This September, Iām joining the Institute for Advanced Study as a NASA Hubble Fellow and Member, working on turbulence and magnetic fields in astrophysical plasmas.
With Raphael Skalidis, Aris Tritsis, and Philip F. Hopkins, we show how the way turbulence is driven changes the balance of kinetic and magnetic energy. Published in Astronomy & Astrophysics, 713, A7.
My graduate-level notes on fluid theory, turbulence, and dynamos in magnetized plasmas are now available to read and download.
Published in The Astrophysical Journal Letters, 1004, L9. I show how instabilities in supernova shells generate incompressible turbulence, connecting small-scale structure to the turbulence cascade in our Galaxy.
With Max Sokolova, Khush Negandhi, and Bart Ripperda, we derive an exact reformulation of compressible NavierāStokes flow in Schrƶdinger-type variables. The paper is available on arXiv.
Our study of cosmic-ray and plasma coupling, led by Matt Sampson, is now published in The Astrophysical Journal. Congratulations, Matt!
Our study of relativistic cosmic-ray fluids and plasma coupling, led by Princeton graduate student Matt Sampson, is now available on arXiv.
The key spectral results from the 10k simulation is published in Nature Astronomy!
There is an unruly amount of u and b alignment in the 10k simulations, which I think is strongly related to the dynamo saturation. We have submitted direct tests the dynamical alignment theory to PRL, showing that alignment is even more wide-spread than dynamical alignment would predict.
Neco has done some fantastic work on the supersonic turbulent dynamo, showing for the first time the signficant changes to the Kasantsev spectrum!
