Radio Telescope Design Optimization Using Costing Constraints: Extrapolating LOFAR Costing to the Square Kilometre Array

The Square Kilometre Array: An International Project To Realize The World's Largest Radio Telescope

The Square Kilometre Array is one of the most complex science projects ever conceived. The scientific drivers are important questions about the evolution of the early Universe, fundamental physics, study of galaxies and stars across time, formation of exo-planetary systems and astrobiology. The scientific requirements such as sensitivity and resolution are so hard that the required technology a...

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...

Memo 97 The Square Kilometre Array as a Radio Synoptic Survey Telescope: Widefield Surveys for Transients, Pulsars and ETI

This document explores some of the issues involved in searching for transients, pulsars, and ETI signals with a widefield instrument. We assume also that steady sources are surveyed at the same time, including spectral lines and continuum radiation from galaxies and AGNs. We present a survey metric that quantifies survey completeness and incorporates time-variable sources with arbitrary duratio...
