Evidence for a thermal pressure deficit in galaxy groups from the tSZ effect and weak lensing
Jared Siegel, Alexandra Amon, Jenny E. Greene +3
Measurements of the thermal Sunyaev-Zel'dovich (tSZ) effect have yet to form a consistent picture of the thermodynamic state of the gas in the intracluster medium: their interpreta…
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…
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…
Revealing the neutrino mass through persistent homology of the cosmic web

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…
Implications of a contracted dark matter halo for the Milky Way's inferred virial mass
Diego Dado, Shaun T. Brown, Azadeh Fattahi +2
We investigate how reliably the global properties of Milky Way-mass dark matter haloes can be recovered from dynamical data over a limited radial range, particularly $\lesssim 30~\…
Impact and interplay of CDM analysis choices for LSST cosmic shear
N. C. Robertson, C. Heymans, J. Zuntz +9
We forecast cosmological parameter constraints for a cosmic shear analysis of the Rubin Observatory Legacy Survey of Space and Time (LSST), defining an analysis framework that can…
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…
