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…
Mass Proxy Quality of Halo Properties in IllustrisTNG and FLAMINGO Simulations: II. Galaxies, Stars, and Black Holes
Eddie Aljamal, August E. Evrard, Arya Farahi +1
We study the stellar, black hole, and satellite galaxy populations of group- and cluster-scale halos in the IllustrisTNG, TNG-Cluster, and FLAMINGO cosmological hydrodynamical simu…
The star-forming past and quenching of brightest cluster galaxies in TNG-Cluster
Sunna Gottschewski, Joey Braspenning, Annalisa Pillepich +2
The Brightest Cluster Galaxies (BCGs) in the most massive galaxy clusters of our Universe are, at present, mostly quiescent, elliptical, and red. However, their formation histories…
Inferring magnetic field strengths in high-redshift lensing galaxies from Faraday rotation measure observations
Stefan Reissl, Ralf S. Klessen, Annalisa Pillepich +3
Observations of Faraday rotation in the lensing galaxy of CLASS B1152+199 at z = 0.439 suggest that efficient dynamo mechanisms had already amplified galactic magnetic fields by th…
The host halo masses of AGNs and quasars at with TNG-Cluster, FLAMINGO and other cosmological galaxy simulations
Akanksha Kapahtia, Annalisa Pillepich, Joey Braspenning +5
Most observations and clustering analyses suggest that quasars inhabit a narrow range of dark-matter halo masses ( M) across cosmic time (). Recen…
Bulk vs. turbulent motions at the centres of galaxy clusters: AGN-driven turbulence according to TNG-Cluster
Bipradeep Saha, Annalisa Pillepich, Joey Braspenning +3
The highly dynamic intracluster medium (ICM) influences cluster thermodynamic evolution and probes key physical processes. Quantifying the non-thermal motions is therefore essentia…
