Query: The speed of a biased random walk on a Galton-Watson tree is analytic   We prove that the speed of a biased random walk on a supercritical
Galton-Watson tree conditioned to survive is analytic within the ballistic
regime. This extends the previous work arXiv:1906.07913 in which it was shown
that the speed is differentiable within the range of bias for which a central
limit theorem holds.
