Brightest cluster galaxies: the centre can(not?) hold [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT We explore the persistence of the alignment of brightest cluster galaxies (BCGs) with their local environment. We find that a significant fraction of BCGs do not coincide with the centroid of the X-ray gas distribution and/or show peculiar velocities (they are not at rest with respect to the cluster mean).

Brightest cluster galaxies and the intracluster light

In this chapter, we delve into the formation and primary characteristics of two significant components within galaxy clusters: the brightest cluster galaxies (BCGs) and the intracluster light (ICL). Drawing upon recent and pertinent studies in the field, we explore the mechanisms driving their growth from high redshift to the present day, i.e., mergers

The Evolution of Brightest Cluster Galaxies

Astrophysics and Space Science, 2003
In this contribution we review the properties of Brightest Cluster Galaxies (BCGs) and discuss the impact that X-ray cluster selection is having on their use as cosmological probes. BCGs form a unique galaxy population. They are located near the gravitational centre of galaxy clusters and are the most massive galaxies in the universe, being some 10 ...

An Infrared Survey of Brightest Cluster Galaxies. II. Why are Some Brightest Cluster Galaxies Forming Stars? [PDF]

Astrophysical Journal, 2008
Quillen et al.(2007) presented an imaging survey with the {\it Spitzer Space Telescope} of 62 brightest cluster galaxies with optical line emission located in the cores of X-ray luminous clusters. They found that at least half of these sources have signs of excess infrared emission. Here we discuss the nature of the IR emission and its implications for

Brightest Members of Clusters of Galaxies

Nature, 1970
THE work of Humason, Mayall and Sandage1 and the more recent work of Sandage2–5 and Peterson6 show that the dispersion in the absolute magnitude of the first brightest galaxies in rich clusters of galaxies is only 0.3 magnitude. Peebles7 suggested that this small dispersion is simply the consequence of the cluster luminosity function and compared the ...
