J-PAS: forecast on the primordial power spectrum reconstruction

G. Martínez-Somonte, Airam Marcos-Caballero, Enrique Martínez-González, Antonio L. Maroto et autres

Abstract We investigate the capability of the J-PAS survey to constrain the primordial power spectrum using a non-parametric Bayesian method. Specifically, we analyze simulated power spectra generated by an oscillatory primordial feature template motivated by non-standard inflation. The feature is placed within …

The miniJPAS and J-NEP Surveys: Machine Learning for Star-Galaxy Separation

Ana Paula Jeakel, Valerio Marra, Rodrigo von Marttens, Siddhartha Gurung-López et autres

We present a supervised machine learning classification of sources from the Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS) Pathfinder datasets: miniJPAS and J-NEP. Leveraging crossmatches with spectroscopic and photometric catalogs, we construct a robust labeled dataset comprising 14,594 sources classified …

J-PAS: First identification, physical properties, and ionization efficiency of extreme emission line galaxies

A. Giménez-Alcázar, R. Amorín, J. M. Vı́lchez, Antonio Hernán-Caballero et autres

Context. Extreme emission line galaxies (EELGs) are believed to significantly contribute to the star formation activity and mass assembly in galaxies. EELGs likely also play a leading role in the cosmic re-ionization as their interstellar medium may allow a significant fraction of …

Unveiling the small-scale web around galaxies with miniJPAS and DESI

Daniela Galárraga-Espinosa, Guinevere Kauffmann, Silvia Bonoli, Luisa Lucie-Smith et autres

We present the first statistical observational study detecting filaments in the immediate surroundings of galaxies, i.e. the local web of galaxies. Simulations predict that cold gas, the fuel for star formation, is channeled through filamentary structures into galaxies. Yet, direct observational evidence …

The miniJPAS survey quasar selection

Ignasi Pérez-Ràfols, L. Raul Abramo, G. Martínez-Solaeche, Matthew M. Pieri et autres

Aims . Quasar catalogues from narrow-band photometric data are used in a variety of applications, including targeting for spectroscopic follow-up, measurements of supermassive black hole masses, or baryon acoustic oscillations. Here, we present the final quasar catalogue, including redshift estimates, from the …

J-PAS: A neural network approach to single stellar population characterisation

H. Domínguez Sánchez, P. Coelho, Gustavo A. Bruzual, Antonio Hernán-Caballero et autres

J-PAS (Javalambre Physics of the Accelerating Universe Astrophysical Survey) will present a groundbreaking photometric survey covering 8500 deg 2 of the visible sky from Javalambre, capturing data in 56 narrow-band filters. This survey promises to revolutionise galaxy evolution studies by observing ∼10 …

J-PAS: A Neural Network Approach to Single Stellar Population Characterization

H. Domínguez Sánchez, P. Coelho, Gustavo A. Bruzual, Antonio Hernán-Caballero et autres

J-PAS (Javalambre Physics of the Accelerating Universe Astrophysical Survey) will present a groundbreaking photometric survey covering 8500 deg$^2$ of the visible sky from Javalambre, capturing data in 56 narrow band filters. This survey promises to revolutionize galaxy evolution studies by observing $\sim$10$^8$ …

Detecting Phenotypic Variability in Lupinus angustifolius Through Ecogeographic Land Characterization

Alfredo Garcia, Fernando García López, Maris Luisa Rubio Teso, Jose Maria Iriondo Alegria et autres

Abstract Germplasm banks hold substantial potential across numerous branches of life sciences. However, this potential remains underutilized, partly due to the limited and incomplete characterization of the accessions. To address this issue, we propose the use of Ecogeographical Land Characterization (ELC) maps …

J-PAS: Forecasting constraints on Neutrino Masses

Gabriel Rodrigues, Antonio J. Cuesta, Jailson Alcaniz, Miguel Aparicio Resco et autres

The large-scale structure survey J-PAS is taking data since October 2023. In this work, we present a forecast based on the Fisher matrix method to establish its sensitivity to the sum of the neutrino masses. We adapt the Fisher Galaxy Survey Code …

J-PAS and PFS surveys in the era of dark energy and neutrino mass measurements

Fuxing Qin, Y.T. Wang, Gong‐Bo Zhao, Antonio J. Cuesta et autres

Fisher-matrix forecasts are presented for the cosmological surveys of the Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS) and the Subaru Prime Focus Spectrograph (PFS). The wide, low-redshift coverage of J-PAS and the high-density, high-redshift mapping of PFS are strongly complementary: …
