On the mass mismatch between simulations and weak-lensing measurements
Jacob Svensmark, Davide Martizzi, Adriano Agnello
The recently discovered discrepancy between galaxy mass measurements from weak lensing and predictions from abundance matching questions our understanding of cosmology, or of the g…
Estimating the dark matter velocity anisotropy to the cluster edge
Jacob Svensmark, Steen H. Hansen, Davide Martizzi +2
Dark matter dominates the properties of large cosmological structures such as galaxy clusters, and the mass profiles of the dark matter have been measured for these equilibrated st…
Baryons in the CosmicWeb of IllustrisTNG - I: Gas in Knots, Filaments, Sheets and Voids
Davide Martizzi, Mark Vogelsberger, Maria Celeste Artale +9
We analyze the IllustrisTNG simulations to study the mass, volume fraction and phase distribution of gaseous baryons embedded in the knots, filaments, sheets and voids of the Cosmi…
Sub-structure and merger detection in resolved NIKA Sunyaev-Zel'dovich images of distant clusters
R. Adam, O. Hahn, F. Ruppin +48
Sub-structures in the hot gas of galaxy clusters are related to their formation history and to the astrophysical processes at play in the intracluster medium (ICM). The thermal Sun…
Infall near clusters of galaxies: comparing gas and dark matter velocity profiles
L. Albaek, S. H. Hansen, D. Martizzi +2
We consider the dynamics in and near galaxy clusters. Gas, dark matter and galaxies are presently falling into the clusters between approximately 1 and 5 virial radii. At very larg…
Mass modeling of galaxy clusters: quantifying hydrostatic bias and contribution from non-thermal pressure
Davide Martizzi, Harrison Agrusa
Galaxy cluster mass determinations achieved using X-ray and Sunyaev-Zel'dovich data combined with the assumption of hydrostatic equilibrium are generally biased. The bias exists fo…
