Matter power spectrum: from Ly$\alpha$ forest to CMB scales
  We present a new compilation of inferences of the linear 3D matter power
spectrum at redshift $z\,{=}\,0$ from a variety of probes spanning several
orders of magnitude in physical scale and in cosmic history. We develop a new
lower-noise method for performing this inference from the latest Ly$\alpha$
forest 1D power spectrum data. We also include cosmic microwave background
(CMB) temperature and polarization power spectra and lensing reconstruction
data, the cosmic shear two-point correlation function, and the clustering of
luminous red galaxies. We provide a Dockerized Jupyter notebook housing the
fairly complex dependencies for producing the plot of these data, with the hope
that groups in the future can help add to it. Overall, we find qualitative
agreement between the independent measurements considered here and the standard
$\Lambda$CDM cosmological model fit to the {\it Planck} data
