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…

Bar Formation in Disc Galaxies: Internal Kinematics and Environmental Influence in MaNGA Galaxies
Erik Aquino-Ortíz, Bernardo Cervantes-Sodi, Karol Chim-Ramirez
We explore how the physical properties of disc galaxies relate to the presence of bars using data from the SDSS-IV MaNGA survey. By combining internal kinematical properties and en…

Study of barred galaxies in IllustrisTNG100: the case of low surface brightness galaxies
Karol Chim-Ramirez, Bernardo Cervantes-Sodi, Yetli Rosas-Guevara +2
In this work, we compare the presence of stellar bars in low and high surface brightness galaxies (LSBs and HSBs, respectively) using the TNG100 simulation of the IllustrisTNG proj…
