Molecular gas in CLASH brightest cluster galaxies at z ∼ 0.2 – 0.9 [PDF]
Astronomy & Astrophysics, 2020 Brightest cluster galaxies (BCGs) are excellent laboratories for the study of galaxy evolution in dense Mpc-scale environments. We used the IRAM-30 m to observe, in CO(1→0), CO(2→1), CO(3→2), or CO(4→3), 18 BCGs at z ∼ 0.2 − 0.9 drawn from the Cluster ...

Atmospheric Pressure and Molecular Cloud Formation in Early-type Galaxies
The Astrophysical Journal, 2023 A strong correlation between atmospheric pressure and molecular gas mass is found in central cluster galaxies and early-type galaxies. This trend and a similar trend with atmospheric gas density would naturally arise if the molecular clouds condensed ...

Intrinsic Shapes of Brightest Cluster Galaxies
The Astrophysical Journal, 2022 Abstract We discuss the statistical distribution of galaxy shapes and viewing angles under the assumption of triaxiality by deprojecting observed surface brightness profiles of 56 brightest cluster galaxies (BCGs) coming from a recently published large deep-photometry sample.

The hierarchical formation of the brightest cluster galaxies [PDF]
, 2006 We use semi-analytic techniques to study the formation and evolution of brightest cluster galaxies (BCGs). We show the extreme hierarchical nature of these objects and discuss the limitations of simple ways to capture their evolution.

Structure of Brightest Cluster Galaxies and Intracluster Light [PDF]
Astrophysical Journal Supplement Series, 2019 Observations of 170 local (z ≲ 0.08) galaxy clusters in the northern hemisphere have been obtained with the Wendelstein Telescope Wide Field Imager (WWFI).

Constraining cold accretion on to supermassive black holes: molecular gas in the cores of eight brightest cluster galaxies revealed by joint CO and CN absorption [PDF]
Monthly notices of the Royal Astronomical Society, 2019 To advance our understanding of the fuelling and feedback processes which power the Universe’s most massive black holes, we require a significant increase in our knowledge of the molecular gas which exists in their immediate surroundings.

The Angular Momentum of Brightest Cluster Galaxies [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractMassive Brightest Cluster Galaxies (BCGs) are observed to have a range of angular momenta, suggesting a variety of merging histories.

The growth of brightest cluster galaxies and intracluster light over the past 10 billion years [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We constrain the evolution of the brightest cluster galaxy plus intracluster light (BCG + ICL) using an ensemble of 42 galaxy groups and clusters that span redshifts of z = 0.05−1.75 and masses of M500,c= 2 × 1013−1015 M⊙.
