J-PAS experiment

​The J-PAS experiment (Javalambre Physics of the Accelerating Universe Astrophysical Survey) is a Spanish-Brazilian collaboration that aims to survey around 90 million galaxies, up to redshift 1.3, covering 8000 sq. degrees. In addition, it is able to detect millions of QSOs and several thousands of supernovae. Thanks to all this, J-PAS is a key experiment to characterize the equation-of-state of the dark energy and, therefore, to better understand the physics of the accelerated expansion of the universe. Besides this major objective, J-PAS is a tremendous support for cosmology, since it also provide us with very important information about dark matter and the physics of cosmic inflation.
