The Javalambre-Photometric Local Universe Survey, J-PLUS (www.j-plus.es
), is defined to observe 8500 deg2
of the sky visible from the Observatorio Astrofísico de Javalambre (Teruel, Spain) with the panoramic camera T80Cam at the JAST/T80 telescope, using a set of 12 broad, intermediate and narrow band optical filters. Since J-PLUS is particularly designed to guarantee the photometric calibration of J-PAS (http://j-pas.org
), some J-PLUS filters are located at key stellar spectral features, allowing to retrieve very accurate spectral energy distributions (SEDs) for millions of stars and nearby galaxies. Apart from the g,r,i,z broad-band SDSS filters, J-PLUS includes a medium-band u filter (u_Javalambre) plus 7 narrow/medium-band filters located in [OII] λ3780Å, CaH+K λ3950Å, Hδ λ4100Å, the G-band λ4300Å, Mgb λ5150Å, Hα λ6600Å and the Ca triplet λ8610Å. With the above filter set, J-PLUS will provide SED information for every pixel of the sky, behaving in the end like a low resolution IFU of 8500deg2
with amazing capabilities in many areas of the Astrophysics. In particular, in this poster we present the most striking IFU-like science cases that J-PLUS is going to cover, like detailed 2D stellar population analysis (ages, metallicities, extinction and stellar mass) and star formation studies (reaching up to L_Hα ~1038
erg/s) for thousands of nearby galaxies, or the study of ages and metallicities for hundreds of extragalactic globular cluster systems down to the distance of the Virgo cluster, among many others.
