Effects of boosting on extragalactic components: methods and statistical studies
William R. Coulton, Sydney Feldman, Karime Maamari +3
In this work we examine the impact of our motion with respect to the CMB rest frame on statistics of CMB maps by examining the one-, two-, three- and four- point statistics of simu…
Satellite galaxy abundance dependency on cosmology in Magneticum simulations
Antonio Ragagnin, Alessandra Fumagalli, Tiago Castro +4
Context: Modelling satellite galaxy abundance in Galaxy Clusters (GCs) is a key element in modelling the Halo Occupation Distribution (HOD), which itself is a powerful tool t…
Galaxy Velocity Bias in Cosmological Simulations: Towards Percent-level Calibration
Dhayaa Anbajagane, Han Aung, August E. Evrard +8
Galaxy cluster masses, rich with cosmological information, can be estimated from internal dark matter (DM) velocity dispersions, which in turn can be observationally inferred from…
Unequal-mass mergers of dark matter haloes with rare and frequent self-interactions
Moritz S. Fischer, Marcus Brüggen, Kai Schmidt-Hoberg +3
Dark matter (DM) self-interactions have been proposed to solve problems on small length scales within the standard cold DM cosmology. Here, we investigate the effects of DM self-in…
Velocity dispersion of the brightest cluster galaxies in cosmological simulations
I. Marini, S. Borgani, A. Saro +7
Using the DIANOGA hydrodynamical zoom-in simulation set of galaxy clusters, we analyze the dynamics traced by stars belonging to the Brightest Cluster Galaxies (BCGs) and their sur…
Exploring the role of cosmological shock waves in the Dianoga simulations of galaxy clusters
Susana Planelles, Stefano Borgani, Vicent Quilis +6
Cosmological shock waves are ubiquitous to cosmic structure formation and evolution. As a consequence, they play a major role in the energy distribution and thermalization of the i…
