J-PAS & FLAMINGO: Cosmic voids and void galaxies in the gravitational landscape of photometric surveys
J. A. Mansour, B. McCarthy, L. J. Liivamägi +34
The paper presents a method that uses a quasi‑gravitational potential field to identify dynamically dominant cosmic voids and their galaxies in photometric surveys like J‑PAS, show…
Cosmic homogeneity: the effect of redshift-space distortions and bias and cosmological constraints
Xiaoyun Shao, Rodrigo Gonçalves, Carlos A. P. Bengaly +2
We present a novel cosmological analysis based on the angular correlation dimension curve, a cumulative statistic derived from the two-point correlation function. Unlike trad…
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 base…
OJALÃ: Optimizing J-PAS Astronomy for Large-scale Analysis. A foundation model for the SED of galaxies, QSOs and stars
G. MartÃnez-Solaeche, R. M. González Delgado, R. GarcÃa-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 +17
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…
