Bar Formation and Destruction in the FIRE-2 Simulations

The Astrophysical Journal
The physical mechanisms responsible for bar formation and destruction in galaxies remain a subject of debate. While we have gained valuable insight into how bars form and evolve from isolated idealized simulations, in the cosmological domain, galactic ...

The Stellar Bar–Dark Matter Halo Connection in the TNG50 Simulations

The Astrophysical Journal
Stellar bars in disk galaxies grow as stars in near-circular orbits lose angular momentum to their environments, including their dark matter (DM) halo, and transform into elongated bar orbits.

Diverse lifestyles of bar-like galaxies and their coevolution with the brightest galaxy in the most massive cluster of TNG50

Astronomy & Astrophysics
Clusters can provide propitious environments for bar formation in galaxies. This work studies the formation and evolution of 15 bar-like galaxies in the most massive cluster of the TNG50 simulation from the IllustrisTNG suite.

Cyclic response of RC beam-column joints reinforced with plain bars: an experimental testing campaign [PDF]

, 2012
Existing reinforced concrete (RC) buildings constructed until the mid-70’s, with plain reinforcing bars, are expected to behave poorly when subjected to earthquake actions.

The Hot and Energetic Universe:The evolution of galaxy groups and clusters [PDF]

, 2013
Major astrophysical questions related to the formation and evolution of structures, and more specifically of galaxy groups and clusters, will still be open in the coming decade and beyond: what is the interplay of galaxy, supermassive black hole, and ...

Connection between Nonaxisymmetric Structures and Neutral Gas Distribution in Disk Galaxies

The Astrophysical Journal
Nonaxisymmetric structures, such as bars and spiral arms, are known to concentrate molecular gas and star formation in galaxy centers, actively building up the pseudobulges.
