"Flat space limit of higher-spin Cardy formula";
Physical Review D, 91 (2015), 024044.

In this paper I derive the flat space limit of the modified Cardy formula associated with inner horizons and show that it reproduces the correct Galilean conformal field theory counting of flat space cosmology microstates. l also determine the entropy of flat space cosmologies in flat space chiral gravity in this way. In addition, I derive a Cardy-like expression for flat space cosmologies with spin-3 charges and, thus, give a prediction for the corresponding Galilean conformal field theory counting of flat space cosmology microstates with spin-3 charges.
