Forged in Quenching: Morphological Transformation across Star-forming and Quiescent Galaxies in EAGLE
Kai Wang, Carlton Baugh, Sownak Bose +15
The connection between morphology and quenching in central galaxies is well established, but its physical origin remains widely debated. We address this by tracing the main progeni…
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…
A statistical look on kinematic planes of satellite galaxies II: The physics behind their early formation in TNG50 MW/M31-like galaxies
Matías Gámez-Marín, Rosa Domínguez-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 semi-analytic model GALFORM to study the full satellite population o…
Large Scale Structure and Environmental Effects on Dwarf Galaxy Growth
Mac M. McMullan, Sownak Bose, Azadeh Fattahi +3
Dwarf galaxies serve as key models for understanding galaxy assembly in the early universe, with their final properties influenced by environmental factors. Using the dark matter-o…
VINTERGATAN-GM: long-lived satellite planes induced by a massive GSE-like merger
R. Rodríguez-Cardoso, S. Roca-Fàbrega, Oscar Agertz +7
Satellite galaxies in the Local Group tend to be distributed in thin, planar configurations, with many sharing coherent orbital motion. Galaxy formation simulations in CDM have…
Andromeda XXXVI: discovery of a new ultra-faint dwarf galaxy towards M31
Joanna D. Sakowska, David Martínez-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 I: frequency and properties in TNG50 MW/M31-like galaxies
Matías Gámez-Marín, Rosa Domínguez-Tenreiro, Isabel Santos-Santos +1
We use the TNG50 simulation to explore the possible existence of satellite galaxy sets, with fixed-in-time identities, forming kinematically-persistent planes (KPPs) along cosmic t…
The unabridged satellite luminosity function of Milky Way-like galaxies in CDM: the contribution of "orphan" satellites
Isabel Santos-Santos, Carlos Frenk, Julio Navarro +2
We study the abundance, radial distribution, and orbits of luminous satellites in simulations of MW-mass dark halos in the LCDM cosmology. We follow the evolution of a halo from th…
The origin of kinematically-persistent planes of satellite galaxies as driven by the early evolution of the local Cosmic Web in CDM
Matías Gámez-Marín, Isabel Santos-Santos, Rosa Domínguez Tenreiro +4
Kinematically-persistent planes of satellites (KPPs) are fixed sets of satellites co-orbiting around their host galaxy, whose orbital poles are conserved and clustered across long…
Anisotropies in the spatial distribution and kinematics of dwarf galaxies in the Local Group and beyond
Isabel M. E. Santos-Santos, Julio F. Navarro, Alan McConnachie
The Local Group (LG) of galaxies is dominated by the M31 and Milky Way (MW) pair, a configuration which suggests that the mass distribution in the LG and its surroundings should be…
Are there any extragalactic high speed dark matter particles in the Solar neighborhood?
Isabel Santos-Santos, Nassim Bozorgnia, Azadeh Fattahi +1
We use the APOSTLE suite of cosmological hydrodynamical simulations of the Local Group to examine the high speed tail of the local dark matter velocity distribution in simulated Mi…
Planes of satellites around simulated disk galaxies II: Time-persistent planes of kinematically-coherent satellites in CDM
Isabel Santos-Santos, Matías Gámez-Marín, Rosa Domínguez-Tenreiro +8
We use two zoom-in CDM hydrodynamical simulations of massive disk galaxies to study the possible existence of fixed satellite groups showing a kinematically-coherent behaviour a…
The Tucana dwarf spheroidal: a distant backsplash galaxy of M31?
Isabel M. E. Santos-Santos, Julio F. Navarro, Alan McConnachie
We use the APOSTLE Local Group (LG) cosmological hydro-simulations to examine the properties of "backsplash" galaxies, i.e, dwarfs which were within the virial boundaries of the Mi…
The cosmic UV background and the beginning and end of star formation in simulated field dwarf galaxies
Matthew Pereira-Wilson, Julio Navarro, Alejandro Benítez-Llambay +1
We use the APOSTLE cosmological simulations to examine the role of the cosmic UV background in regulating star formation (SF) in low-mass LCDM halos. In agreement with earlier work…
The diversity of rotation curves of simulated galaxies with cusps and cores

Satellite mass functions and the faint end of the galaxy mass-halo mass relation in LCDM
Isabel M. E. Santos-Santos, Laura V. Sales, Azadeh Fattahi +1
The abundance of the faintest galaxies provides insight into the nature of dark matter and the process of dwarf galaxy formation. In the LCDM scenario, low mass halos are so numero…
