Evolution of galaxies in triaxial halos with figure rotation
K. Bekki, K. C. Freeman
Firstly, we demonstrate that unusually large outer HI spiral arms observed in NGC 2915 can form in an extended gas disk embedded in a massive triaxial dark matter halo with slow fi…

Galaxy threshing and the origin of intracluster stellar objects
K. Bekki, W. J. Couch, M. D. Drinkwater +1
We numerically investigate dynamical evolution of non-nucleated dwarf elliptical/spiral galaxies (dE) and nucleated ones (dE,Ns) in clusters of galaxies in order to understand the…

Formation of globular clusters in galaxy mergers
Kenji Bekki, Warrick J. Couch, Duncan A. Forbes +1
Our numerical simulations first demonstrate that the pressure of ISM in a major merger becomes so high ( K ) that GMCs in the merger can coll…
