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…
Towards Reconciling Reionization with JWST: The Role of Bright Galaxies and Strong Feedback
Ankita Bera, Sultan Hassan, Robert Feldmann +2
The elevated UV luminosity functions (UVLF) from recent James Webb Space Telescope (JWST) have challenged the viability of existing theoretical models. To address this, we use a se…
Galaxy assembly bias in cosmological hydrodynamical simulations: a comparison between SIMBA and IllustrisTNG
Hong-Gang Yang, Marcos Pellejero, John Peacock +1
Modelling of large-scale structure is increasingly concerned with galaxy assembly bias (GAB), the dependence of galaxy clustering on quantities other than halo mass. We investigate…
Simba Simulation: The Effect of Feedback Physics on Matter Distribution in the Cosmic Web
Chenze Dong, Florian Dedieu, Daniela Galárraga-Espinosa +3
The discrepancy between the early-time estimation and late-time observation on the cosmic baryon content - the 'missing baryon problem' - is a longstanding problem in cosmology. Al…
