Due to maintenance, on Saturday 10th and on Wednesday 14th June there could be intermittent outages on the site and services throughout all the day. We are sorry for the inconvenience.
The Catalogues Portal of the Centro de Estudios de Física del Cosmos de Aragón (CEFCA) provides access to data of the large astronomical surveys catalogues carried out in the Observatorio Astrofísico de Javalambre (OAJ). This portal provides data visualization and download through several different online tools, each suited to a particular need, and services based on the virtual observatory (VO) protocols.
The Observatorio Astrofísico de Javalambre (OAJ) is a Spanish astronomical ICTS (Infraestructura Científica y Técnica Singular) located at the Sierra de Javalambre in Teruel, Spain, particularly conceived and constructed for carrying out large sky astronomical surveys. The OAJ mainly consists of two professional telescopes with large fields of view (FoV) and seeing-limited image quality all over their entire FoVs: the 2.5m Javalambre Survey Telescope (JST250), a large-etendue telescope with a FoV of 3 deg diameter, and the 80cm Javalambre Auxiliary Survey Telescope (JAST80), with a FoV of 2deg. Both telescopes are equipped with panoramic cameras, state-of-the-art, large format CCDs and unique sets of optical filters suited to survey the Universe in an unprecedented way all over the optical spectral range.
OAJ is mostly devoted to conduct two unprecedented large sky multi-filter surveys: Javalambre-Photometric Local Universe Survey (J-PLUS) and Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS). They will cover 8500 deg2 of the sky visible from Javalambre using a set of broad, intermediate and narrow band optical filters providing powerful 3D views of the Universe. J-PLUS is being carried out using the JAST80 telescope and T80Cam instrument using a set of 12 filters and J-PAS is going to be carried out using JST250 telescope and JPCam instrument using a set of 59 filters.
