  We determine the universal location of the Yang-Lee edge singularity in the
entire relevant domain of spatial dimensions $1\le d \le 4$ for the Ising
universality class. To that end, we present analytical results for $d=1,2,4$
and near four dimensions. For $d=3$ and a set of fractional dimensions, we
perform numerical calculations using a systematic Functional Renormalization
Group approach.
