AI and The Enclosure of the Scientific Commons
P. K. G. Williams
The scientific literature can be viewed as an "information commons:" an intangible resource that "no one owns and is shared by everyone." There are well-established economic and po…
J-PAS & FLAMINGO: Cosmic voids and void galaxies in the gravitational landscape of photometric surveys
J. A. Mansour, B. McCarthy, L. J. Liivamägi +34
Photometric surveys offer a powerful way to map the large-scale structure of the Universe, but their redshift errors complicate the identification of cosmic voids, challenging stud…
The impact of FRB dispersion measure probability distribution functions on cosmographic estimates
Thais Lemos, Rodrigo Gonçalves, Jailson Alcaniz
Recent cosmological observations have reopened the discussion about the model that best describes the dynamics of the Universe, highlighting the need for cosmological model-indepen…
Measurements of the Angular Homogeneity Scale from DESI DR1
Mariana Lopes-Dias, Carlos A. P. Bengaly, Xiaoyun Shao +4
The study of the large-scale distribution of galaxies provides essential information for testing the standard cosmological model, namely the CDM paradigm. This scenario is based…
OJALÁ: Optimizing J-PAS Astronomy for Large-scale Analysis. A foundation model for the SED of galaxies, QSOs and stars
G. Martínez-Solaeche, R. M. González Delgado, R. García-Benito +37
The advent of large-scale surveys requires efficient ML techniques to exploit the information of massive datasets. We present OJALA, a transformer-based autoregressive foundation m…
Stellar characterization with photometric colors from J-PLUS and 2MASS surveys
J. F. Aguilar, P. Cruz, E. Solano +18
Aims. We aim at deriving stellar atmospheric parameters based on the photometric data from the Javalambre Photometric Local Universe Survey (J-PLUS) in addition to near-infrared ph…
J-PAS: unprecedented precision in stellar populations of diffuse tidal features
Sepideh Eskandarlou, Mohammad Akhlaghi, Francisco Arizo-Borillo +38
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…
