Interpretable machine learning of halo gas density profiles: a sensitivity analysis of cosmological hydrodynamical simulations

Daniele Sorini, Sownak Bose, Mathilda Denison +1

Stellar and AGN-driven feedback processes affect the distribution of gas on a wide range of scales, from within galaxies well into the intergalactic medium. Yet, it remains unclear…

The AURORA Survey: High-Redshift Empirical Metallicity Calibrations from Electron Temperature Measurements at z=2-10

Ryan L. Sanders, Alice E. Shapley, Michael W. Topping +29

We present detections of auroral emission lines of [OIII], [OII], [SIII], and [SII] in deep JWST/NIRSpec spectroscopy for 41 star-forming galaxies at from the AURORA su…

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…

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…

Introducing RAFIKI: Refining AGN Feedback in Kinetic Implementations

Skylar Grayson, Evan Scannapieco, Romeel Davé +2

Modern cosmological simulations have now matured to the point of reproducing the evolution of realistic galaxy populations across cosmic time. These simulations rely on feedback fr…

Star-forming galaxies in the cosmic web in the last 11 Gyr

B. Jego, K. Kraljic, M. Béthermin +1

We investigate how the star formation activity of galaxies depends on their position within the cosmic web using the SIMBA cosmological simulation from redshift to . Whi…
