SMUGGLE-Ring: Evolutionary link between nuclear star cluster and nuclear disk

SungWon Kwak, Mathias Schultheis, Ivan Minchev +8

We present a high-resolution hydrodynamical simulation of the formation and evolution of nuclear structures in a Milky Way-mass galaxy using the SMUGGLE multiphase ISM and stellar…

The SMUGGLE-Ring project: Bar and bulge effects on nuclear disk and ring formation

SungWon Kwak, Federico Marinacci, Matthias Steinmetz +8

We present the first results from the SMUGGLE-Ring project, a suite of simulations employing the SMUGGLE ISM and stellar feedback model to explore nuclear structures in Milky Way-m…

Dark gaps and resonances in barred galaxies

Taehyun Kim, Dimitri A. Gadotti, Myeong-gu Park +4

Dark gaps, low surface brightness regions along the bar minor axis, are expected to form as a consequence of secular evolution in barred galaxies. Although several studies have pro…

Conditions for Bar Formation in Bulgeless Disk Galaxies

Dajeong Jang, Woong-Tae Kim, Yun Hee Lee

While bars are commonly observed in disk galaxies, the precise conditions governing their formation remain incompletely understood. To investigate these conditions, we perform a su…

Dissecting Bar-Induced Stellar Kinematics in Disk Galaxies: The Bisymmetric Model and Rotation Curve Modifications

Seungwon Baek, Woong-Tae Kim, Dajeong Jang +1

We analyze bars formed in -body simulations to investigate two key aspects of stellar kinematic structure of barred galaxies: the angular distributions of the radial and azimuth…

Do strong bars exhibit strong non-circular motions?

Taehyun Kim, Dimitri A. Gadotti, Yun Hee Lee +4

Galactic bars induce characteristic motions deviating from pure circular rotation, known as non-circular motions. As bars are non-axisymmetric structures, stronger bars are expecte…
