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 approximated by a single Srsic profile, although some excess light can be seen outside 60 kpc. We quantify the excess light by measuring the integrated flux and find that the excess is about 10%—a non-dominant but still nonnegligible component.

发光红色星系的漫光包络

我们使用堆叠方法来研究红移 ∼0.62 和 ∼0.25 的红色发光星系 (LRG) 的径向光分布，径向范围为 200 kpc。我们没有发现两个红移处轮廓的明显演变。LRG 剖面似乎很好地近似于单个 Srsic 剖面，尽管在 60 kpc 之外可以看到一些多余的光。我们通过测量积分通量来量化多余的光，并发现多余的光量约为 10%——一个非主要但仍然不可忽略的分量。
