@article{Mgevand2013StabilityOC, title={Stability of cosmological deflagration fronts}, author={Ariel M{\'e}gevand and Federico Agust'in Membiela}, journal={Physical Review D}, year={2013}, volume={89}, pages={103507} }

In a cosmological first-order phase transition, bubbles of the stable phase nucleate and expand in the supercooled metastable phase. In many cases, the growth of bubbles reaches a stationary state, with bubble walls propagating as detonations or deflagrations. However, these hydrodynamical solutions may be unstable under corrugation of the interface. Such instability may drastically alter some of the cosmological consequences of the phase transition. Here, we study the hydrodynamical stability…
