Anomalies in Physical Cosmology

Just a quick note to mention that there’s an interesting review article on the arXiv by elder statesman of cosmology Jim Peebles with the abstract:

The ΛCDM cosmology passes demanding tests that establish it as a good approximation to reality. The theory is incomplete, of course, and open issues are being examined in active research programs. I offer a review of less widely discussed anomalies that might also point to hints to a still better cosmological theory if more closely examined.

Here is Figure 4 from the paper, which I’ve picked because it is pretty. It shows the distribution of bright (red) and faint (blue) galaxies within 9Mpc of the Milky Way.
