Publication: We have several planned papers. The two most relevant are:
"First results from exascale simulations of AGN jet-driven magnetized plasma turbulence in idealized cluster simulations" by P. Grete, B.W. O'Shea, F.W. Glines, D. Prasad, and B. Wibking (to be submitted to The Astrophysical Journal)
"Turbulence statistics and energy transport in exascale simulations of AGN jet-driven magnetized plasma turbulence in idealized cluster simulations" by P. Grete, B.W. O'Shea, F.W. Glines, D. Prasad, and B. Wibking (to be submitted to The Astrophysical Journal)Presenters
