Tabular foundation models for the estimation of probabilistic quasar photometric redshifts in S-PLUS
Raquel R. Valença, Lilianne Nakazono, Rafael Izbicki +6
We assess whether tabular foundation models can be used as off-the-shelf probabilistic photometric-redshift estimators for quasars in the 12-band S-PLUS DR6 survey, where colour-re…
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…
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…
J-PAS: Semi-Supervised Sim-to-Obs Transfer for Robust Star--Galaxy--Quasar Classification
Daniel López-Cano, L. Raul Abramo, L. Nakazono +28
Modern studies in astrophysics and cosmology increasingly rely on simulations and cross-survey analyses, yet differences in data generation, instrumentation, calibration, and unmod…
ELEPHANT: ExtragaLactic alErt Pipeline for Hostless AstroNomical Transients
P. J. Pessi, R. Durgesh, L. Nakazono +11
Context. Transient astronomical events that exhibit no discernible association with a host galaxy are commonly referred to as hostless. These rare phenomena are associated with ext…
Panel Discussion: Practical Problem Solving for Machine Learning
Guillermo Cabrera, Sungwook E. Hong, Lilianne Nakazono +2
Machine Learning is a powerful tool for astrophysicists, which has already had significant uptake in the community. But there remain some barriers to entry, relating to proper unde…
Data Release 2 of S-PLUS: accurate template-fitting based photometry covering 1000 square degrees in 12 optical filters
F. Almeida-Fernandes, L. Sampedro, F. R. Herpich +26
The Southern Photometric Local Universe Survey (S-PLUS) is an ongoing survey of 9300 deg in the southern sky in a 12-band photometric system. This paper presents the seco…
Astro2020 Project White Paper: The Cosmic Accelerometer
Stephen S. Eikenberry, Anthony Gonzalez, Jeremy Darling +15
We propose an experiment, the Cosmic Accelerometer, designed to yield velocity precision of cm/s with measurement stability over years to decades. The first-phase Cosmic A…
