Cosmologists working on Cosmic inflation are trying to constrain the parameter tensor to scalar ratio(r) which helps in putting tighter bounds on Inflation models. We use bandpower values calculated from BB power spectrum to estimate the tensor to scalar ratio 'r'. The estimation is done from the posteriors for 'r' created by simulation based inference(SBI) such as SNRE etc. to analyse the simulated data. Our aim is to check if SBI can analyse the CMB signal and ignore the dust and noise from the provided bandpower values used for training the neural network. |
