Statistics of the projected angles between the black-hole spin and the host-galaxy rotation axes from NewHorizon

Sebastien Peirani, Yasushi Suto, Clotilde Laigle +3

Understanding the alignment between AGN jets and their host galaxies is crucial for interpreting AGN unification models, jet feedback processes, and the co-evolution of galaxies an…

On the Origin of Gas-stripping of Galaxies in Group Environments

Jinsu Rhee, Christophe Pichon, Yohan Dubois +12

We investigate how low-mass group environments () influence the gas content of their satellite galaxies with using…

The dwarf stellar mass function in different environments and the lack of a generic missing dwarfs problem in ΛCDM

Ilin Lazar, Sugata Kaviraj, Garreth Martin +9

We combine deep photometric data in the COSMOS and XMM-LSS fields with high-resolution cosmological hydrodynamical simulations to explore two key questions: (1) how does the galaxy…

How Dust Models Shape High-z Galaxy Morphology: Insights from the NewCluster Simulation

Gyeong-Hwan Byun, J. K. Jang, Zachary P. Scofield +10

Dust plays a pivotal role in shaping the observed morphology of galaxies. While traditional cosmological simulations often assume a fixed dust-to-gas (DTG) or dust-to-metal (DTM) m…

Dissecting the formation of gas-versus-star counter-rotating galaxies from the NewHorizon simulation

S. Peirani, Y. Suto, S. Han +5

(Reduced)Using the NewHorizon simulation, we have studied ten gas-versus-star counter-rotating galaxies in field environments with a stellar mass of M*~[1-5]x10^10 Msun. For all of…

2D light distributions of dwarf galaxies -- key tests of the implementation of physical processes in simulations

Aaron Watkins, Garreth Martin, Sugata Kaviraj +5

Cosmological simulations provide much of the theoretical framework within which we interpret extragalactic observations. However, even if a given simulation reproduces the integrat…
