Red-sequence early-type galaxies in clusters

It is not well understood whether the growth of early-type cluster galaxies proceeds inside-out, outside-in, or at the same pace at all radii. In this work we measured the...

目前学界尚未明确星系团中的早型星系（early-type cluster galaxies）的增长究竟是由内向外、由外向内，还是在所有半径处以相同速率进行。在本项研究中，我们对……进行了测量。
