Explore an in-depth lecture on radiation from accelerated charges, part of a summer course on astrophysics. Delve into topics such as plane waves, dipole approximation, energy flux, and radiation intensity. Examine the behavior of relativistic particles, synchrotron radiation, and gravitational waves. Learn about key theorems and concepts in astrophysical radiation, including quadrupole and magnetic dipole radiation, Landau levels, and synchrotron self-absorption. Gain insights into the diverse physical phenomena encountered in celestial objects, from solar wind to active galactic nuclei. Conclude with a preview of the next lecture on pulsars, supernova remnants, and radio galaxies, followed by a Q&A session.
