The Planck Spectrum

• most awesomest example plotted
• basic properties
• Wein's displacement laws
• brightness/antenna temperature, e.g., as measured by Penzias & Wilson, and modern result (Mather+ 1994)

Thermal Radiation: Kirchhoff's Law

• thermal vs blackbody emitters
• example: Cas A X-ray spectrum

Imaging Summarized: Toolbox

Blackbody Radiation Summarized: Toolbox

• brightness temperature maps
• terrestrial example: AstroDog IR, optical; the Earth
• cosmic examples: the Moon, AGB star photosphere and wind the CMB

Scattering

• coherent isotropic scattering
• random walks
