As one of the nine ASKAP-supported survey science projects, DINGO directly addresses a key science goal of ASKAP: studying the evolution of HI from the current epoch to a time when the Universe was two-thirds is present age.
Measurements will be made of the evolution of key cosmological distributions and quantities including HI, the HI mass function, and the 2pt correlation function. Data from ASKAP will also be combined with that from the GAMA survey regions in a two-tiered strategy extending from redshift zero to ~0.4, providing a legacy dataset to enable a thorough study of the co-evolution of the stellar, baryonic, and dark matter content of galaxies.
Survey Design
The main DINGO survey will use 3200h to observe the GAMA G23 field (also part of WAVES deep) using two adjacent ASKAP pointings and two frequency ranges:
- DINGO Low-z: 2x800h fields, 0<z<0.1
- DINGO High-z: 2x800h fields, 0.25<z<0.4
