Optimal softening for force calculations in collisionless N-body simulations
E. Athanassoula, E. Fady, J. -C. Lambert +1
In N-body simulations the force calculated between particles representing a given mass distribution is usually softened, to diminish the effect of graininess. In this paper we stud…

Bar Diagnostics in Edge-On Spiral Galaxies. II. Hydrodynamical Simulations
E. Athanassoula, M. Bureau
We develop diagnostics based on gas kinematics to identify the presence of a bar in an edge-on spiral galaxy and determine its orientation. We use position-velocity diagrams (PVDs)…

Bar Diagnostics in Edge-On Spiral Galaxies. I. The Periodic Orbits Approach
M. Bureau, E. Athanassoula
We develop diagnostics to detect the presence and orientation of a bar in an edge-on disk, using its kinematical signature in the position-velocity diagram (PVD) of a spiral galaxy…
