A new mechanism of black hole formation in a first order phase transition is proposed. In vacuum bubble collisions the interaction of bubble walls leads to the formation of nontrivial vacuum configuration. The consequent collapse of this vacuum configuration induces the black hole formation with high probability. Observational constraints on the spectrum of primordial black holes allow to obtain new nontrivial restrictions on parameters of inflation models with first order phase transitions.

Particle Production via Rippled Bubble Walls
A rippled bubble wall produces heavy particles resonantly when the momentum transfer matches the ripple frequency, potentially raising dark-matter abundance by orders of magnitude.

Numerical simulations of primordial black hole formation via delayed first-order phase transitions
Spherically symmetric numerical relativity shows false-vacuum domains from delayed first-order phase transitions form type B (baby-universe) or type A (direct-collapse) primordial black holes, separated by a robust t_...

Complementary Probes of Warped Extra Dimension: Colliders, Gravitational Waves and Primordial Black Holes from Phase Transitions
In Randall-Sundrum warped extra dimension models, the supercooled radion phase transition can form primordial black holes that account for all of dark matter for IR scales 10 TeV to 10^4 TeV, with correlated gravitati...

Numerical simulations of density perturbation and gravitational wave production from cosmological first-order phase transition
3D simulations of cosmological first-order phase transitions find density perturbation spectra with k^3 and k^{-1.5} slopes and GW spectra with k^3 and k^{-2}, confirming slow transitions can produce PBHs.

Super-exponential Primordial Black Hole Production via Delayed Vacuum Decay
PBH abundance from delayed vacuum decay follows f_pbh ≈ M exp(-Q exp(-S3(Tp)/Tp)), so S3(Tp)/Tp super-exponentially controls how many black holes form.
