Título: Blanco i-band Kilo-degree Survey - BlinK

Resumo: We propose to carry out BlinK: a 1000 sq-deg survey in the i-band with DECam down to magAB: 22.5. This data will enable us to study galaxy clusters, discover new strong lensing systems, study Lyman Break Analog Systems, find new star-forming early-type galaxies, study compact and fossil groups, in addition to carry out studies of large-scale structure and correlation with other wavelengths. Our kilo-degree field has not been previously explored in the i-band to the proposed depth nor with the DECam image quality and will benefit from existing spectroscopic data from SDSS and WiggleZ, and multi-wavelength data from other surveys, including existing DECam g,r,z data. This program builds up on the CFHT Stripe 82 (CS82) i-band survey and will be performed in close collaboration with the Blanco Imaging of the Southern Sky (BLISS) project and other DECam surveys. In addition to being a survey on its own, this proposal will have an impact on the current landscape of wide-field surveys, complementing the growing coverage of the extragalactic sky for dec < 30 deg. It can provide support to other surveys in the field, such as J-PLUS, and have a legacy value for targeting spectroscopic surveys or complementing the wavelength coverage of imaging surveys.
