How Super-Quasars Shaped Early Galaxies and Confounded the JWST

Extremely powerful quasars in the early Universe drove star-forming gas out of their galaxies. These Super-quasars are behind the JWST's puzzling early Universe observations.

Cosmography alert 🚨

Jim Peebles strikes again on flat patterns in the cosmic structure, with an update of the evidence supporting an extended plane of de Vaucouleurs' Local Supercluster.

The Extended Plane of the Local Supercluster

An update of the evidence that radio galaxies and clusters of galaxies are more common than average near the plane of the de Vaucouleurs Local Supercluster shows that in the distance range 100 to 200Mpc objects whose positions are correlated with the plane of the Local Supercluster include galaxies that are exceptionally luminous at two microns, radio galaxies, and clusters of galaxies. There can be little doubt about this property of cosmic structure. I also argue for detection of this correlation for the galaxies at 400Mpc distance that are exceptionally luminous at two microns. It will be interesting to learn whether these results are expected in the standard cosmology.

This picture from the #JWST features an astounding number of #galaxies.

The objects in this frame span an incredible range of distances, from stars within our own Milky Way, marked by diffraction spikes, to galaxies billions of light-years away.
