FLAMINGO: Galaxy formation and feedback effects on the gas density and velocity fields
Lurdes Ondaro-Mallea, Raul E. Angulo, Giovanni Aricò +3
Most of the visible matter in the Universe is in a gaseous state, subject to hydrodynamic forces and galaxy formation processes that are much more complex to model than gravity. Th…
A 1% accurate method to include baryonic effects in galaxy-galaxy lensing models
Matteo Zennaro, Giovanni Aricò, Carlos García-García +6
Galaxy clustering and galaxy-galaxy lensing are two of the main observational probes in Stage-IV large-scale structure surveys. Unfortunately, the complicated relationship between…
The FLAMINGO project: cosmology with the redshift dependence of weak gravitational lensing peaks
Jeger C. Broxterman, Matthieu Schaller, Henk Hoekstra +5
Weak gravitational lensing (WL) convergence peaks contain valuable cosmological information in the regime of non-linear collapse. Using the FLAMINGO suite of cosmological hydrodyna…
Weak lensing constraints on the stellar-to-halo mass relation of galaxy groups with simulation-informed scatter
Shun-Sheng Li, Henk Hoekstra, Konrad Kuijken +2
Understanding the scaling relation between baryonic observables and dark matter halo properties is crucial not only for studying galaxy formation and evolution, but also for derivi…
FLAMINGO: combining kinetic SZ effect and galaxy-galaxy lensing measurements to gauge the impact of feedback on large-scale structure
Ian G. McCarthy, Alexandra Amon, Joop Schaye +13
Energetic feedback processes associated with accreting supermassive black holes can expel gas from massive haloes and significantly alter various measures of clustering on ~Mpc sca…
The FLAMINGO project: Baryon effects on the matter power spectrum
Matthieu Schaller, Joop Schaye, Roi Kugel +2
The effect of baryon physics associated with galaxy formation onto the large-scale matter distribution of the Universe is a key uncertainty in the theoretical modelling required fo…
The abundance and nature of high-redshift quiescent galaxies from JADES spectroscopy and the FLAMINGO simulations
William M. Baker, Seunghwan Lim, Francesco D'Eugenio +20
We use NIRSpec/MSA spectroscopy and NIRCam imaging to study a sample of 18 massive (dex), central quiescent galaxies at in the GOO…
The effects of super-Eddington accretion and feedback on the growth of early supermassive black holes and galaxies
Filip Huško, Cedric G. Lacey, William J. Roper +3
We present results of cosmological zoom-in simulations of a massive protocluster down to redshift (when the halo mass is M) using the SWIFT cod…
Hydrostatic mass bias for galaxy groups and clusters in the FLAMINGO simulations
Joey Braspenning, Joop Schaye, Matthieu Schaller +2
The masses of galaxy clusters are commonly measured from X-ray observations under the assumption of hydrostatic equilibrium (HSE). This technique is known to underestimate the true…
The FLAMINGO Project: An assessment of the systematic errors in the predictions of models for galaxy cluster counts used to infer cosmological parameters
Roi Kugel, Joop Schaye, Matthieu Schaller +2
Galaxy cluster counts have historically been important for the measurement of cosmological parameters and upcoming surveys will greatly reduce the statistical errors. To exploit th…
Validating the clustering predictions of empirical models with the FLAMINGO simulations
Sergio Contreras, Raul E. Angulo, Jonás Chaves-Montero +3
Context. Mock galaxy catalogues are essential for correctly interpreting current and future generations of galaxy surveys. Despite their significance in galaxy formation and cosmol…
The FLAMINGO Project: A comparison of galaxy cluster samples selected on mass, X-ray luminosity, Compton-Y parameter, or galaxy richness
Roi Kugel, Joop Schaye, Matthieu Schaller +5
Galaxy clusters provide an avenue to expand our knowledge of cosmology and galaxy evolution. Because it is difficult to accurately measure the total mass of a large number of indiv…
Dark photon constraints from CMB temperature anisotropies
Andres Aramburo-Garcia, Kyrylo Bondarenko, Alexey Boyarsky +6
The resonant conversion, within the inter-galactic medium, of regular photons into dark photons amplifies the anisotropy observed in the CMB, thereby imposing stringent constraints…
Relativistic SZ temperatures and hydrostatic mass bias for massive clusters in the FLAMINGO simulations
Scott T. Kay, Joey Braspenning, Jens Chluba +4
The relativistic Sunyaev-Zel'dovich (SZ) effect can be used to measure intracluster gas temperatures independently of X-ray spectroscopy. Here, we use the large-volume FLAMINGO sim…
TangoSIDM Project: Is the Stellar Mass Tully-Fisher relation consistent with SIDM?
Camila Correa, Matthieu Schaller, Joop Schaye +3
Self-interacting dark matter (SIDM) has the potential to significantly influence galaxy formation in comparison to the cold, collisionless dark matter paradigm (CDM), resulting in…
The FLAMINGO project: the coupling between baryonic feedback and cosmology in light of the tension
Willem Elbers, Carlos S. Frenk, Adrian Jenkins +12
