| « Giant structures and stringy inflation » |
|
N. Itzhaki |
| Many stringy models of inflation suffer from the overshoot problem. We discuss a particularly efficient resolution to the problem and show that this resolution predicts the existence of giant spherically symmetric overdense regions with radius of about 110 Mpc. We discuss possible effects these structures can have on the peculiar velocity and CMB. |
