The Gromov limit for vortex moduli spaces

We generalize the descriptions of vortex moduli spaces in [4] to more than one section with adiabatic constant s. The moduli space is topologically independent of s but is not compact with respect to C-infinity topology. Following [17], we construct a Gromov limit for vortices of fixed energy, and attempt to compactify the moduli space via bubble trees with possibly conical bubbles (or raindrops).
