Cosmic Reionization on Computers: Physical Origin of Long Dark Gaps in Quasar Absorption Spectra

Posted by Chicago

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Nickolay Y. Gnedin, , , , | Summary: I explore the properties of "dark gaps" – regions in quasar absorption spectra without significant transmission – with several simulations from the Cosmic Reionization On Computers (CROC) project. CROC simulations in largest available boxes (120 cMpc) come close […]

Investigation of CMB constraints for dark matter-helium scattering

Posted by Chicago

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Kimberly K. Boddy, Gordan Krnjaic, Stacie Moltner, , | Summary: We study dark matter-helium scattering in the early Universe and its impact on constraints from cosmic microwave background (CMB) anisotropy measurements. We describe possible theoretical frameworks for dark matter-nucleon interactions via a scalar, pseudoscalar, or vector mediator; […]

A Weakly Supervised Propagation Model for Rumor Verification and Stance Detection with Multiple Instance Learning

Posted by Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Ruichao Yang, Jing Ma, Hongzhan Lin, Wei Gao, | Summary: The diffusion of rumors on microblogs generally follows a propagation tree structure, that provides valuable clues on how an original message is transmitted and responded by users over time. Recent studies reveal that rumor detection and stance […]
