The descendants of JWST galaxies in the COLIBRE simulations
Xu Zhao, Carlos S. Frenk, Andrew Pontzen +9
Recent observations with JWST have revealed a population of UV-bright galaxies at . This discovery naturally raises the question: what do such early galaxies evolve in…
Ruffled Feathers: Merger-driven galaxy size growth and structural transformation in EAGLE
Kai Wang, Carlton Baugh, Sownak Bose +9
Galaxy mergers drive both the size growth and the transformation from discs to spheroids, yet the prescriptions used to model these processes in semi-analytic frameworks have not b…
Inflow-driven galaxy evolution - I. Revealing the physics of the fundamental metallicity relation
Kai Wang, Carlton Baugh, N. F. Boardman +11
We present a unified physical framework for the fundamental metallicity relation (FMR), based on the mass-continuity equations. The FMR is not merely the anti-correlation between s…
Andromeda XXXVI: discovery of a new ultra-faint dwarf galaxy towards M31
Joanna D. Sakowska, David MartÃnez-Delgado, Michelle L. M. Collins +4
We present deep imaging of Andromeda XXXVI (And XXXVI), a dwarf galaxy discovered through visual inspection of the Pan-Andromeda Archaeological Survey, using observations obtained…
A statistical look on kinematic planes of satellite galaxies II: The physics behind their early formation in TNG50 MW/M31-like galaxies
MatÃas Gámez-MarÃn, Rosa DomÃnguez-Tenreiro, Isabel Santos-Santos +2
We investigate the physical origin of kinematically persistent planes (KPPs) of satellite galaxies in a sample of 190 Milky Way (MW)/M31-like host-satellite systems drawn from the…
The missing ultra-faint satellites of the Milky Way
Isabel M. E. Santos-Santos, Carlos S. Frenk, Julio F. Navarro
We combine the highest resolution N-body simulation of a CDM halo (Aquarius-A) with the {\sc GALFORM} galaxy formation semianalytic model to study the…
