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…
Analysis of spatially resolved stellar populations and emission line properties in nearby galaxies with J-PLUS data. II-Results for the M51 group and first comparison with the M101 group
J. Thainá-Batista, R. Cid Fernandes, R. M. González Delgado +19
We characterize the spatially resolved stellar population and emission-line properties of galaxies in the M51 group using the same methodology previously applied to the M101 group,…
Exploring the spatially-resolved capabilities of the J-PAS survey with Py2DJPAS
J. E. Rodríguez-Martín, L. A. Díaz-García, R. M. González Delgado +27
We present Py2DJPAS, a Python-based tool to automate the analysis of spatially resolved galaxies in the \textbf{miniJPAS} survey, a 1~deg precursor of the J-PAS survey, using t…
J-PLUS: Spectroscopic validation of H emission line maps in spatially resolved galaxies
P. T. Rahna, M. Akhlaghi, C. López-Sanjuan +22
We present a dedicated automated pipeline to construct spatially resolved emission H+[NII] maps and to derive the spectral energy distributions (SEDs) in 12 optical filters (fiv…
The environment as a driver of galaxy evolution with the miniJPAS survey
Julio E. Rodríguez-Martín
This thesis aims at discerning the effect of environment on galaxy evolution and on the properties of galaxies, using the data from the miniJPAS survey, a 1~deg survey that use…
Exploring Galaxy Properties of eCALIFA with Contrastive Learning
G. Martínez-Solaeche, R. García-Benito, R. M. González Delgado +4
Contrastive learning (CL) has emerged as a potent tool for building meaningful latent representations of galaxy properties across a broad spectrum of wavelengths, ranging from opti…
The miniJPAS survey. Evolution of the luminosity and stellar mass functions of galaxies up to
L. A. Díaz-García, R. M. González Delgado, R. García-Benito +22
We aim at developing a robust methodology for constraining the luminosity and stellar mass functions (LMFs) of galaxies by solely using data from multi-filter surveys and testing t…
The miniJPAS survey quasar selection III: Classification with artificial neural networks and hybridisation
G. Martínez-Solaeche, Carolina Queiroz, R. M. González Delgado +28
This paper is part of large effort within the J-PAS collaboration that aims to classify point-like sources in miniJPAS, which were observed in 60 optical bands over 1 deg$^2…
The miniJPAS survey: The role of group environment in quenching the star formation
R. M. González Delgado, J. E. Rodríguez-Martín, L. A. Díaz-García +32
The miniJPAS survey has observed deg on the AEGIS field with 60 bands (spectral resolution of ) in order to demonstrate the capabilities of the Javalambre-P…
The miniJPAS survey: Identification and characterization of the emission line galaxies down to in the AEGIS field
G. Martínez-Solaeche, R. M. González Delgado, R. García-Benito +28
The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) is expected to map thousands of square degrees of the northern sky with 56 narrowband filters in th…
The miniJPAS survey: Identification and characterization of galaxy populations with the J-PAS photometric system
R. M. González Delgado, L. A. Díaz-García, A. de Amorim +39
J-PAS will soon start imaging 8000 deg2 of the northern sky with its unique set of 56 filters (R 60). Before, we observed 1 deg2 on the AEGIS field with an interim camera wi…
