TL;DR
This paper studies bubble collisions in first order phase transitions, revealing that under certain conditions, they produce long-lived scalar field quasilumps with localized energy and scalar wave radiation.
Contribution
It introduces the formation of long-lived scalar quasilumps from bubble collisions during first order phase transitions, supported by numerical simulations.
Findings

Energy remains localized with pulsating density.
Scalar wave radiation accompanies quasilump formation.
Abstract
We investigated the bubble collisions during the first order phase transitions. Numerical results indicate that within the certain range of parameters the collision of two bubbles leads to formation of separate relatively long-lived quasilumps - configurations filled with scalar field oscillating around the true vacuum state. Energy is perfectly localized, and density is slightly pulsating around its maximum. This process is accompanied by radiation of scalar waves.
