Development of Calibration Strategies for the Simons Observatory

Understand

The Simons Observatory (SO) is a set of cosmic microwave background instruments that will be deployed in the Atacama Desert in Chile.

• The key science goals include setting new constraints on cosmic inflation, measuring large scale structure with gravitational lensing, and constraining neutrino masses.
• Meeting these science goals with SO requires high sensitivity and improved calibration techniques.
• In this paper, we highlight a few of the most important instrument calibrations, including spectral response, gain stability, and polarization angle calibrations.
