The BUFFALO Survey : The Subhalo Mass Function for Abell 2744 with Strong+Weak Gravitational Lensing
Nency R. Patel, Mathilde Jauzac, Anna Niemiec +16
We present a combined strong and weak gravitational lensing mass model of the massive merging galaxy cluster Abell 2744 (z = 0.308). The mass reconstruction combines strong-lensing…
Uncovering substructure with wavelets: proof of concept using Abell 2744
J. Schwinn, C. M. Baugh, M. Jauzac +2
A recent comparison of the massive galaxy cluster Abell 2744 with the Millennium XXL (MXXL) N-body simulation has hinted at a tension between the observed substructure distribution…
Analytic Derivation of the Halo Mass Function from the Non-Linear Cosmic Density Field
Laila Linke, Johannes Schwinn, Matthias Bartelmann
We estimate the halo mass function (HMF) by applying the excursion set approach to the non-linear cosmic density field. Thereby, we account for the non-Gaussianity of today's densi…
Growing a `Cosmic Beast': Observations and Simulations of MACS J0717.5+3745
M. Jauzac, D. Eckert, M. Schaller +18
We present a gravitational lensing and X-ray analysis of a massive galaxy cluster and its surroundings. The core of MACS\,J0717.5+3745 (\,$10^{15}…
Abell 2744: Too much substructure for Lambda CDM?
J. Schwinn, M. Jauzac, C. M. Baugh +5
The massive substructures found in Abell 2744 by Jauzac et al. (2016) present a challenge to the cold dark matter paradigm due to their number and proximity to the cluster centre.…
