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…

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-PLUS: Turning Off the Bright Stars

Sepideh Eskandarlou, Mohammad Akhlaghi, Johan H. Knapen +23

Photometric surveys require precise point spread function (PSF) characterization, as it varies across filters and is crucial for accurate photometry and low surface brightness (LSB…

J-PAS: Discovery of RaJav, a bright spatially extended Ly Nebula at z=2.25

P. T. Rahna, M. Akhlaghi, J. A. Fernández-Ontiveros +29

We report the discovery of a massive and potentially largest Ly Nebula, RaJav, at z=2.25, associated with a quasar pair: the bright SDSS~J162029.07+433451.1 (hereafter J1620+433…

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…
