Unifying cluster and galaxy cosmology analyses using the galaxy-halo connection
Shulei Cao, Hao-Yi Wu, Andrés N. Salcedo +3
Galaxies and galaxy clusters trace the same cosmic density field, but their statistics have been modeled separately in cosmological analyses. We present a unified, simulation-based…
Cosmological back-reaction of baryons on dark matter in the CAMELS simulations
Matthew Gebhardt, Daniel Anglés-Alcázar, Shy Genel +13
Baryonic processes such as radiative cooling and feedback from massive stars and active galactic nuclei (AGN) directly redistribute baryons in the Universe but also indirectly redi…
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…
Inferring the Impacts of Baryonic Feedback from Kinetic Sunyaev-Zeldovich Cross-Correlations
Alex Laguë, Mathew S. Madhavacheril, Josh Borrow +4
The complex processes of baryonic feedback associated with galaxy evolution are still poorly understood, and their impact on the clustering of matter on small scales remains diffic…
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: Baryonic effects on the weak lensing scattering transform
Mariia Marinichenko, Marcel P. van Daalen, Elena Sellentin +3
The scattering transform is a wavelet-based statistic capable of capturing non-Gaussian features in weak lensing (WL) convergence maps and has been proven to tighten cosmological p…
Luminosity-Dependent Assembly Bias of Central Galaxies from Weak Lensing and Clustering
Zhenjie Liu, Hironao Miyatake, Joop Schaye +3
Assembly bias, which is the variation in halo clustering at fixed mass driven by formation history, has long been predicted by numerical simulations but remains difficult to confir…
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…
DARKSKIES: A suite of super-sampled zoom-in simulations of galaxy clusters with self-interacting dark matter
David Harvey, Yves Revaz, Matthieu Schaller +3
We present the "DARKSKIES" suite of one hundred, zoom-in hydrodynamic simulations of massive ( galaxy clusters with self-interacting dark matt…
Impact of line-of-sight structure on weak lensing observables of galaxy clusters
Felix Vecchi, David Harvey, James Nightingale +3
Weak gravitational lensing observations of galaxy clusters are sensitive to all mass along the line-of-sight, introducing systematic and additional statistical uncertainties due to…
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…
Nulling baryonic feedback in weak lensing surveys using cross-correlations with fast radio bursts
Calvin Leung, Josh Borrow, Kiyoshi W. Masui +4
Baryonic feedback is a leading contaminant in studying dark matter and cosmology using cosmic shear. This has meant omitting much of the data during cosmological inference, or forw…
Signatures of dynamical activity in the hot gas profiles of groups and clusters in the FLAMINGO simulations
Lilia Correa Magnus, Scott T. Kay, Joop Schaye +1
In anticipation of upcoming cosmological surveys, we use the large volume Flamingo hydrodynamical simulations to look for signatures of dynamical activity, focusing on the hot gas…
The resummation model in FLAMINGO: precisely predicting matter power suppression from observed halo baryon fractions
Marcel P. van Daalen, Ioannis Koutalios, Jeger C. Broxterman +4
In order to derive unbiased cosmological parameters from Stage-IV surveys, we need models that can predict the matter power spectrum for at least $k\,\lesssim\,10\,h\mathrm{\,Mpc^{…

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…
