Manifold spirals, disc-halo interactions and the secular evolution in N-body models of barred galaxies
C. Efthymiopoulos, P. E. Kyziropoulos, R. I. Paez +2
The manifold theory of barred-spiral structure provides a dynamical mechanism explaining how spiral arms beyond the ends of galactic bars can be supported by chaotic flows extendin…

Structures induced by companions in galactic discs
P. Kyziropoulos, C. Efthymiopoulos, G. Gravvanis +1
Using N-body simulations we study the structures induced on a galactic disc by repeated flybys of a companion in decaying eccentric orbit around the disc. Our system is composed by…
