Abstract: We present results on the Omega baryon electromagnetic form factors usingN f= 2 + 1 dynamical domain-wall fermion configurations corresponding to a pionmass of about 330 MeV. We construct appropriate sequential sources for thedetermination of the two dominant form factors GE0 and GM1 as well as asequential source that isolates the subdominant electric quadrupole form factorGE2. We calculate the Omega baryon magnetic moment, mu omega, and electriccharge radius, ^2, and compare to experiment, for the case of mu omega,and to other lattice calculations.
