Two Candidate KH 15D-like Systems from the Zwicky Transient Facility

Kavli Affiliate: Subo Dong | First 5 Authors: Wei Zhu, Klaus Bernhard, Fei Dai, Min Fang, J. J. Zanazzi | Summary: KH 15D contains a circumbinary disk that is tilted relative to the orbital plane of the central binary. The precession of the disk and the orbital motion of the binary together produce rich phenomena […]

Formal Analysis of Lending Pools in Decentralized Finance

Kavli Affiliate: James Chiang | First 5 Authors: Massimo Bartoletti, James Chiang, Tommi Junttila, Alberto Lluch Lafuente, Massimiliano Mirelli | Summary: Decentralised Finance (DeFi) applications constitute an entire financial ecosystem deployed on blockchains. Such applications are based on complex protocols and incentive mechanisms whose financial safety is hard to determine. Besides, their adoption is rapidly […]

Nested sampling for physical scientists

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Greg Ashton, Noam Bernstein, Johannes Buchner, Xi Chen, Gábor Csányi | Summary: We review Skilling’s nested sampling (NS) algorithm for Bayesian inference and more broadly multi-dimensional integration. After recapitulating the principles of NS, we survey developments in implementing efficient NS algorithms in practice in high-dimensions, including methods […]
