  Using gauge-gravity duality, we extend thermodynamic studies and present
results for thermal screening masses in strongly coupled N=2* supersymmetric
Yang-Mills theory. This non-conformal theory is a mass deformation of maximally
supersymmetric N=4 gauge theory. Results are obtained for the entropy density,
pressure, specific heat, equation of state, and screening masses, down to
previously unexplored low temperatures. The temperature dependence of screening
masses in various symmetry channels, which characterize the longest length
scales over which thermal fluctuations in the non-Abelian plasma are
correlated, is examined and found to be asymptotically linear in the low
temperature regime.
