Tuesday

Key to harnessing the power of the Rubin deep imaging and transient surveys will be utilising the wealth of multiwavelength data available on Rubin survey fields. The VIRCAM camera on the VISTA telescope in particular spans the vital near infrared ZYJHKs bands with a range of public surveys covering well-studied deep extragalactic fields (e.g. XMM-LSS, COSMOS) down to unprecedented depths as well as providing shallower coverage over the entire Southern hemisphere. The near infra-red bands are vital for constraining the stellar masses of galaxies, discovering high-redshift and dust-obscured galaxies and AGN and improving photometric redshift estimates. We have produced a test combined optical and NIR data set using the LSST Science Pipelines and the currently available Hyper Suprime Cam Public Data Release 2 processed together with three VISTA Public imaging surveys - VHS, VIKING and VIDEO. This talk will present these prototype data sets and initial applications and discuss further developments that we will implement prior to the start of Rubin observations. Examples of the utility of the data to extragalactic astronomy will be given alongside plans for early science with Rubin and VISTA combined data. Finally lessons learnt from VISTA integration will be discussed alongside possibilities for further extensions to other instruments and telescopes.
