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,…

The miniJPAS survey: Dissecting galaxy properties across environments with spatially resolved photometry

J. E. Rodríguez-Martín, R. M. González Delgado, L. A. Díaz-García +27

The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) is an ongoing survey mapping thousands of square degrees in the Northern Hemisphere using 56 narrow…

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…

Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Mapping formation pathways of nuclear star clusters across galaxies

Francesca Pinna, Isabel Pérez, Anna Ferré-Mateu +21

Nuclear star clusters (NSCs) are dense, compact stellar systems only a few parsecs across, located at galaxy centers. Their small sizes make them difficult to resolve spatially. NS…

J-PAS: First Identification, Physical Properties and Ionization Efficiency of Extreme Emission Line Galaxies

A. Giménez-Alcázar, R. Amorín, J. M. Vílchez +32

Extreme emission line galaxies (EELGs) are key tracers of intense star formation and potential analogues of the sources that reionized the early Universe. Their low-redshift counte…

J-PAS: A value-added catalogue of optical line intensities for nebular emission galaxies (JOLINES)

J. A. Fernández-Ontiveros, C. López-Sanjuan, A. Hernán-Caballero +38

We present the value-added catalogue JOLINES (J-PAS optical line intensities for nebular emission galaxies), which provides emission-line fluxes in galaxies at from the spectrophot…
