Abstract (from CDS):

Understanding the formation history of brightest cluster galaxies (BCGs) is an important topic in galaxy formation. Utilizing the Planck Sunyaev-Zel'dovich cluster catalogue, and applying the ansatz that the most massive haloes at one redshift remain among the most massive ones at a slightly later cosmic epoch, we have constructed cluster samples at redshift z ∼ 0.4 and z ∼ 0.2 that can be statistically regarded as progenitor-descendant pairs. This allows us to study the stellar mass assembly history of BCGs in these massive clusters at late times, finding that the degree of growth between the two epochs is likely at only few percent level, which is far lower compared to the prediction from a state-of-the-art semi-analytic galaxy formation model.
