The Diffuse Light Envelope of Luminous Red Galaxies
The Diffuse Light Envelope of Luminous Red Galaxies
Abstract We use a stacking method to study the radial light profiles of luminous red galaxies (LRGs) at redshift ∼0.62 and ∼0.25, out to a radial range of 200 kpc. We do not find noticeable evolution of the profiles at the two redshifts. The LRG profiles appear to be well …
