Thermal fracturing on comets. Applications to 67P/Churyumov-Gerasimenko
N. Attree, O. Groussin, L. Jorda +12
We simulate the stresses induced by temperature changes in a putative hard layer near the surface of comet 67P/Churyumov--Gerasimenko with a thermo-viscoelastic model. Such a layer…
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…
Forming disc galaxies in major mergers II. The central mass concentration problem and a comparison of GADGET3 with GIZMO
S. A. Rodionov, E. Athanassoula, N. Peschken
Context: In a series of papers, we study the major merger of two disk galaxies in order to establish whether or not such a merger can produce a disc galaxy. Aims: Our aim here is t…
Metallicity-dependendent kinematics and morphology of the Milky Way bulge
E. Athanassoula, S. A. Rodionov, N. Prantzos
We use N-body chemo-dynamic simulations to study the coupling between morphology, kinematics and metallicity of the bar/bulge region of our Galaxy. We make qualitative comparisons…
Forming disk galaxies in wet major mergers. I. Three fiducial examples
E. Athanassoula, S. A. Rodionov, N. Peschken +1
Using three fiducial Nbody+SPH simulations, we follow the merging of two disk galaxies with a hot gaseous halo component each, and examine whether the merger remnant can be a spira…
Bending instability in galactic discs. Advocacy of the linear theory
S. A. Rodionov, N. Ya. Sotnikova
We demonstrate that in N-body simulations of isolated disc galaxies there is numerical vertical heating which slowly increases the vertical velocity dispersion and the disc thickne…
