The farthest quasars (IMAGE)
Caption
The vertical axis shows the mass of dark matter halos surrounding quasars, galaxies with active cores. The horizontal axis shows the age of the universe with the present on the left. Given so many properties of the universe change on these time scales, it’s surprising that the DMH mass corresponding to a quasar has remained stable.
