SUMMARY:A  Deferred Correction Coupling Strategy for Cosmological Simulati
 ons
DESCRIPTION:Workshop\nDiversity, Education, Hot Topics, Workshop Reg Pass\
 n\nA  Deferred Correction Coupling Strategy for Cosmological Simulations\n
 \nSexton\n\nWe present a strategy for coupling the equations of baryonic g
 as dynamics to those for radiative heating and cooling in the context of N
 yx, an N-body + gas dynamics code for large-scale cosmological simulations
 . The radiative and advective processes have differing time scales. To avo
 id Strang splitting errors, we couple the processes with a simplified spec
 tral deferred correction strategy. Preliminary results indicate that the i
 mproved coupling strategy improves stability and reduces the cost of integ
 rating the heating and cooling terms for our Lyman-alpha forest test case.
