Ram pressure stripping of a galaxy falling into a \(10^{14}\) M\(_\odot\) cluster. A Mach cone can be seen in front of the galaxy, because it is moving at supersonic speed. Also note how strongly turbulent the tail left behind is.
This simulation is the convergence test of Ruggiero & Lima Neto (2017).
One of the frames of the video above. The tail seems to have features of a Karman vortex street.
Zoom showing how huge a \(10^{15}\) M\(_\odot\) cluster is, compared to a galaxy like the Milky Way. This is the beginning of one of the 36 simulations I ran for Ruggiero & Lima Neto (2017).
All 18 runs of galaxies crossing clusters without a cool-core of Ruggiero & Lima Neto (2017).
All the other 18 runs of Ruggiero & Lima Neto (2017), with the galaxies crossing cool-core clusters this time. The high densities in the cool-cores totally wipe the gaseous disks of the galaxies.
This is a bugged simulation of an isolated galaxy, in which I accidentally got the halo's mass wrong by an order of magnitude. The gas explodes and hits the walls of the periodic box, ending up behaving like a bunch of smoke.
Another bugged simulation. This one had twice the amount of gas it was supposed to have, and got extremely unstable as a consequence.
