Query: Emergent Horizons and Causal Structures in Holography   The open string metric arises kinematically in studying fluctuations of open
string degrees of freedom on a D-brane. An observer, living on a probe D-brane,
can send signals through the spacetime by using such fluctuations on the probe,
that propagate in accordance with a metric which is conformal to the open
string metric. Event horizons can emerge in the open string metric when one
considers a D-brane with an electric field on its worldvolume. Here, we
emphasize the role of and investigate, in details, the causal structure of the
resulting open string event horizon and demonstrate, among other things, its
close similarities to an usual black hole event horizon in asymptotically
AdS-spaces. To that end, we analyze relevant geodesics, Penrose diagrams and
various causal holographic observables for a given open string metric. For
analytical control, most of our calculations are performed in an asymptotically
AdS$_3$-background, however, we argue that the physics is qualitatively the
same in higher dimensions. We also discuss how this open string metric arises
from an underlying D-brane configuration in string theory.
