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…
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…
Black hole mergers from dwarf to massive galaxies with the NewHorizon and Horizon-AGN simulations
Marta Volonteri, Hugo Pfister, Ricarda S. Beckman +12
Massive black hole (MBH) coalescences are powerful sources of low-frequency gravitational waves. To study these events in the cosmological context we need to trace the large-scale…
Why do extremely massive disc galaxies exist today?
Ryan A. Jackson, Garreth Martin, Sugata Kaviraj +4
Galaxy merger histories correlate strongly with stellar mass, largely regardless of morphology. Thus, at fixed stellar mass, spheroids and discs share similar assembly histories, b…
Massive spheroids can form in single minor mergers
R. A. Jackson, G. Martin, S. Kaviraj +4
Understanding how rotationally-supported discs transform into dispersion-dominated spheroids is central to our comprehension of galaxy evolution. Morphological transformation is la…
