The VOICE Survey : A VST Deep & Wide Extragalactic Survey

The VST Optical Imaging of the CDFS and ES1 (VOICE) Survey is an Optical Imaging Survey using the VLT Survey Telescope (VST) of the European Southern Observatory (ESO) to obtain Deep & Wide Optical Imaging of two Extragalactic Southern Sky Regions.

Together with its Supernova Diversity And Rate Evolution (SUDARE) sister project, VOICE covers 8 square degrees evently split between two sky areas known as the CDFS and the ES1 fields in 4 (ugri) optical bands down to AB~26 limiting magnitude. The footprint will fully overlap with the VISTA-VIDEO, Spitzer-SERVS, Herschel-HerMES and ATCA-ATLAS surveys of the same fields.

A presentation describing the project is available here while a paper presenting the survey (Vaccari et al. 2016, PoS, 275, 26) is available here. Observations of the CDFS field started in 2011 and were completed in 2017. Observations of the ES1 field are ongoing, and previous BVR observations of the same field obtained as part of the ESIS survey have been reprocessed. Science papers based on the SUDARE/VOICE dataset are listed here

The survey is jointly led by Giovanni Covone (Naples, Italy) & Mattia Vaccari (Cape Town, South Africa). Please get in touch if you need any further information!

The VOICE collaboration between Italy and South Africa is supported by the Italian Ministry of Foreign Affairs and International Cooperation (MAECI) and the South African National Research Foundation (NRF).
