Artificial intelligence is incorporated into the classification of stars, quasars and galaxies through the J-PLUS project.
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.

The J-PLUS project helps to understand key properties of metal-polluted white dwarf stars.

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.

Work of dismantling the telescope JAST80 ( Bamberg , Germany )
The arrival of the telescope to the Pico del Buitre involves starting the night activities of the Observatorio Astrofísico de Javalambre (CEFCA's observatory). This is one of the most important milestones of the project.

JAST80 undergoes first factory tests

Last February, the factory integration phase of the JAST80 telescope of the Observatorio Astrofísico de Javalambre (CEFCA) was completed. The telescope is assembled at Bamberg (Germany) where it is currently being tested with dummy optics. Preliminary tests show that the telescope can move with a velocity of up to 40 degrees per second, which makes T80 one of the worldwide fastest telescopes.
