Measuring the scalar induced gravitational waves from observations
Jun Li, Guang-Hai Guo
We measure the scalar induced gravitational waves from the cosmic microwave background (CMB) observations and the gravitational wave observations. In the CDM+ model, we const…

Measuring the spectral running from cosmic microwave background and primordial black holes
Jun Li, Qing-Guo Huang
We constrain the spectral running by combining cosmic microwave background (CMB) data, baryon acoustic oscillation (BAO) data and the constraint from primordial black holes (PBHs).…
