摘要：

We investigate a class of cylindrically symmetric inhomogeneous.-dust spacetimes which have a regular axis and some zero expansion component. For Lambda not equal 0, we obtain new exact solutions to the Einstein equations and show that they are unique, within that class. For Lambda = 0, we recover the SenovillaVera metric and show that it can be locally matched to an Einstein-Rosen type of exterior. Finally, we explore some consequences of the matching, such as trapped surface formation and gravitational radiation in the exterior.
