Rates of tidal disruption events from constrained cosmological simulations of the local Universe: population properties and implications for transient surveys
Julian S. Sommer, Ildar Khabibullin, Klaus Dolag +4
(abridged) Motivated by upcoming surveys like LSST, we estimate tidal disruption event (TDE) rates using the constrained cosmological Simulation of the LOcal Web (SLOW) to test the…
Constraining Effective Viscosity in the Intracluster Medium via the Thermal Sunyaev-Zeldovich Effect -- Predictions from the SLOW Constrained Coma Cluster Simulations
Frederick Groth, Yuan Li, Joseph Golec +4
We study the effect of viscosity on the Sunyaev-Zeldovich signal in a simulated constrained Coma cluster analog. We aim to provide alternative constraints on the amount of viscosit…
Simulating the LOcal Web (SLOW): VII. Intergalactic magnetic field models for multi-messenger applications
Johannes Stoiber, Klaus Dolag, Francesca Capel +4
Context. The propagation of ultra-high-energy cosmic rays (UHECRs) and ultra-high-energy gamma-rays remains an open question in astroparticle physics, with the intergalactic magnet…
Correcting the hydrostatic mass for non-thermal gas motions: a comparison of two approaches
Théo Lebeau, Nabila Aghanim, Jenny Sorce +1
An accurate estimation of the mass of galaxy clusters is key to precisely and unbiasedly constraining cosmological parameters through their number count. The hydrostatic mass, esti…
Gas motion in the intracluster medium of the Virgo cluster replica
Théo Lebeau, Stefano Ettori, Jenny G. Sorce +2
Within the deep gravitational potential of galaxy clusters lies the intracluster medium (ICM). At the first order, it is considered to be at hydrostatic equilibrium within the pote…
Cutting with precision -- Leveraging Collapse Volumes to generate the next generation of zoom-in initial conditions
Benjamin Seidel, Klaus Dolag, Jenny G. Sorce
Astrophysical processes happen across a wide range of scales. This poses a significant challenge from the perspective of modeling these processes. Modern cosmological simulations a…
