A rough guide to radio astronomy and its use in lensing studies. Simple stuff other lecturers may assume you know (and probably do). Basic Radio Information. Resolution. θ=λ/d Increase resolution by increasing d with interferometer arrays but loose surface brightness sensitivity.

Where Ae is the effective area of the telescope, Tsys is the system noise, B the receiver bandwidth and τ the integration time. The system noise comes from:
