Taylor, Astr 423 at UNM Course Goals To understand how radio astronomical instrumentation functions and is used in practice. To understand some of the exciting science carried out at radio wavelengths. To understand the astrophysical processes which give rise to radio emission A chance to see and work with real radio data from the Expanded Very Large Array, the Very Long Baseline Array, and the Long Wavelength Array 3 G. Taylor, Astr 423 at UNM Course Outline Exploring the Invisible Universe Some basic information (radiative transfer, thermal emission, electromagnetic waves) Signals and noise, receivers Antennas – Our Connection to the Universe The Two-Element Interferometer Aperture Synthesis techniques Connected element interferometers (EVLA) Very Long Baseline Interferometry (VLBA) Long Wavelength Interferometry (LWA) Synchrotron Emission and Magnetic Fields Active Galactic Nuclei and their Jets See the Syllabus for more details 4 G.
