Galaxies frequently interact with nearby systems, a process that can significantly alter their morphology and star formation activity. However, spectroscopic studies of their faint…
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…
Cosmography with gravitational waves I: Taylor expansion in the low-redshift regime
Jonathan Morais, Rodrigo Gonçalves, Jailson Alcaniz
We evaluate the capability of current and next-generation gravitational-wave detectors, including Advanced LIGO, the Einstein Telescope, and DECIGO, to probe cosmographic parameter…
