Recovering the pattern speeds of edge-on barred galaxies via an orbit-superposition method
Yunpeng Jin, Ling Zhu, Behzad Tahmasebzadeh +4
We developed an orbit-superposition method for edge-on barred galaxies and evaluated its capability to recover the bar pattern speed . We selected three simulated galaxies…
The effects of the orbital configurations of mergers on reshaping galaxy structures
Xinyi Wu, Ling Zhu, Jiang Chang +2
We performed a systematic analysis of how the orbital configuration of a merger can influence the structural formation of remnant galaxies using 531 merger pairs selected from Illu…
Distinguishing the formation paths of massive compact ETGs through their internal dynamical structures
Ling Zhu, Ana L. Chies-Santos, Micheli Trindade Moura +1
Massive early-type galaxies (ETGs) are thought to form in two phases: an initial phase of rapid star formation and a later phase of mergers. A small fraction of these galaxies, cal…
Orbital Support and Evolution of CX/OX Structures in Boxy/Peanut Bars
Behzad Tahmasebzadeh, Shashank Dattathri, Monica Valluri +7
Barred galaxies exhibit boxy/peanut or X-shapes (BP/X) protruding from their disks in edge-on views. Two types of BP/X morphologies exist depending on whether the X-wings meet at t…
Equilibrium dynamical models in the inner region of the Large Magellanic Cloud based on Gaia DR3 kinematics
Nikolay Kacharov, Behzad Tahmasebzadeh, Maria-Rosa L. Cioni +3
We use Gaia DR3 to explore how well equilibrium dynamical models based on the Jeans equations and the Schwarzschild orbit superposition method are able to describe LMC's 5-dimensio…
