Abstract:
space telescope, such as LiteBIRD, sation signal at on the tensor to scalar ratio. R such sensitivities signal is shrouded by emissions from our own galaxy, and spurious signals due to uncertainties in instrumental parameters. In the upcoming era of low signal/noise CMB analysis, it is critical to mitigate these biases to be able to reach the desired sensitivity. I talk about current efforts in modelling the astrophysical foregrounds and possible systematic effects, and the methods we use to extract out the underlying CMB signal.
