Causal structures of pp-waves (2002)
Journal Article
Hubeny, V. E., & Rangamani, M. (2002). Causal structures of pp-waves. Journal of High Energy Physics, 2002(12), https://doi.org/10.1088/1126-6708/2002/12/043

We discuss the causal structure of pp-wave spacetimes using the ideal point construction outlined by Geroch, Kronheimer, and Penrose. This generalizes the recent work of Marolf and Ross, who considered similar issues for plane wave spacetimes. We add... Read More about Causal structures of pp-waves.

No horizons in pp-waves (2002)
Journal Article
Hubeny, V. E., & Rangamani, M. (2002). No horizons in pp-waves. Journal of High Energy Physics, 2002(11), https://doi.org/10.1088/1126-6708/2002/11/021

We argue that pp-wave backgrounds can not admit event horizons. We also comment on pp-wave generalizations which would admit horizons and show that there exists a black string solution which asymptotes to a five dimensional plane wave background.

Strings from quivers, membranes from moose (2002)
Journal Article
Mukhi, S., Rangamani, M., & Verlinde, E. P. (2002). Strings from quivers, membranes from moose. Journal of High Energy Physics, 2002(05), https://doi.org/10.1088/1126-6708/2002/05/023

We consider = 2 moose/quiver gauge theories corresponding to N1 D3-branes at a 2/N2 singularity in the ``large moose'' limit where N1 and N2 are scaled to infinity together. In the dual holographic description, this scaling gives rise to a maximally... Read More about Strings from quivers, membranes from moose.
