Sensitivity of Next-Generation CMB Surveys to Neutrinos and Other Light Relics
Cynthia Trendafilova, Srinivasan Raghunathan, Benjamin Wallisch +33
Neutrinos and other light relics leave characteristic imprints in the cosmic microwave background anisotropies, making their observation a sensitive probe of the particle content a…
Entropy plateaus can emerge from gas replacement at a characteristic halo mass in simulated groups and clusters of galaxies
Edoardo Altamura, Scott T. Kay, Joop Schaye +2
The evolution of the intergalactic medium (IGM) is influenced by gravitational collapse, radiative cooling, and baryonic feedback. Using cosmological hydrodynamic zoom-in simulatio…
Building models of the Universe with hydrodynamic simulations
Edoardo Altamura
Hydrodynamic simulations have become irreplaceable in modern cosmology for exploring complex systems and making predictions to steer future observations. In Chapter 1, we begin wit…
Inferring the dark matter splashback radius from cluster gas and observable profiles in the FLAMINGO simulations
Imogen Towler, Scott T. Kay, Joop Schaye +10
The splashback radius, coinciding with the minimum in the dark matter radial density gradient, is thought to be a universal definition of the edge of a dark matter halo. Observatio…
Galaxy cluster rotation revealed in the MACSIS simulations with the kinetic Sunyaev-Zeldovich effect
Edoardo Altamura, Scott T. Kay, Jens Chluba +1
The kinetic Sunyaev-Zeldovich (kSZ) effect has now become a clear target for ongoing and future studies of the cosmic microwave background (CMB) and cosmology. Aside from the bulk…
Gas clumping and its effect on hydrostatic bias in the MACSIS simulations
Imogen Towler, Scott Kay, Edoardo Altamura
We use the MACSIS hydrodynamical simulations to estimate the extent of gas clumping in the intracluster medium of massive galaxy clusters and how it affects the hydrostatic mass bi…
EAGLE-like simulation models do not solve the entropy core problem in groups and clusters of galaxies
Edoardo Altamura, Scott T. Kay, Richard G. Bower +5
Recent high-resolution cosmological hydrodynamic simulations run with a variety of codes systematically predict large amounts of entropy in the intra-cluster medium at low redshift…
