Kavli Affiliate: Elise Jennings | First 5 Authors: Elise Jennings, , , , | Summary: The velocity divergence power spectrum is a key ingredient in modelling redshift space distortion effects on quasi-linear and nonlinear scales. We present an improved model for the z=0 velocity divergence auto and cross power spectrum which was originally suggested by […]
Kavli Affiliate: Alireza Marandi | First 5 Authors: Alireza Marandi, Nick C. Leindecker, Konstantin L. Vodopyanov, Robert L. Byer, | Summary: True random number generators (RNGs) are desirable for applications ranging from cryptogra- phy to computer simulations. Quantum phenomena prove to be attractive for physical RNGs due to their fundamental randomness and immunity to attack […]
Kavli Affiliate: Daniel Holz | First 5 Authors: Hsin-Yu Chen, Daniel E. Holz, , , | Summary: Using the observed rate of short-duration gamma-ray bursts (GRBs) it is possible to make predictions for the detectable rate of compact binary coalescences in gravitational-wave detectors. These estimates rely crucially on the growing consensus that short gamma-ray bursts […]
Kavli Affiliate: Homer Neal | First 5 Authors: Z. Akopov, Silvia Amerio, David Asner, Eduard Avetisyan, Olof Barring | Summary: Data from high-energy physics (HEP) experiments are collected with significant financial and human effort and are mostly unique. An inter-experimental study group on HEP data preservation and long-term analysis was convened as a panel of […]
Kavli Affiliate: Nathan S. Lewis | First 5 Authors: Guillem Anglada-Escudé, Peter Plavchan, Sean Mills, Peter Gao, Edgardo García-Berríos | Summary: We present a method to optimize absorption cells for precise wavelength calibration in the near-infrared. We apply it to design and optimize methane isotopologue cells for precision radial velocity measurements in the K band. […]
Kavli Affiliate: Craig J. Hogan | First 5 Authors: Craig J. Hogan, , , , | Summary: A model quantum system is proposed to describe position states of a massive body in flat space on large scales, excluding all standard quantum and gravitational degrees of freedom. The model is based on standard quantum spin commutators, […]
Kavli Affiliate: Mark Bowick | First 5 Authors: Zhenwei Yao, Mark Bowick, Xu Ma, Rastko Sknepnek, | Summary: If an inextensible thin sheet is adhered to a substrate with a negative Gaussian curvature it will experience stress due to geometric frustration. We analyze the consequences of such geometric frustration using analytic arguments and numerical simulations. […]
Kavli Affiliate: Robert A. Cameron | First 5 Authors: Markos Trichas, Paul J. Green, John D. Silverman, Tom Aldcroft, Wayne Barkhouse | Summary: From optical spectroscopy of X-ray sources observed as part of ChaMP, we present redshifts and classifications for a total of 1569 Chandra sources from our targeted spectroscopic follow up using the FLWO, […]
Kavli Affiliate: Sarah Church | First 5 Authors: Matthew Sieth, Sarah Church, Judy M. Lau, Patricia Voll, Todd Gaier | Summary: We report on the development of W-band (75-110 GHz) heterodyne receiver technology for large-format astronomical arrays. The receiver system is designed to be both mass-producible, so that the designs could be scaled to thousands […]
Kavli Affiliate: Keith Schwab | First 5 Authors: , , , , | Summary: Graphene is a material with remarkable electronic properties and exceptional thermal transport properties near room temperature, which have been well examined and understood. However at very low temperatures the thermodynamic and thermal transport properties are much less well explored and somewhat […]
