@article{Enander2015IntegratedSE, title={Integrated Sachs-Wolfe effect in massive bigravity}, author={Jonas Enander and Yashar Akrami and Edvard Mortsell and Malin Renneby and Adam R. Solomon}, journal={Physical Review D}, year={2015}, volume={91}, pages={084046} }
We study the Integrated Sachs-Wolfe (ISW) effect in ghost-free, massive bigravity, where only one metric couples to matter. We focus on the infinite-branch bigravity (IBB) model which exhibits viab ...

There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
