New study in preprint. In this study we test if supernova-driven turbulence, a large component of the turbulence in our Galaxy, resembles classical Kolmogorov-style turbulence, as it is regularly assumed. It does not.

@PMocz Thanks! Stable streamline integration is a must if you want to advect long distances, but post-processing is what sells it. @astro_magnetism recommended high pass filtering and multiple passes of the LIC, which makes the final result so much better!

[Neco Kriel @AstroKriel]

Did you wish for a fast and simple LIC code this Christmas? Well, look no further! I wrote one you can have for free, and a week early! Happy holidays! 🎄🎅

@juandiegosoler I've made a stand-alone repo, that way there are less dependencies involved. Have a look and let me know what you think!

I wrote some code to compute LICs (a way to visualise vector fields), and you know what, I think its working pretty well if you ask me!

[Neco Kriel @AstroKriel]

@juandiegosoler Great, will do! Gimme a few days :-)

[Neco Kriel @AstroKriel]

@juandiegosoler Yep, applies a LIC over a domain size of 1000^2 cells, with a kernel length of 150 cells, in under half a second! What's nice, though, is the streamline advection is accurate, so large kernels are stable, and you can apply multiple passes to create higher contrast results

I present you with a close-up from one of my simulations, diving into the chaotic world of turbulent plasma in the intracluster medium!

I wish they'd hurry up already and adapt David J. Griffiths' best seller 'Introduction to Electrodynamics' to the screen!

[Neco Kriel @AstroKriel]

@astro_sven @abcnews @galahsurvey hehehe!

Congrats by the way!

I wish I invested in the Fourier transform in 1807...

[Neco Kriel @AstroKriel]

when in doubt, consult the SI units

[Neco Kriel @AstroKriel]

C++ is the new FORTRAN,
Julia is the new IDL, and
Python is the new Bash.

Change my mind.

@astro_magnetism Classic! Also, congrats!! (ps. Best way to avoid memory errors is just to make every variable global 😉)
