Statistics and Topology of Fluctuating Ribbons

Kavli Affiliate: L. Mahadevan | First 5 Authors: Ee Hou Yong, Farisan Dary, Luca Giomi, L. Mahadevan, | Summary: Ribbons are a class of slender structures whose length, width, and thickness are widely separated from each other. This scale separation gives a ribbon unusual mechanical properties in athermal macroscopic settings, e.g. it can bend without […]

Sensitivity of the Roman Coronagraph Instrument to Exozodiacal Dust

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Ewan S Douglas, John Debes, Bertrand Mennesson, Bijan Nemati, Jaren Ashcraft | Summary: Exozodiacal dust, warm debris from comets and asteroids in and near the habitable zone of stellar systems, reveals the physical processes that shape planetary systems. Scattered light from this dust is also a source […]

Primordial Black Hole Formation in Non-Minimal Curvaton Scenario

Kavli Affiliate: Misao Sasaki | First 5 Authors: Shi Pi, Misao Sasaki, , , | Summary: In the curvaton scenario, the curvature perturbation is generated after inflation at the curvaton decay, which may have a prominent non-Gaussian effect. For a model with a non-trivial kinetic term, an enhanced curvature perturbation on a small scale can […]

Primordial black hole formation from massless scalar isocurvature

Kavli Affiliate: Misao Sasaki | First 5 Authors: Chul-Moon Yoo, Tomohiro Harada, Shin’ichi Hirano, Hirotada Okawa, Misao Sasaki | Summary: We numerically study the primordial black hole (PBH) formation by an isocurvature perturbation of a massless scalar field on super Hubble scales in the radiation-dominated universe. As a first step we perform simulations of spherically […]
