Kavli Affiliate: Feng Wang | First 5 Authors: Ying Mei, Shoulin Wei, Feng Wang, Chen Wu, Rodrigo Tobar | Summary: The Square Kilometre Array (SKA) project is an international cooperation project to build the largest radio telescope worldwide. Data processing is one of the biggest challenges of building the SKA telescope. As a distributed execution […]
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 […]
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 […]
Kavli Affiliate: Troy A. Porter | First 5 Authors: Troy A. Porter, Gudlaugur Johannesson, Igor V. Moskalenko, , | Summary: The past decade has brought impressive advances in astrophysics of cosmic rays (CRs) and multi-wavelength astronomy — thanks to the new instrumentation launched into space and built on the ground. Understanding the astrophysical backgrounds to […]
Kavli Affiliate: Brian Lantz | First 5 Authors: D. H. Shoemaker, Stefan Ballmer, Matteo Barsuglia, E. Berger, Emanuele Berti | Summary: The workshop Dawn VI: Next Generation Observatories}took place online over three days, 5-7 October, 2021. More than 200 physicists and astronomers attended to contribute to, and learn from, a discussion of next-generation ground-based gravitational-wave […]
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 […]
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 […]
Kavli Affiliate: Jing Wang | First 5 Authors: Shaofu Xu, Jing Wang, Sicheng Yi, Weiwen Zou, | Summary: Tensor analytics lays mathematical basis for the prosperous promotion of multiway signal processing. To increase computing throughput, mainstream processors transform tensor convolutions to matrix multiplications to enhance parallelism of computing. However, such order-reducing transformation produces data duplicates […]
Kavli Affiliate: Austin Joyce | First 5 Authors: James Bonifacio, Kurt Hinterbichler, Austin Joyce, Diederik Roest, | Summary: The special galileon and Dirac-Born-Infeld (DBI) theories are effective field theories of a single scalar field that have many interesting properties in flat space. These theories can be extended to all maximally symmetric spaces, where their algebras […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Laura Herold, Elisa G. M. Ferreira, Eiichiro Komatsu, , | Summary: A dark energy-like component in the early universe, known as early dark energy (EDE), is a proposed solution to the Hubble tension. Currently, there is no consensus in the literature as to whether EDE can simultaneously […]
