Abstract
The J-PAS survey will detect $\sim 10^4$ galaxies/deg$^2$ to produce a high-density 3D map of the Universe up to $z\sim 1$, employing an innovative approach with 56 narrow optical bands and the broad $i$ band.Observations finally started in 2023, and as of November/2024 we already have approximately 100 deg$^2$ imaged in all filters.The J-PAS Early Data Release is planned for November 22n…
