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: The stellar mass function of quiescent and star-forming galaxies at 0.05 <= z <= 0.2
F. D. Arizo-Borillo, C. Lopez-Sanjuan, I. Pintos-Castro +22
Aims. We derive the stellar mass function (SMF) of quiescent and star-forming galaxies at z <= 0.2 using 12-band optical photometry from the third data release (DR3) of the Javalam…
J-PLUS: Bayesian object classification with a strum of BANNJOS
A. del Pino, C. López-Sanjuan, A. Hernán-Caballero +22
With its 12 optical filters, the Javalambre-Photometric Local Universe Survey (J-PLUS) provides an unprecedented multicolor view of the local Universe. The third data release (DR3)…
Galaxy merger challenge: A comparison study between machine learning-based detection methods
B. Margalef-Bentabol, L. Wang, A. La Marca +14
Various galaxy merger detection methods have been applied to diverse datasets. However, it is difficult to understand how they compare. We aim to benchmark the relative performance…
The local Universe in the era of large surveys -- III. Radial activity profiles of S0 galaxies
J. L. Tous, J. M. Solanes, J. D. Perea +1
Spatially resolved MaNGA's optical spectra of 1072 present-day lenticular (S0) galaxies, dimensionally reduced from a principal component analysis (PCA), are used to determine thei…
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…
Bridging the gap in the mass-size relation of compact galaxies with MaNGA
P. Grèbol-Tomàs, A. Ferré-Mateu, H. Domínguez-Sánchez
We present the analysis of the full MaNGA DR17 sample to characterize its population of compact galaxies. We focus on galaxies that fill the stellar mass (M) gap between…
The origin of star-forming rings in S0 galaxies
J. L. Tous, H. Domínguez-Sánchez, J. M. Solanes +1
Spatially resolved integral field spectroscopic maps in a sample of S0 galaxies from the MaNGA survey have unveiled the existence of inner rings ($\langle R\rangle\sim 1\,R_\…
Capturing the physics of MaNGA galaxies with self-supervised Machine Learning
Regina Sarmiento, Marc Huertas-Company, Johan H. Knapen +4
As available data sets grow in size and complexity, advanced visualization tools enabling their exploration and analysis become more important. In modern astronomy, integral field…
A duality in the origin of bulges and spheroidal galaxies
L. Costantin, P. G. Pérez-González, J. Méndez-Abreu +11
Studying the resolved stellar populations of the different structural components which build massive galaxies directly unveils their assembly history. We aim at characterizing the…
The CANDELS/SHARDS multi-wavelength catalog in GOODS-N: Photometry, Photometric Redshifts, Stellar Masses, Emission line fluxes and Star Formation Rates
Guillermo Barro, Pablo G. Perez-Gonzalez, Antonio Cava +52
We present a WFC3 F160W (-band) selected catalog in the CANDELS/GOODS-N field containing photometry from the ultraviolet (UV) to the far-infrared (IR), photometric redshifts and…

SHARDS: Constraints on the dust attenuation law of star-forming galaxies at z~2
M. Tress, E. Mármol-Queraltó, I. Ferreras +11
We make use of SHARDS, an ultra-deep (<26.5AB) galaxy survey that provides optical photo-spectra at resolution R~50, via medium band filters (FWHM~150A). This dataset is combined w…
gradients driven by IMF variation: Large impact on dynamical stellar mass estimates
M. Bernardi, R. K. Sheth, H. Dominguez-Sanchez +4
Within a galaxy the stellar mass-to-light ratio is not constant. Spatially resolved kinematics of nearby early-type galaxies suggest that allowing for a variable initial mass…
Stellar mass functions and implications for a variable IMF
M. Bernardi, R. K. Sheth, J. -L. Fischer +6
Spatially resolved kinematics of nearby galaxies has shown that the ratio of dynamical- to stellar population-based estimates of the mass of a galaxy () correlat…
