Roman Early-Definition Astrophysics Survey Opportunity: Galactic Roman Infrared Plane Survey (GRIPS)
Roberta Paladini, Catherine Zucker, Robert Benjamin +67
A wide-field near-infrared survey of the Galactic disk and bulge/bar(s) is supported by a large representation of the community of Galactic astronomers. The combination of sensitiv…
Basis function expansions for galactic dynamics: Spherical versus cylindrical coordinates
Yougang Wang, E. Athanassoula, Shude Mao
Aims. The orbital structure of galaxies is strongly influenced by the accuracy of the force calculation during orbit integration. We explore the accuracy of force calculations for…
Forming disc galaxies in major mergers: III. The effect of angular momentum on the radial density profiles of disc galaxies
N. Peschken, E. Athanassoula, S. A. Rodionov
We study the effect of angular momentum on the surface density profiles of disc galaxies, using high resolution simulations of major mergers whose remnants have downbending radial…
Orbital classification in an N-body bar
Yougang Wang, E. Athanassoula, Shude Mao
The dynamics and evolution of any galactic structure are strongly influenced by the properties of the orbits that constitute it. In this paper, we compare two orbit classification…
Applying Schwarzschild's orbit superposition method to barred or non-barred disc galaxies
Eugene Vasiliev, E. Athanassoula
We present an implementation of the Schwarzschild orbit superposition method which can be used for constructing self-consistent equilibrium models of barred or non-barred disc gala…
Adventures of a tidally induced bar
E. L. Lokas, E. Athanassoula, V. P. Debattista +5
Using N-body simulations, we study the properties of a bar induced in a dwarf galaxy as a result of tidal interaction with the Milky Way. The dwarf is initially composed of a disk…
