, Ana L. Chies-Santos, Cristina Furlanetto +6
We investigate the synthetic model of globular cluster (GC) systems of 17 compact massive galaxies (CMGs) from the Illustris TNG100 simulation to explore their connection with mass…
