TNGC-SIDM I: Evolution of massive cluster mergers under the self-interacting dark matter paradigm
Wonki Lee, Dylan Nelson, Myungkook J. Jee +8
Merging galaxy clusters provide an ideal laboratory for testing the self-interacting nature of dark matter. In this paper, we present a pilot study of magnetohydrodynamical cosmolo…
The origin of scatter in the X-ray luminosity - halo mass relation of galaxy clusters
Joey Braspenning, Joop Schaye, Annalisa Pillepich +1
Galaxy groups and clusters are excellent probes of large-scale structure and are shaped by some of the most energetic physical processes in the Universe. They follow a tight scalin…
Introducing the AIDA-TNG project: galaxy formation in alternative dark matter models
Giulia Despali, Lauro Moscardini, Dylan Nelson +3
We introduce the AIDA-TNG project, a suite of cosmological magnetohydrodynamic simulations that simultaneously model galaxy formation and different variations of the underlying dar…
Calibrating cosmological simulations with implicit likelihood inference using galaxy growth observables
Yongseok Jo, Shy Genel, Benjamin Wandelt +7
In a novel approach employing implicit likelihood inference (ILI), also known as likelihood-free inference, we calibrate the parameters of cosmological hydrodynamic simulations aga…
Unifying Sunyaev-Zel'dovich and X-ray predictions from clusters to galaxy groups: the impact of X-ray mass estimates on the scaling relation
Ana-Roxana Pop, Lars Hernquist, Daisuke Nagai +7
One of the main limitations in precision cluster cosmology arises from systematic errors and uncertainties in estimating cluster masses. Using the Mock-X pipeline, we produce synth…
Magnetization of the intergalactic medium in the IllustrisTNG simulations: the importance of extended, outflow-driven bubbles
Andres Aramburo Garcia, Kyrylo Bondarenko, Alexey Boyarsky +3
We study the effects of galaxy formation physics on the magnetization of the intergalactic medium (IGM) using the IllustrisTNG simulations. We demonstrate that large-scale regions…
