J-PAS

J-PAS
Javalambre Physics of the Accelerating Universe Astrophysical Survey, J-PAS, is an unprecedented photometric sky survey of 8500 deg2 visible from Javalambre in 54 narrow and 2 intermediate photometric bands covering the entire optical spectrum in combination with 3 broad photometric bands. The 2.5m mirror of the JST250 telescope, combined with a 1.2 Giga-pixel camera containing an array of 14 CCDs, will produce high-quality images and a unique spectral resolution over the whole area of the survey, casting a new picture of the cosmos.

J-PLUS

J-PLUS

The Javalambre-Photometric Local Universe Survey, J-PLUS, is an unprecedented photometric sky survey of 8500 deg2 visible from Javalambre, using a set of 12 broad, intermediate and narrow band filters. J-PLUS will be a powerful 3D view of the nearby Universe that will observe and characterize tens of millions of galaxies and stars of the Milky Way halo, with a wide range of Astrophysical applications.

J-VAR

J-VAR

The Javalambre VARiablity survey (J-VAR) is a wide field photometric survey which uses non-photometric nights at OAJ and takes previous calibrated J-PLUS images as photometric reference. J-VAR observes 11 epochs with 7 filters (J0395, g, J0515, r, J0660, i, J0861) with T80Cam at JAST80. The cadence is defined by the weather conditions, with typical scales from minutes to months.

Mini-HAWKs

Mini-HAWKs

Mini-HAWKs is a ~50 sqr deg pathfinder of the Galactic Plane down to r~21 that uses 3 specially customized Hα filters that are optimized to select targets with broad Hα emission lines, formed in accretion discs around black holes (BHs). It will prove a novel photometric strategy that will eventually lead to the discovery of ~150 new Galactic accreting BHs i.e. a ten-fold increase over the known population. That will allow constraining the number density, orbital period distribution, kinematics and, ultimately, the BH mass spectrum. It will also uncover and characterize large numbers of other Hα emitting objects in the Galaxy to unprecedented depths, as well as, it will also furnish ~14h light curves of every object.
J-ALFIN

J-ALFIN

J-ALFIN, the Javalambre Assessment of Late stellar Feedback to the ISM by evolved Nebulae, will take advantage of the unprecedented field-of-view of the T80Cam at the JAST80 to map the large-scale emission of a carefully selected sample of Galactic nebulae around evolved stars. The late stages of dilution of planetary nebulae and nova remnants around low- and intermediate-mass stars, and Wolf-Rayet bubbles around massive stars, nebulae around supergiant B[e] stars and supernova remnants will be investigated in detail to assess the spatial extent and yields of different stars to the Interstellar Medium.
MUDEHaR

MUDEHaR

MUDEHaR (MUlti-epoch Disparity Examination of H-Alpha and infraRed) is a multi-epoch photometric survey in Hα and the calcium triplet window that uses T80Cam at the JAST80 telescope at Javalambre. It will obtain 100 epochs per field for 20 fields in the Galactic disk, each of two square degrees, for a total of 40 square degrees. Its main goal is to detect tens of thousands of variable Hα stars on a days-months-years scale, including massive stars with a magnetic field, pulsating stars, active M stars, and other types of variable stars. All data will be made available for public exploitation.
North-Phase

North-Phase

North-PHASE (Periodicity, Hot spots, Accretion Stability and Early evolution in young stellar clusters in the Northern Hemisphere) is a project led by the University of Dundee (UK) that "uses time to map space" to unveil the star-disk connection of young stars during the epochs of planet formation. The physical scales in the inner planet-forming disk and star are too small to be addressed by direct imaging, but time-resolved, multi-band photometric variability with broad- and narrow-band filters allows us to explore accretion, stellar spots and occultations by the innermost disk. Over 5 years, we can study how these change in timescales similar to inner planet orbits for thousands of young stars in clusters.

Alhambra

Alhambra
ALHAMBRA-survey is a photometric survey. The survey covers a total area of 4 square degrees in the sky distributed in 8 different fields (with half a degree per field) with 20 contiguous, equal width, medium band photometric filters from 3500 Å to 9700 Å, plus the standard broad bands JHKs in the Near Infrared.

Planck

Planck

The Planck satellite was launched on May 14th 2009 on a mission to measure the Cosmic Microwave Background (CMB) over the whole sky in finer detail and to a greater accuracy than has been possible before. This will allow us to measure the composition and evolution of the Universe better than ever before.
