The properties of central stellar knots embedded in galactic bulges of CIELO simulations
Belén Acosta-Tripailao, Patricia B. Tissera, Manuela Zoccali +7
Deeply bound stellar substructures of about 1 kpc at the center of bulges are found in a subset of galaxies from the cosmological chemo-hydrodynamical zoom-in CIELO simulation suit…
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…
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…
Insight into the physical processes that shape the metallicity profiles in galaxies
Brian Tapia-Contreras, Patricia B. Tissera, Emanuel Sillero +6
The distribution of chemical elements in the star-forming regions can store information on the chemical enrichment history of the galaxies. Negative metallicity gradients are expec…
