Cosmic Rays: Erratum

• radiocarbon production
• neutron monitors: hardware, data

Compton Scattering

Compton Emission

• cross section and energy transfer: ordinary kinematics
• inverse Compton power: single electron
• inverse Compton spectrum: single electron
• power-law electron spectra

Awesome Example: Active Galaxies--Blazars

• optical R-band imagse of PKS 0521-365 and RGB1532+302
• montage of 100 BL Lac objects
• AGN demographics (blazars part of 'other')
• blazar spectra, e.g., 3C66A
• unification cartoon
