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…
Realistic galaxy image simulation via score-based generative models
Michael J. Smith, James E. Geach, Ryan A. Jackson +3
We show that a Denoising Diffusion Probabalistic Model (DDPM), a class of score-based generative model, can be used to produce realistic mock images that mimic observations of gala…
Dark-matter-deficient dwarf galaxies form via tidal stripping of dark matter in interactions with massive companions
R. A. Jackson, S. Kaviraj, G. Martin +11
In the standard Lambda-CDM paradigm, dwarf galaxies are expected to be dark-matter-rich, as baryonic feedback is thought to quickly drive gas out of their shallow potential wells a…
Introducing the NewHorizon simulation: Galaxy properties with resolved internal dynamics across cosmic time
Yohan Dubois, Ricarda Beckmann, Frédéric Bournaud +13
Hydrodynamical cosmological simulations are increasing their level of realism by considering more physical processes and having greater resolution or larger statistics. However, us…
The role of mergers and interactions in driving the evolution of dwarf galaxies over cosmic time
G. Martin, R. A. Jackson, S. Kaviraj +9
Dwarf galaxies (M*<10^9 Msun) are key drivers of mass assembly in high mass galaxies, but relatively little is understood about the assembly of dwarf galaxies themselves. Using the…
The origin of low-surface-brightness galaxies in the dwarf regime
R. A. Jackson, G. Martin, S. Kaviraj +15
Low-surface-brightness galaxies (LSBGs) -- defined as systems that are fainter than the surface-brightness limits of past wide-area surveys -- form the overwhelming majority of gal…
