Learning the Universe: Cosmological and Astrophysical Parameter Inference with Galaxy Luminosity Functions and Colours

Christopher C. Lovell, Tjitske Starkenburg, Matthew Ho +9

We perform the first direct cosmological and astrophysical parameter inference from the combination of galaxy luminosity functions and colours using a simulation based inference ap…

Diverse dark matter profiles in FIRE dwarfs: black holes, cosmic rays and the cusp-core enigma

Sophie Koudmani, Douglas Rennehan, Rachel S. Somerville +5

Dwarf galaxies have historically posed challenges to the cold dark matter (CDM) model and, while many of the so-called 'dwarf galaxy problems' have been mitigated by incorporating…

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…

The impact of feedback on the evolution of gas density profiles from galaxies to clusters: a universal fitting formula from the Simba suite of simulations

Daniele Sorini, Sownak Bose, Romeel Davé +1

The radial distribution of gas within galactic haloes is connected to the star formation rate and the nature of baryon-driven feedback processes. Using six variants of the hydrodyn…

Large-scale dual AGN in large-scale cosmological hydrodynamical simulations

Clara Puerto-Sánchez, Melanie Habouzit, Marta Volonteri +10

Detecting dual active galactic nuclei (DAGN) in observations and understanding theoretically which massive black holes (MBHs) compose them and in which galactic and large-scale env…
