The Javalambre Variability Survey (J-VAR) is the time-domain extension of the Javalambre Photometric Local Universe Survey (J-PLUS). J-VAR revisits up to eleven times the regions already observed by J-PLUS, using a subset of seven filters from the main survey (broad-band filters g, r, and i, and narrow-band filters J0395, J0515, J0660, and J0861). Thanks to this strategy, the survey has...

3. Insights into Milky Way disk star formation history with J-PLUS

We aim to recover the SFH of the Milky Way disc, disentangling its chemically distinct components, by combining J-PLUS DR3 photometry
with Gaia astrometry. We fit magnitudes and parallaxes of 1.38 million dust-corrected stars using a Bayesian multiple-isochrone fitting technique. The bright region of the colour–absolute-magnitude diagramconstrains stellar ages, while the faint region provides...

4. Extreme emission line galaxies in J-PLUS: walking through synergies towards the early Universe

Alejandro Lumbreras (CEFCA)

Extreme emission line galaxies (EELGs) constitute a population of unique systems undergoing very intense events of star formation. These objects are very rare in our immediate environment, but they are crucial for understanding the physical limits of star formation, and most importantly, the formation of the first galaxies, during the early history of the Universe. While EELGs were abundant...

12. J-HERTz: Studying AGN feedback and galaxy evolution with LF radio and optical narrow-band observations

David Fernández.

02/10/2025, 11:00

We present J-HERTz (J-PLUS Heritage Exploration of Radio Targets at z < 5), a new multi-wavelength catalog combining optical narrow-band filter observations from the Javalambre Photometric Local Universe Survey (J-PLUS) with low-frequency radio data from the LOFAR Two-Metre SKy Survey (LoTSS), and infrared detections from WISE for 500,000 sources over 2100 deg² in the northern sky. The catalog...

13. Galaxies in Hydrogen Light: From Local Hα Maps to Distant Lyα Nebulae

Rahna Payyasseri (CEFCA)

02/10/2025, 11:15

Hydrogen emission lines provide powerful tracers of the gas that fuels star formation and shapes galaxy evolution. In this talk, I will present two complementary perspectives on galaxies in hydrogen light. First, I will discuss new J-PLUS Hα maps of nearby galaxies that reveal the distribution of ionized gas and ongoing star formation, offering insights into how feedback and environment...
