Large Synoptic Survey Telescope White Paper; The Case for Matching U-band on Deep Drilling Fields


Abstract in English

U-band observations with the LSST have yet to be fully optimized in cadence. The straw man survey design is a simple coverage of the medium-deep-fast survey. Here we argue that deep coverage of the four deep drilling fields (XMM-LSS, ECDFS, ELAIS-S1 and COSMOS) has a much higher scientific return, given that these are also the target of the Southern Hemispheres Square Kilometer Array Pathfinder, the MeerKAT specifically, deep radio observations.
