Description:
The VMC survey aims to obtain YJKs band photometry across the system down to Ks=20.3 at S/N=10. This sensitivity corresponds to the bottom of the red giant branch field stellar population and allows us to determine the global spatially resolved star formation history with unprecedented quality and to construct a three-dimensional map of the system. A wide-area encompassing the D25 as well as major features delineated by the distribution of stars and HI gas, will both trace the structure of the galaxies and signatures of past and present interactions. Contemporary optical and kinematic observations of comparable sensitivity will provide the community with a superior database for future studies of the system and will give us an excellent insight as to what has happened elsewhere in the Universe.

Description:
The VVV survey will perform wide FOV multi-epoch observations of the Galaxy's bulge and part of the disk, providing the astronomical public community with a high resolution 3-D (or 4-D if you include the time dimension) map of the bulge.

Description:
NASA's Wide-field Infrared Survey Explorer (WISE; Wright et al. 2010) mapped the sky at 3.4, 4.6, 12, and 22 μm (W1, W2, W3, W4) in 2010 with an angular resolution of 6.1", 6.4", 6.5", & 12.0" in the four bands. WISE achieved 5Ï? point source sensitivities better than 0.08, 0.11, 1 and 6 mJy in unconfused regions on the ecliptic in the four bands. Sensitivity improves toward the ecliptic poles due to denser coverage and lower zodiacal background.
The zCOSMOS redshift survey used 600h on the VIMOS spectrograph spread over
five observing seasons (2005-2009) to obtain spectra of about 20,000 galaxies
selected to have Iab < 22.5 across the full 1.7 deg2 of the COSMOS field.
This part, "zCOSMOS-bright", was designed to yield a high and fairly uniform
sampling rate (about 70%), with a high success rate in measuring redshifts
(approaching 100% at 0.5 < z < 0.8), and with sufficient
velocity accuracy
(about 100 km/s) to efficiently map the environments of galaxies down to the
scale of galaxy groups out to redshifts z ~ 1.
