The NIVARIA-Local Group simulations: Unveiling the origin of rotation curve diversity in dwarf galaxies and its connection to galaxy morphology
A. Contreras-Santos, A. Di Cintio, A. Negri +7
Dwarf galaxies exhibit a large diversity in rotation curve shapes, challenging galaxy formation models within the CDM paradigm. We present NIVARIA-LG, a new suite of cosmologica…
Reconstructing the orbits of Milky Way dwarf galaxies: A Large Magellanic Cloud perspective
Alberto Manuel Martínez-García, Andrés del Pino, Roeland P. van der Marel +14
The orbital histories of the dwarf satellites of the Milky Way (MW) are key to understanding their evolution and placing their present-day properties in a dynamical context. We pre…
Bulgeless Evolution And the Rise of Discs (BEARD) I. Physical drivers of the mass-size relation for Milky Way-like galaxies
C. Marrero-de la Rosa, J. Méndez-Abreu, A. de Lorenzo-Cáceres +20
In the standard cold dark matter (CDM) cosmology, the existence of massive pure-disc galaxies remains challenging within the hierarchical framework and is key to understandi…
Bulgeless Evolution And the Rise of Discs (BEARD) III. A numerical simulation view of satellites around Milky-Way analogues
Salvador Cardona-Barrero, Jairo Méndez-Abreu, Adriana de Lorenzo-Cáceres +17
. The existence of massive disc galaxies with little or no bulge challenges conventional cold dark matter model, which typically favours dynamically hot central structure…
Bulgeless Evolution And the Rise of Discs (BEARD) II. The role of mergers in shaping the Milky Way analogues in TNG50
Yetli Rosas-Guevara, Jairo Méndez-Abreu, Adriana de Lorenzo-Cáceres +20
We study the formation and evolution of bulgeless galaxies within the Milky Way-Andromeda analogue sample of the TNG50 simulation. Through kinematic decomposition with Mordor, we i…
HI-bearing dark galaxies predictions from constrained Local Group simulations: how many and where to find them
Guacimara García-Bethencourt, Arianna Di Cintio, Sébastien Comerón +7
Dark galaxies are small, DM-dominated halos whose gas remains in hydrostatic and thermal equilibrium and has never formed stars. They are of particular interest because they repres…
Portrait of a Galaxy on FIRE: Is the -bimodality a natural consequence of inside-out disc growth in a hierarchical formation scenario?
María Benito, Annaliina Aavik, Giuseppina Battaglia +7
The chemical dichotomy in the [/Fe]-[Fe/H] plane is a consequence of the complex processes underlying the formation and evolution of disc galaxies such as observed in the stella…
A physically motivated galaxy size definition across different state-of-the-art hydrodynamical simulations
Elena Arjona-Galvez, Salvador Cardona-Barrero, Robert J. J. Grand +6
Galaxy sizes are a key parameter to distinguishing between different galaxy types and morphologies, reflecting their formation and assembly histories. Several methods define galaxy…
On the anti-correlation between pericentric distance and inner dark matter density of Milky Way's dwarf spheroidal galaxies
Salvador Cardona-Barrero, Giuseppina Battaglia, Carlo Nipoti +1
An anti-correlation between the central density of the dark matter halo () and the pericentric distances () of the Milky Way's (MW's) dwarf spheroidal ga…
The undiscovered ultra-diffuse galaxies of the Local Group
Oliver Newton, Arianna Di Cintio, Salvador Cardona-Barrero +6
Ultra-diffuse galaxies (UDGs) are attractive candidates to probe cosmological models and test theories of galaxy formation at low masses; however, they are difficult to detect beca…
Metallicity profiles of Ultra Diffuse Galaxies in NIHAO simulations
S. Cardona-Barrero, A. Di Cintio, G. Battaglia +2
Supernovae feedback driven expansion has proven to be a viable mechanism to explain the average properties of Ultra Diffuse Galaxies (UDGs) such as the sizes, colors, mass and inte…
Origin of stellar prolate rotation in a cosmologically simulated faint dwarf galaxy
Salvador Cardona-Barrero, Giuseppina Battaglia, Arianna Di Cintio +2
Stellar prolate rotation in dwarf galaxies is rather uncommon, with only two known galaxies in the Local Group showing such feature (Phoenix and And II). Cosmological simulations s…
NIHAO XXIV: Rotation or pressure supported systems? Simulated Ultra Diffuse Galaxies show a broad distribution in their stellar kinematics
Salvador Cardona-Barrero, Arianna Di Cintio, Christopher B. A. Brook +4
In recent years a new window on galaxy evolution opened, thanks to the increasing discovery of galaxies with a low surface brightness, such as Ultra Diffuse Galaxies (UDGs). The fo…
NIHAO XXI: The emergence of Low Surface Brightness galaxies
Arianna Di Cintio, Chris B. Brook, Andrea V. Macciò +2
The existence of galaxies with a surface brightness lower than the night sky has been known since three decades. Yet, their formation mechanism and emergence within a …
