Query: The extremal process of a cascading family of branching Brownian motion   We study the asymptotic behaviour of the extremal process of a cascading
family of branching Brownian motions. This is a particle system on the real
line such that each particle has a type in addition to his position. Particles
of type $1$ move on the real line according to Brownian motions and branch at
rate $1$ into two children of type $1$. Furthermore, at rate $\alpha$, they
give birth to children too of type $2$. Particles of type $2$ move according to
standard Brownian motion and branch at rate $1$, but cannot give birth to
descendants of type $1$. We obtain the asymptotic behaviour of the extremal
process of particles of type $2$.
