Bar-Halo Friction in Galaxies II: Metastability
J. A. Sellwood, Victor P. Debattista
It is well-established that strong bars rotating in dense halos generally slow down as they lose angular momentum to the halo through dynamical friction. Angular momentum exchanges…
Double barred galaxies at intermediate redshifts: A feasibility study
Thorsten Lisker, Victor P. Debattista, Ignacio Ferreras +1
Despite the increasing number of studies of barred galaxies at intermediate and high redshifts, double-barred (S2B) systems have only been identified in the nearby (z<0.04) univers…
The Secular Evolution of Disk Structural Parameters
Victor P. Debattista, Lucio Mayer, C. Marcella Carollo +3
We present a comprehensive series of -body as well as -body + SPH simulations to study the secular evolution of the structure of disk galaxies. Our simulations are organized…
The Kinematic Signature of Face-On Peanut-Shaped Bulges
Victor P. Debattista, C. Marcella Carollo, Lucio Mayer +1
We present a kinematic diagnostic for peanut-shaped bulges in nearly face-on galaxies. The face-on view provides a novel perspective on peanuts which would allow study of their rel…
