Cosmic reflections I: the structural diversity of simulated and observed low-mass galaxy analogues

G. Martin, A. E. Watkins, Y. Dubois +10

Dwarf galaxies serve as powerful laboratories for investigating the underlying physics of galaxy evolution including the impact of baryonic feedback processes and environmental inf…

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…

Signatures of simulated spiral arms on radial actions

P. A. Palicio, A. Recio-Blanco, T. Tepper-Garcia +7

Among the various implications of the spiral arms, it has been observed in the Milky Way disc that the distribution of radial actions from the Gaia Data Release 3 exhibits structur…

New tools for studying planarity in galaxy satellite systems: Milky Way satellite planes are consistent with ΛCDM

E. Uzeirbegovic, G. Martin, S. Kaviraj +8

We introduce a new concept -- termed "planarity" -- which aims to quantify planar structure in galaxy satellite systems without recourse to the number or thickness of planes. We us…

Black hole spin evolution across cosmic time from the NewHorizon simulation

Ricarda S. Beckmann, Yohan Dubois, Marta Volonteri +8

Astrophysical black holes (BHs) have two fundamental properties: mass and spin. While the mass-evolution of BHs has been extensively studied, much less work has been done on predic…
