Five methods for determining pattern speeds in galaxies
Daniel Pfenniger, Kanak Saha, Yu-Ting Wu
Aims. New or refined methods for determining instantaneous scalar and vector pattern speeds from a restricted domain are developed, for applications in N-body simulations or in gal…
The Effect of Impact Parameters on the Formation of Massive Black Hole Binaries in Galactic Mergers
Yu-Heng Ho, Ing-Guey Jiang, Yu-Ting Wu
By employing N-body simulations, we inestigate the formation of massive black hole binaries (MBHBs) through the sinking of two massive black holes (MBHs) during galaxy mergers. Wit…
Morphological and Kinematical Analysis of the Double-barred Galaxy NGC 3504 Using ALMA CO (2-1) Data
Yu-Ting Wu, Alfonso Trejo, Daniel Espada +1
We present results obtained from ALMA CO (2-1) data of the double-barred galaxy NGC 3504. With three times higher angular resolution (~ 0."8) than previous studies, our observation…
Time-dependent Pattern Speeds in Barred Galaxies
Yu-Ting Wu, Daniel Pfenniger, Ronald E. Taam
Based on a high quality -body simulation of a double bar galaxy model, we investigate the evolution of the bar properties, including their size, strength and instantaneous patte…
Time-dependent Corotation Resonance in Barred Galaxies
Yu-Ting Wu, Daniel Pfenniger, Ronald E. Taam
The effective potential neighboring the corotation resonance region in barred galaxies is shown to be strongly time-dependent in any rotating frame because of the competition of ne…
On the Formation of Elliptical Rings in Disk Galaxies
Yu-Ting Wu, Ing-Guey Jiang
N-body simulations of galactic collisions are employed to investigate the formation of elliptical rings in disk galaxies. The relative inclination between disk and dwarf galaxies i…
