I will report on recent joint work with Laura Fredrickson, Rafe Mazzeo and Jan Swoboda, in which we study the asymptotics of the Hitchin metric on moduli spaces of parabolic Higgs bundles. These give rise to real 4-dimensional and complete hyperkähler metrics when considered e.g. on the 4-punctured sphere. We will discuss the question (raised by Hitchin and others) if the 4-punctured sphere moduli space is an ALG gravitational instanton.
