A formation mechanism for "Wrong Way" Radio Relics
Ludwig M. Böss, Ulrich P. Steinwandel, Klaus Dolag
Radio Relics are typically found to be arc-like regions of synchrotron emission in the outskirts of merging galaxy clusters, bowing out from the cluster center. In most cases they…
Exploring chemical enrichment of the intracluster medium with the Line Emission Mapper
François Mernier, Yuanyuan Su, Maxim Markevitch +27
Synthesized in the cores of stars and supernovae, most metals disperse over cosmic scales and are ultimately deposited well outside the gravitational potential of their host galaxi…
Mapping the Intracluster Medium in the Era of High-resolution X-ray Spectroscopy
Congyao Zhang, Irina Zhuravleva, Maxim Markevitch +24
High-resolution spectroscopy in soft X-rays will open a new window to map multiphase gas in galaxy clusters and probe physics of the intracluster medium (ICM), including chemical e…
Field-level simulation-based inference with galaxy catalogs: the impact of systematic effects
Natalí S. M. de Santi, Francisco Villaescusa-Navarro, L. Raul Abramo +11
It has been recently shown that a powerful way to constrain cosmological parameters from galaxy redshift surveys is to train graph neural networks to perform field-level likelihood…
Simulating the LOcal Web (SLOW) -- III: Synchrotron emission from the local cosmic web
Ludwig M. Böss, Klaus Dolag, Ulrich P. Steinwandel +4
Aims: Detecting diffuse synchrotron emission from the cosmic web is still a challenge for current radio telescopes. We aim to make predictions about the detectability of cosmic web…
Cosmological and idealized simulations of dark matter haloes with velocity-dependent, rare and frequent self-interactions
Moritz S. Fischer, Lenard Kasselmann, Marcus Brüggen +5
Dark matter self-interactions may have the capability to solve or at least mitigate small-scale problems of the cosmological standard model, Lambda Cold Dark Matter. There are a va…
