Supersymmetric Intersecting Branes on the Waves

Understand

We construct a general family of supersymmetric solutions in time- and space-dependent wave backgrounds in general supergravity theories describing single and intersecting p-branes embedded into time-dependent dilaton-gravity plane waves of an arbitrary (isotropic) profile, with the brane world-volume aligned parallel to the propagation direction of the wave.

• We discuss how many degrees of freedom we have in the solutions.
• We also propose that these solutions can be used to describe higher-dimensional time-dependent "black holes", and discuss their property briefly.
