EVN Observations of GRS1915+105
L. Feretti, G. Giovannini, M. Tordi +12
We obtained EVN observations of the X-ray transient source GRS1915+105 in its radio-loud state. In 2 images obtained before a major flare, the source is resolved, showing two oppos…
On the matter entrainment by stellar jets and the acceleration of molecular outflows
M. Micono, G. Bodo, S. Massaglia +2
We study, by numerical simulations, the entrainment process in a supersonic, radiative jet flow, during the evolution of Kelvin-Helmholtz instabilities, in the context of the the a…
Kelvin-Helmholtz instability in three dimensional radiative jets
M. Micono, G. Bodo, S. Massaglia +3
The analysis of the stability properties of astrophysical jets against Kelvin-Helmholtz (or shear-layer) instabilities plays a basic role in the understanding the origin and physic…
Understanding NLR in Seyfert Galaxies: numerical simulation of jet-cloud interaction
P. Rossi, A. Capetti, G. Bodo +2
Recent HST observations suggest that the NLR in Seyfert Galaxies can be the result of interaction between jet and external inhomogeneous medium; following this suggestion we perfor…
Acoustic Waves in a Stratified Atmosphere: II. Three-Dimensional Hydrodynamics
G. Bodo, W. Kalkofen, S. Massaglia +1
We investigate analytically the propagation of linear waves in a three-dimensional, nonmagnetic, isothermal atmosphere stratified in plane-parallel layers. The motivation is to stu…
Diffusive shock acceleration in extragalactic jets
M. Micono, N. Zurlo, S. Massaglia +2
We calculate the temporal evolution of distributions of relativistic electrons subject to synchrotron and adiabatic processes and Fermi-like acceleration in shocks. The shocks resu…
