Reconstructing the orbits of Milky Way dwarf galaxies: A Large Magellanic Cloud perspective
Alberto Manuel Martínez-García, 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…
High-redshift Merger-induced Bar-like Galaxies in IllustrisTNG
Ewa L. Lokas
Recent discoveries made with JWST observations include a significant number of barred galaxies at high redshift. Their origin remains unclear and their presence seems difficult to…
A new tidal scenario for double bar formation
Marcin Semczuk, Ewa L. Łokas, Adriana de Lorenzo-Cáceres +1
Double bars make up a significant fraction of barred galaxies. We propose a new formation scenario for double bars that involves tidal interactions. We demonstrate the viability of…
Revealing the Structure and Internal Rotation of the Sagittarius Dwarf Spheroidal Galaxy with Gaia and Machine Learning
Andrés del Pino, Mark A. Fardal, Roeland P. van der Marel +3
We present a detailed study of the internal structure and kinematics of the core of the Sagittarius dwarf spheroidal galaxy (Sgr). Using machine-learning techniques, we have combin…
Dark matter distribution and dynamics of dwarf spheroidal galaxies
Ewa L. Lokas
I review the current status of dynamical modelling of dwarf spheroidal galaxies focusing on estimates of their dark matter content. Starting with the simplest methods using the vel…
