J-PAS (Javalambre Physics of the Accelerating universe Astrophysical Survey) is an astronomical survey^[1] is being carried out by the Astrophysical Observatory of Javalambre (OAJ), located in Pico del Buitre in Sierra de Javalambre, in Teruel, Spain. J-PAS officially started in the summer of 2023.^[2]

OAJ is managed by Aragon Center for Physics of the Cosmos (CEFCA) and consists of two telescopes: a 2.5-metre primary mirror telescope (JST/T250) and an 80-centimeter telescope (JAST/T80). J-PAS is surveying the sky with JST/T250 telescope which has a 1.2 Giga-pixel camera, constituted by an array of 14 CCDs. J-PAS will observe more than 8000 square degrees (about 1/5 of the whole sky) in 57 filters during 5 to 6 years.

J-PAS filters cover the entire visible region of the electromagnetic spectrum (3500 Å to 10000 Å)^[3] and can be classified as:

54 narrow-band (roughly 14-nanometer width) filters.
2 medium-band (roughly 50-nanometer width) filters; these are located on the extreme blue and extreme red of the spectral coverage of J-PAS filters.
1 broad-band iSDSS (roughly 200-nanometer width) filter; which is also used as the detection filter.

History and members

J-PAS was one of the founding ideas behind OAJ, see OAJ history for more. The founding institutes of J-PAS are listed below.

Centro de Estudios de Fisica del Cosmos de Aragon, in Teruel, Spain.
Brazilian National Observatory, Rio de Janeiro, Brasil.
Instituto de Astronomia, Geofísica e Ciências Atmosféricas da Universidade de São Paulo [pt], in São Paulo, Brazil.
Instituto de Astrofísica de Andalucía-CSIC, in Granada, Spain.

Full J-PAS members are from the founding institutes above; although scientists from other institutes can also apply to become associate members or external collaborators.
