We perform large-scale computer simulations of an off-lattice two-dimensionalmodel of active particles undergoing a motility-induced phase separation (MIPS)to investigate the systems critical behaviour close to the critical point ofthe MIPS curve. By sampling steady-state configurations for large system sizesand performing finite size scaling analysis we provide exhaustive evidence thatthe critical behaviour of this active system belongs to the Ising universalityclass. In addition to the scaling observables that are also typical of passivesystems, we study the critical behaviour of the kinetic temperature differencebetween the two active phases. This quantity, which is always zero inequilibrium, displays instead a critical behavior in the active system which iswell described by the same exponent of the order parameter in agreement withmean-field theory.
