  5. Main Science Goals • Double the total number of radio sources known • Constrain evolution of radio-loud AGN population

  6. Main Science Goals • Double the total number of radio sources known • Constrain evolution of radio-loud AGN population Mao et al. 2012

  7. Main Science Goals • Double the total number of radio sources known • Constrain evolution of radio-loud AGN population • Increase the total number of sub-mJy radio sources by two orders of magnitude • Constrain star formation to z~0.5

  8. Main Science Goals • Double the total number of radio sources known • Constrain evolution of radio-loud AGN population • Increase the total number of sub-mJy radio sources by an order of magnitude • Constrain star formation to z~0.5

  9. Main Science Goals • Double the total number of radio sources known • Constrain evolution of radio-loud AGN population • Increase the total number of sub-mJy radio sources by an order of magnitude • Constrain star formation to z~0.5

  10. Compliment full EMU • Cover full 700-1800MHz frequency range • Switch between 3 bands every 20mins • Obtain spectral index and spectral curvature information

  11. Compliment full EMU • Cover full 700-1800MHz frequency range • Switch between 3 bands every 20mins • Obtain spectral index and spectral curvature information • Characterise faint population • Obtain unique samples of rare sources: USS, GPS • Allow spectral index and curvature to be compared to full EMU determined over narrower range • Obtain polarisation and RM measurements which are very important in diagnosis of faint populations

  12. Additional EMU Science • Cosmology • Galactic Astronomy • Local Galaxies • Serendipitous discoveries Additional ASKAP Science • The polarised sky • HI absorption • Transients • Legacy value to astronomical community

  13. Discussion points • Can the correlator be adapted to 384MHz (or =>366MHz) ? • Angular resolution is key: confusion and cross-identification • Can the full bandwidth be imaged simultaneously? • Which areas of sky would be prioritised? • Deep survey expected by combining regular observations of standard field (as part of science verification).
