Cosmological Parameter Forecasts for a CMB-HD Survey

Amanda MacInnis, Neelima Sehgal, Miriam Rothermel

We present forecasts on cosmological parameters for a CMB-HD survey. For a $\Lambda$CDM + $N_{eff}$ + $\sum m_{\nu }$ model, we find $\sigma (n_s)=0.0013$ and $\sigma (N_{eff})=0.014$ using CMB and C…
