Created using the most basic models in the [PLUTO numerical code](http://plutocode.ph.unito.it) for a non-relativistic magnetohydrodynamic jet. The left plot is the toroidal magnetic field strength, and the right plot shows the log density. Terribly simplistic and not overly physically realistic, but looks cool.
These jets are created by black holes, usually the supermassive ones found at the centres of galaxies. Magnetic fields would not normally be considered for these simulations, but we’re going to be looking at the jets very close to the central engine where magnetic effects become significant.
Fantastic stuff, but let me urge you to never again use rainbow/jet colourmap. It’s no longer considered to be good (do a quick Google scholar search to see why). Here maybe use red to blue (although your colourmap should always be tailored to your data).
Good job labeling your charts in GRAD SCHOOL!
Label your axes. This is meaningless without knowing what is being shown and what the scaling is.

is that COMSOL?
Cool! I used to research jets from AGN, so I’m always happy to see more people studying them.
Good luck at your grad school! I’m starting next week doing astro instrumentation, but keep up the good work! 🙂
Cool stuff! Your title had me under the impression that this was your first *using* “Jet” *the colourmap* simulation. Now, *let it be your* ***last***. Jet is a [horrible choice](https://jakevdp.github.io/blog/2014/10/16/how-bad-is-your-colormap/), especially for [colourblind viewers](https://www.mathworks.com/matlabcentral/mlc-downloads/downloads/submissions/30161/versions/4/screenshot.png). Additionally, [Jet makes “features” appear when there aren’t any](https://stats.stackexchange.com/questions/223315/why-use-colormap-viridis-over-jet). To put it simply, “[Jet: it’s famous for how it distorts your data.](https://www.youtube.com/watch?v=xAoljeRJ3lU)”. So now that you’re into your second day of grad school, try using a [perceptually uniform sequential colourmap](https://matplotlib.org/users/colormaps.html) instead.
Nice OP. Very nice!
Star farts?
It seems to be using the _Jet_ colour scheme too.
I love simulations. What are you looking to study in grad school?
Hello ~~darkness~~ comsol my old friend
Ah yeah, CFD. Nice looking graphs that practically anyone can do but almost nobody can do correctly.
Fantastic stuff, but let me urge you to never again use rainbow/jet colourmap. It’s no longer considered to be good (do a quick Google scholar search to see why). Here maybe use red to blue (although your colourmap should always be tailored to your data).
that looks like the cream in the crop
