An algorithm developed by researcher Andrés del Pino now applies Bayesian neural networks to data from the J-PLUS project. The aim is to robustly classify the astronomical objects detected by the survey and thus differentiate stars, quasars and galaxies. The research has been published in Astronomy and Astrophysics.

An article, led by CEFCA researcher Carlos López San Juan, focuses on those that are used for exoplanetary geology: white dwarfs with metals from the accretion of material from their planetary system. The research raises the contribution of the J-PLUS survey, developed from the Observatorio Astrofísico de Javalambre (OAJ), which now allows us to determine how the detection of these stars varies as they cool. The work has been published in Astronomy and Astrophysics.

The J-PLUS survey, carried out from the Observatorio Astrofísico de Javalambre, provides new data on 6,000 white dwarfs of the Milky Way

During the meeting, J-PLUS DR2, with almost twenty million objects, will be released to the international community

CEFCA, responsible for the construction and operation of the telescope and the instrumentation with which the survey is carried out, also leads the scientific production

The J-PLUS First Data Release amounts 1022 square degrees and includes scientific information of more than thirteen million of celestial objects, from asteroids to distant galaxies, including Milky Way stars.

CEFCA announces worldwide open access to the Early Data Release (EDR) of the Javalambre Photometric Local Universe Survey. This EDR consists of 18 J-PLUS pointings at different locations of the sky, observed in the twelve J-PLUS photometric optical bands, overall amounting to 36deg2. We provide access to the J-PLUS catalogues with photometric data in all the twelve bands for more than 400.000 astronomical objects, together with the actual FITS images and proper masks to avoid bright stars and other undesired areas.

After an intense period of fine tuning and optimization tasks developed by the OAJ/CEFCA Team, systematic observations with T80Cam@JAST80 have started. The telescope–camera system is in optimal performance, reaching normally seeing-limited images. So far, a best gaussian FWHM of 0.63”(+/-0.09”) over the 2deg² focal plane of T80Cam has been recorded.

The twelve filters of the J-PLUS survey have been integrated into T80Cam, the scientific camera which is installed in the JAST80 telescope of the Observatorio Astrofísico de Javalambre.
