Spectral Distortion Fisher Forecasting

CMB Signals

• Blackbody CMB
• Thermal SZ ("y") + relativistic effects
• mu distortion
• r-type ("residual", or non-mu/non-y) distortion
• H and He recombination lines

Foregrounds

• Cosmic Infrared Background (dusty galaxies)
• Galactic dust
• Galactic synchrotron
• Extragalactic synchrotron/radio emission
• Galactic "anomalous microwave emission" (perhaps spinning dust)
• Galactic free-free emission
• CO lines
