The total mass of a galaxy cluster is one of its most fundamental properties. Together with
the redshift, the mass links observation and theory, allowing us to use the cluster population …

Formation of galaxy clusters corresponds to the collapse of the largest gravitationally bound
overdensities in the initial density field and is accompanied by the most energetic …

We present a joint shear-and-magnification weak-lensing analysis of a sample of 16 X-ray-
regular and 4 high-magnification galaxy clusters at 0.19≲ z≲ 0.69 selected from the Cluster …

We study the bias and scatter in mass measurements of galaxy clusters resulting from fitting
a spherically symmetric Navarro, Frenk, & White model to the reduced tangential shear …

The utility of large Sunyaev–Zel'dovich (SZ) surveys for determining cosmological
parameters from cluster abundances is limited by the theoretical uncertainties in the …

We study the mass distribution of a sample of 28 galaxy clusters using strong and weak
lensing observations. The clusters are selected via their strong lensing properties as part of …

We present bahamas-SIDM, the first large-volume,, cosmological simulations including both
self-interacting dark matter (SIDM) and baryonic physics. These simulations are important for …

We present a comparison between weak-lensing and x-ray mass estimates of a sample of
numerically simulated clusters. The sample consists of the 20 most massive objects at …

We use the high-resolution cosmological N-body simulations from the Aquarius project to
investigate in detail the mechanisms that determine the shape of Milky Way type dark matter …

Several extensions of the standard cosmological model include scalar fields as new
degrees of freedom in the underlying gravitational theory. A particular class of these scalar …
