~0.5 million fibre hours
Design accurate as of August 2015
The WAVES-UltraDeep survey design is fluid and will likely cover 3-6 deep fields each with a single 2deg2 pointing, targeting an i-band magnitude limited sample (currently imag <~ 22.3, assuming 6 fields, giving ~80k sources per field). The survey will probe faint galaxy populations to z~1.5 and likely be matched to MOONS and proposed SKA-mid survey fields to maximise science return.
WAVES-UltraDeep will be similar in depth to zCOSMOS-bright, but cover ~6-12 times the area and have >95% completeness, allowing a detailed study of galaxy evolution and structure formation over the last 9.5 billion years. WAVES-UltraDeep will target well-studied deep fields with existing multi-wavelength datasets, which are accessible to the 4MOST site. Possible field positions are:
