Descripción
J-PAS is a Spanish-Brazilian 8500 deg^2 Cosmological Survey which will
be carried out from the Javalambre Observatory with a purpose-built,
dedicated 2.5 m telescope and a 4.7 deg^2 camera with 1.2 Gpix. Starting
in 2015, J-PAS will use 59 filters to measure high precision 0.003(1+z)
photometric redshifts for 90M galaxies plus several million QSOs, about
50 times more than the largest current spectroscopic survey, sampling an
effective volume of ˜ 14 Gpc^3 up to z=1.3. J-PAS will not only be
first radial BAO experiment to reach Stage IV; it will also detect and
measure the mass of 7× 10^5 galaxy clusters and groups, setting
constrains on Dark Energy which rival those obtained from BAO
measurements. The combination of a set of 145 Å NB filters, placed
100 Å apart, and a multi-degree field of view is a powerful
``redshift machine'', equivalent to a 4000 multiplexing spectrograph,
but many times cheaper to build. The J-PAS camera is equivalent to a
very large, 4.7 deg^2 ``IFU'', which will produce a time-resolved, 3D
image of the Northern Sky with a very wide range of scientific
applications in Galaxy Evolution, Stellar Physics and the Solar System.
