J-PLUS: Spectral classification and photometric redshifts for 79 million sources in the fourth data release
A. Hernán-Caballero, H. Vázquez Ramió, C. López-Sanjuan +20
We present spectral classifications and photometric redshifts for 79.2 million sources up to an r-band magnitude of 22 in Data Release 4 of the Javalambre Photometric Local Univers…
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 miniJPAS survey: Maximising the photo-z accuracy from multi-survey datasets with probability conflation
A. Hernán-Caballero, M. Akhlaghi, C. López-Sanjuan +35
We present a new method for obtaining photometric redshifts (photo-z) for sources observed by multiple photometric surveys using a combination (conflation) of the redshift probabil…
J-NEP: 60-band photometry and photometric redshifts for the James Webb Space Telescope North Ecliptic Pole Time-Domain Field
A. Hernán-Caballero, C. N. A. Willmer, J. Varela +28
The J-PAS survey will observe ~1/3 of the northern sky with a set of 56 narrow-band filters using the dedicated 2.55 m JST telescope at the Javalambre Astrophysical Observatory. Pr…
The miniJPAS survey quasar selection I: Mock catalogues for classification
Carolina Queiroz, L. Raul Abramo, Natália V. N. Rodrigues +27
In this series of papers, we employ several machine learning (ML) methods to classify the point-like sources from the miniJPAS catalogue, and identify quasar candidates. Since no r…
The miniJPAS Survey: A Study on Wavelength Dependence of the Photon Response Non-uniformity of the JPAS-{\it Pathfinder} Camera
Kai Xiao, Haibo Yuan, J. Varela +20
Understanding the origins of small-scale flats of CCDs and their wavelength-dependent variations plays an important role in high-precision photometric, astrometric, and shape measu…
The miniJPAS survey: the photometric redshift catalogue
A. Hernán-Caballero, J. Varela, C. López-Sanjuan +30
MiniJPAS is a ~1 deg^2 imaging survey of the AEGIS field in 60 bands, performed to demonstrate the scientific potential of the upcoming JPAS survey. Full coverage of the 3800-9100…
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…
The miniJPAS survey: a preview of the Universe in 56 colours
S. Bonoli, A. Marín-Franch, J. Varela +166
The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will soon start to scan thousands of square degrees of the northern extragalactic sky with a unique…
The miniJPAS survey: star-galaxy classification using machine learning
P. O. Baqui, V. Marra, L. Casarini +31
Future astrophysical surveys such as J-PAS will produce very large datasets, which will require the deployment of accurate and efficient Machine Learning (ML) methods. In this work…
J-PLUS: measuring emission line fluxes in the nearby universe
R. Logroño-García, G. Vilella-Rojo, C. López-Sanjuan +29
In the present paper we aim to validate a methodology designed to extract the Halpha emission line flux from J-PLUS photometric data. J-PLUS is a multi narrow-band filter survey ca…
J-PLUS: Morphological star/galaxy classification by PDF analysis
C. López-Sanjuan, H. Vázquez Ramió, J. Varela +29
Our goal is to morphologically classify the sources identified in the images of the J-PLUS early data release (EDR) into compact (stars) or extended (galaxies) using a suited Bayes…
J-PLUS: The Javalambre Photometric Local Universe Survey
A. J. Cenarro, M. Moles, D. Cristóbal-Hornillos +119
J-PLUS is an ongoing 12-band photometric optical survey, observing thousands of square degrees of the Northern hemisphere from the dedicated JAST/T80 telescope at the Observatorio…
The ALHAMBRA survey: 2-D analysis of the stellar populations in massive early-type galaxies at z < 0.3
I. San Roman, A. J. Cenarro, L. A. Díaz-García +29
We present a technique that permits the analysis of stellar population gradients in a relatively low cost way compared to IFU surveys analyzing a vastly larger samples as well as o…
