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-HERTz: J-PLUS Heritage Exploration of Radio Targets at z 5

D. Fernández Gil, J. A. Fernández-Ontiveros, C. López-Sanjuan +17

We introduce J-HERTz (J-PLUS Heritage Exploration of Radio Targets at ), a new multi-wavelength catalog that combines optical narrow-band photometry from J-PLUS, infrared ob…

J-PAS: Forecasting constraints on Neutrino Masses

Gabriel Rodrigues, Antonio J. Cuesta, Jailson Alcaniz +30

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…

Andromeda's tenuous veil: A likely Milky Way nebula projected toward M31

A. Lumbreras-Calle, J. A. Fernández-Ontiveros, R. Infante-Sainz +10

A large, faint nebula was unexpectedly discovered near M31 using narrowband [O III] images. Its apparent size and the lack of a clear counterpart at other wavelengths make it uniqu…

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

Daniela Galárraga-Espinosa, Guinevere Kauffmann, Silvia Bonoli +23

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 ga…

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…
