When considering cosmic rays, astronomers usually think of the interesting fields of study where the cosmic ray flux from outside of the galaxy is predicted. Unfortunately for Cosmologists, cosmic rays (CR) produce well-known and unwanted systematic effects.
This talk begins with a light overview of the state of Cosmology missions in space, and the history of the battle against CR effects. From this we move on to the preparation for the next-generation Cosmic Microwave Background (CMB) space mission LiteBIRD, whose ambitious science goal requires unprecedented sensitivity and complete control over all systematic effects.
We describe our progress on evaluating CR effects in the low and high frequency instruments, as well as our plan for improving the outcomes in the future.
