CAMELS Environments: The Impact of Local Neighbours on Galaxy Evolution across the SIMBA, IllustrisTNG, ASTRID, and Swift-EAGLE Simulations

Xavier Sims, Daniel Anglés-Alcázar, Boon-Kiat Oh +6

Internal feedback from massive stars and active galactic nuclei (AGN) play a key role in galaxy evolution, but external environmental effects can also strongly influence galaxies.…

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…

Introducing the Descriptive Parametric Model: Gaseous Profiles for Galaxies, Groups, and Clusters

Benjamin D. Oppenheimer, G. Mark Voit, Yannick M. Bahé +14

We develop and present the Descriptive Parametric Model (DPM), a tool for generating profiles of gaseous halos (pressure, electron density, and metallicity) as functions of radius,…

Constraining Baryonic Feedback Effects on the Matter Power Spectrum with Fast Radio Bursts

Isabel Medlock, Daisuke Nagai, Daniel Anglés Alcázar +1

In the age of large-scale galaxy and lensing surveys, such as DESI, Euclid, Roman and Rubin, we stand poised to usher in a transformative new phase of data-driven cosmology. To ful…

X-raying CAMELS: Constraining Baryonic Feedback in the Circum-Galactic Medium with the CAMELS simulations and eRASS X-ray Observations

Erwin T. Lau, Daisuke Nagai, Ákos Bogdán +7

The circumgalactic medium (CGM) around massive galaxies plays a crucial role in regulating star formation and feedback. Using the CAMELS simulation suite, we develop emulators for…
