Cosmological constraining power of the redshifts, heights, and angular clustering of weak gravitational lensing peaks

Jeger C. Broxterman, Matthieu Schaller, Ian G. McCarthy +8

Weak gravitational lensing (WL) peaks probe non-Gaussian information of the large-scale distribution of matter that is not captured by two-point lensing statistics. We study the co…

The FLAMINGO simulations data release

John C. Helly, Robert J. McGibbon, Joop Schaye +15

We describe the public release of petabytes of data from the FLAMINGO cosmological simulations. The suite consists of hydrodynamical simulations that include radiative cooli…

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…

FLAMINGO: The thermal history of the Universe from tSZ effect cross-correlations and its dependencies on cosmology and baryon physics

Jaime Salcido, Tianyi Yang, Ian G. McCarthy +9

The cross-correlation between tracers of large-scale structure, such as galaxies or quasars, and the thermal Sunyaev-Zel'dovich (tSZ) signal yields a measure of the bias-weighted m…

Constraining baryonic feedback and cosmology from DES Y3 and Planck PR4 62pt data. I. CDM models

Jiachuan Xu, Tim Eifler, Elisabeth Krause +3

We combine weak lensing, galaxy clustering, cosmic microwave background (CMB) lensing, and their cross-correlations (so-called 62pt) to constrain cosmology and baryonic fee…

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…
