Kavli Affiliate: Daniel Holz | First 5 Authors: Pierre Auclair, David Bacon, Tessa Baker, Tiago Barreiro, Nicola Bartolo | Summary: The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early universe and particle […]
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 […]
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; […]
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 […]
Kavli Affiliate: Alireza Marandi | First 5 Authors: Luis Costa, Zhongwen Zhan, Alireza Marandi, , | Summary: Simultaneously sensing and resolving the position of measurands along an optical fiber enables numerous opportunities, especially for application in environments where massive sensor deployment is not feasible. Despite significant progress in techniques based on round-trip time-of-flight measurements, the […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: K. R. Ferguson, A. J. Anderson, N. Whitehorn, P. A. R. Ade, M. Archipley | Summary: Ultralight axion-like particles (ALPs) are compelling dark matter candidates because of their potential to resolve small-scale discrepancies between $Lambda$CDM predictions and cosmological observations. Axion-photon coupling induces a polarization rotation in linearly […]

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: BICEP/Keck Collaboration, :, P. A. R. Ade, Z. Ahmed, M. Amiri | Summary: For the past decade, the BICEP/Keck collaboration has been operating a series of telescopes at the Amundsen-Scott South Pole Station measuring degree-scale $B$-mode polarization imprinted in the Cosmic Microwave Background (CMB) by primordial gravitational […]
Kavli Affiliate: Clarence L. Chang | First 5 Authors: Thomas Cecil, Clarence L. Chang, Shannon M. Duff, Dale Li, Rupak Mahapatra | Summary: Superconducting sensors are a key enabling technology for many HEP experiments with advances in sensor capabilities leading directly to expanded science reach. The unique materials and processes required for the fabrication of […]
Kavli Affiliate: Robert M. Wald | First 5 Authors: Kartik Prabhu, Gautam Satishchandran, Robert M. Wald, , | Summary: Infrared (IR) divergences arise in scattering theory with massless fields and are manifestations of the memory effect. There is nothing singular about states with memory, but they do not lie in the standard Fock space. IR […]
