Two-component self-gravitating isothermal slab models
Giuseppe Bertin, Francesco Pegoraro
We revisit the problem of the isothermal slab (in standard Cartesian coordinates, density distributions and mean gravitational potential are considered to be independent of and…
A simple two-component description of energy equipartition and mass segregation for anisotropic globular clusters
Stefano Torniamenti, Giuseppe Bertin, Paolo Bianchini
In weakly collisional stellar systems such as some globular clusters, partial energy equipartition and mass segregation are expected to develop as a result of the cumulative effect…
Disk heating and bending instability in galaxies with counterrotation
Sergey Khoperskov, Giuseppe Bertin
With the help of high-resolution long-slit and integral-field spectroscopy observations, the number of confirmed cases of galaxies with counterrotation is increasing rapidly. The e…
A class of spherical, truncated, anisotropic models for application to globular clusters
Ruggero de Vita, Giuseppe Bertin, Alice Zocchi
Recently, a class of non-truncated radially-anisotropic models (the so-called -models), originally constructed in the context of violent relaxation and modeling of ellipti…
Synthetic HI observations of spiral structure in the outer disk in galaxies
S. A. Khoperskov, G. Bertin
By means of 3D hydrodynamical simulations, in a separate paper we have discussed the properties of non-axisymmetric density wave trains in the outermost regions of galaxy disks, ba…
Rotating Globular Clusters
P. Bianchini, A. L Varri, G. Bertin +1
Internal rotation is considered to play a major role in the dynamics of some globular clusters. However, in only few cases it has been studied by quantitative application of realis…
