The suppression of the matter power spectrum: strong feedback from X-ray gas mass fractions, kSZ effect profiles, and galaxy-galaxy lensing
Jared Siegel, Leah Bigwood, Alexandra Amon +6
Baryon feedback redistributes gas relative to the underlying dark matter distribution and suppresses the matter power spectrum on small scales, but the amplitude and scale dependen…
Self-consistent secondary cosmic microwave background anisotropies and extragalactic foregrounds in the FLAMINGO simulations
Tianyi Yang, Ian G. McCarthy, Fiona McCarthy +6
Secondary anisotropies in the cosmic microwave background (CMB) contain information that can be used to test both cosmological models and models of galaxy formation. Starting from…
The kinetic Sunyaev Zeldovich effect as a benchmark for AGN feedback models in hydrodynamical simulations: insights from DESI + ACT
Leah Bigwood, Masaya Yamamoto, Jared Siegel +7
Baryonic feedback remains one of the largest uncertainties in cosmological hydrodynamical simulations, with different prescriptions producing divergent predictions for the fraction…
FLAMINGO: Tracing the co-evolution of hot gas and black holes in galaxy groups and clusters
Emily E. Costello, Ian G. McCarthy, Jaime Salcido +4
The gas mass fraction of galaxy groups and clusters is a key physical quantity for constraining the impact of feedback processes on large-scale structure. While several modern cosm…
Joint X-ray, kinetic Sunyaev-Zeldovich, and weak lensing measurements: toward a consensus picture of efficient gas expulsion from groups and clusters
Jared Siegel, Alexandra Amon, Ian G. McCarthy +7
There is no consensus on how baryon feedback shapes the underlying matter distribution from either simulations or observations. We confront the uncertain landscape by jointly analy…
The impact of galaxy bias on cross-correlation tomography
Sara Maleubre, Matteo Zennaro, David Alonso +3
The cross-correlation of galaxies at different redshifts with other tracers of the large-scale structure can be used to reconstruct the cosmic mean of key physical quantities, and…
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…
