Reconstructing the orbits of Milky Way dwarf galaxies: An LMC perspective
Alberto Manuel MartÃnez-GarcÃa, 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…
Cluster-centric trends in bar size and pattern speed: the case of Abell 2199
Chandan Watts, Sudhanshu Barway, Mousumi Das +1
We investigate how the environment of a dynamically unrelaxed galaxy cluster influences the structure and dynamics of stellar bars. In particular, we examine cluster-centric variat…
Diverse lifestyles of bar-like galaxies and their coevolution with the brightest galaxy in the most massive cluster of TNG50
Ewa L. Lokas
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…
Tidally induced bar-like galaxies in simulated clusters
Ewa L. Lokas
One of the scenarios for bar formation in galaxies involves their interaction with a more massive companion. The stellar component is then transformed from a disk into a bar-like p…
The oldest tidally induced bar-like galaxy in the IllustrisTNG cluster
Ewa L. Lokas
New JWST observations have revealed the presence of a significant number of high-redshift barred galaxies. The origin of these bars remains unclear, and their properties appear dif…
On the nature of buckling instability in galactic bars
Ewa L. Lokas
Many strong simulated galactic bars experience buckling instability, which manifests itself as a vertical distortion out of the disk plane, and later dissipates. Using a simulation…
