Notes: | IAS Conference on Cosmology since Einstein. IAS title: Talk 12: 'Searching for Remnant String Loops by Microlensing'. Abstract: Superstring loops form by intercommutation of horizon‐crossing superstrings. The loops are captured and accreted during galaxy formation and a population of these loops resides within the galaxy today. A loop can lens background stars generating a unique signature of repeated, achromatic flux doubling events. The Large Synoptic Survey Telescope is a large aperture, wide field telescope that is able to image faint astronomical objects across the sky. This instrument can potentially probe the range of string tensions $10^{‐13.5} < G \mu/c^2 < 10^{‐9.5}$ which corresponds to characteristic energies $\sim 10^{12} ‐ 10^{14}$ GeV. Event rates are discussed. Duration: 40 min. |
