GalPort: Investigation of the bar in action-angle space
Viktor D. Zozulia
GalPort is a Python package for analysing the orbital dynamics of evolving disc galaxy numerical models in action-angle space. The package implements novel numerical methods for ef…
Boxy/Peanut Bulges: Comparative Analysis of EGIPS Galaxies and TNG50 Models
Anton Smirnov, Alexander Marchuk, Viktor Zozulia +2
We investigated the properties of boxy/peanut-shaped (B/PS) bulges in a sample of 71 galaxies from the Edge-on Galaxies in the Pan-STARRS Survey (EGIPS) and 20 simulated galaxies f…
Phase-space distortion as a key to unraveling galactic bar buckling
Viktor D. Zozulia, Natalia Ya. Sotnikova, Anton A. Smirnov
For the first time, we investigate the resonant structure of -body galactic bar at the stage of buckling using action-angle variables. We studied the evolution of vertical actio…
Boxy/peanut shaping of a mature galactic bar in action-angle space
Viktor D. Zozulia, Anton A. Smirnov, Natalia Ya. Sotnikova +1
We study vertical resonant trapping and resonant heating of orbits. These two processes both lead to the growth of a boxy/peanut-shaped bulge in a typical -body model. For the f…
Positive Lynden-Bell derivative as a ticket to the bar trap?
Viktor D. Zozulia, Anton A. Smirnov, Natalia Ya. Sotnikova
We have translated the results of -body simulations of one barred model into the language of action variables and frequencies. Using this language, we analysed the behaviour of…
B/PS bulges in DESI Legacy edge-on galaxies I: Sample building
Alexander A. Marchuk, Anton A. Smirnov, Natalia Y. Sotnikova +6
We present the biggest up-to-date sample of edge-on galaxies with B/PS bulges and X-structures. The sample was prepared using images from the DESI Legacy catalogue and contains abo…
