3-D Interaction of a SNR Shock and an Isolated Gas Cloud (Orlando et al. 2005, A&A 444, 505)

3-D visualizations of the mass density evolution during the shock-cloud interaction. The movie shows the density distributions, in log scale.

Crushing of interstellar gas clouds in supernova remnants: X-ray emission
(Orlando et al. 2006, A&A 457, 545)

Evolution of the X-ray emission in the [0.1 - 10] keV band originating from the shock-cloud interaction as derived from models with (model RCm50c10) or without (model HYm50c10) thermal conduction and radiative losses (see Fig. 4 in the paper). The panel on the left shows the corresponding X-ray light curve of the cloud (see Fig. 2 in the paper).

On the origin of asymmetries in bilateral supernova remnants (Orlando et al. 2007, A&A 470, 927)

Synchrotron radio emission (normalized to the maximum of each panel), at t=18 kyrs, synthesized from models assuming a gradient of ambient plasma density (panels A and D) or of ambient magnetic field strength (panels B and E) when the LoS is aligned with the y axis. All the models assume quasi-perpendicular particle injection. The directions of the average unperturbed ambient magnetic field and of the plasma density or magnetic field strength gradient are shown in the upper left and lower right corners of each panel, respectively. The right panels show two examples of radio maps (data adapted from Whiteoak & Green 1996 and Gaensler 1998; the arrows point in the north direction) collected for the SNRs G338.1+0.4 (panel C) and G296.5+10.0 (panel F). The color scale is linear and is given by the bar on the right.
