UltraVISTA is an Ultra Deep, near-infrared survey with the new VISTA surveys telescope of the European Southern Observatory (ESO). Over the course of 5 years, UltraVISTA will repeatedly image the COSMOS field in 5 bands resulting in three key surveys:

  • an ultra-deep broad-band (Y, J, H, Ks) survey (1408hr) covering 0.73 deg²
  • a deep broad-band (Y, J, H, Ks) survey (212hr) covering the full 1.5deg² field
  • a narrow-band (180hr) survey covering the same region as the ultra-deep broad-band survey.

  • NEW  Third data release (READY ! April 2016).
    newer  Second data release (Jan 2014).
     First data release (Feb 2012).
