Stellar bar occurrence in TNG50 and TNG100: disentangling environmental effects and assembly history at z = 0
Karol Chim-Ramirez, Bernardo Cervantes-Sodi, Yetli Rosas-Guevara
In this work, we investigate the dependence of bar presence on environment using TNG50 and TNG100 simulations at z=0. We select disc galaxies within , with stellar mass…
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…
The impact of cosmic voids on AGN activity
Benedict Rouse, Patricia B. Tissera, Yetli Rosas-Guevara +1
From the Eagle project, we study the properties of galaxies hosting AGN in cosmic voids and their surrounding structures, filaments and walls, at , comparing them to non-AGN g…
