Is there enough star formation in simulated protoclusters?
Seunghwan Lim, Douglas Scott, Arif Babul +5
As progenitors of the most massive objects, protoclusters are key to tracing the evolution and star-formation history of the Universe, and are responsible for per c…
Dynamical masses of brightest cluster galaxies II: constraints on the stellar IMF
S. I. Loubser, H. Hoekstra, A. Babul +2
We use stellar and dynamical mass profiles, combined with a stellar population analysis, of 32 brightest cluster galaxies (BCGs) at redshifts of 0.05 0.30, to place c…
LoCuSS: The splashback radius of massive galaxy clusters and its dependence on cluster merger history
Matteo Bianconi, Riccardo Buscicchio, Graham P. Smith +4
We present the direct detection of the splashback feature using the sample of massive galaxy clusters from the Local Cluster Substructure Survey (LoCuSS). This feature is clearly d…
Revisiting dynamical friction: the role of global modes and local wakes
Tomas Tamfal, Lucio Mayer, Thomas R. Quinn +4
The orbital decay of a perturber within a larger system plays a key role in the dynamics of many astrophysical systems -- from nuclear star clusters or globular clusters in galaxie…
Dynamical masses of brightest cluster galaxies I: stellar velocity anisotropy and mass-to-light ratios
S. I. Loubser, A. Babul, H. Hoekstra +3
We investigate the stellar and dynamical mass profiles in the centres of 25 brightest cluster galaxies (BCGs) at redshifts of 0.05 0.30. Our spectroscopy enables us t…
Optical and near-infrared observations of the SPT2349-56 proto-cluster core at z = 4.3
K. M. Rotermund, S. C. Chapman, K. A. Phadke +20
We present Gemini-S and {\it Spitzer}-IRAC optical-through-near-IR observations in the field of the SPT2349-56 proto-cluster at . We detect optical/IR counterparts for only…
