End-to-end compute model of the Square Kilometre Array

Scientific requirements for next-generation radio telescopes significantly influence compute requirements of their processing facilities. For future instruments, such as the Square Kilometre Array, seemingly minor changes can easily push compute requirements into the exascale domain. We present a model for engineers and astronomers to understand these relations and to make trade-offs in radio t...

Extragalactic radio surveys in the pre-Square Kilometre Array era

The era of the Square Kilometre Array is almost upon us, and pathfinder telescopes are already in operation. This brief review summarizes our current knowledge of extragalactic radio sources, accumulated through six decades of continuum surveys at the low-frequency end of the electromagnetic spectrum and the extensive complementary observations at other wavelengths necessary to gain this unders...

Meeting the Calibration Requirements for the Square Kilometre Array

Calibration of the Square Kilometre Array (SKA) will be the key to successfully achieving an astronomical instrument two orders of magnitude better than existing radio telescopes. The extent to how accurate the calibration data should be is dependent on the sensitivity of the processing algorithm to errors, or its robustness. The SKA telescope calibration data will be sensitive to many factors,...
