The BAO-CMB Tension and Implications for Inflation
Elisa G. M. Ferreira, Evan McDonough, Lennart Balkenhol +3
The scalar spectral index is a powerful test of inflationary models. The tightest constraint on to date derives from the combination of cosmic microwave background (CMB…

Unified and consistent structure growth measurements from joint ACT, SPT and \textit{Planck} CMB lensing
Frank J. Qu, Fei Ge, W. L. Kimmy Wu +143
We present the tightest cosmic microwave background (CMB) lensing constraints to date on the growth of structure by combining CMB lensing measurements from the Atacama Cosmology Te…

What's the matter with ?
Gabriel P. Lynch, Lloyd Knox
Due to non-zero neutrino rest masses we expect the energy density today in non-relativistic matter, , to be greater than the sum of baryon and cold dark matter densities…
