Kavli Affiliate: Craig J. Hogan | First 5 Authors: Craig J. Hogan, , , , | Summary: A theory of position of massive bodies is proposed that results in an observable quantum behavior of geometry at the Planck scale, $t_P$. Departures from classical world lines in flat spacetime are described by Planckian noncommuting operators for […]
Kavli Affiliate: Richard Kessler | First 5 Authors: Richard Kessler, Alex Conley, Saurabh Jha, Stephen Kuhlmann, | Summary: We have publicly released a blinded mix of simulated SNe, with types (Ia, Ib, Ic, II) selected in proportion to their expected rate. The simulation is realized in the griz filters of the Dark Energy Survey (DES) […]
Kavli Affiliate: Tom Chang | First 5 Authors: Sunny W. Y. Tam, Tom Chang, Paul M. Kintner, Eric M. Klatt, | Summary: Rank-Ordered Multifractal Analysis (ROMA), a recently developed technique that combines the ideas of parametric rank ordering and one parameter scaling of monofractals, has the capabilities of deciphering the multifractal characteristics of intermittent fluctuations. […]
Kavli Affiliate: Catherine Grant | First 5 Authors: Eric D. Miller, Marshall Bautz, Catherine Grant, Ryan Hickox, Mark Brodwin | Summary: Galaxy groups are key tracers of galaxy evolution, cluster evolution, and structure formation, yet they are difficult to study at even moderate redshift. We have undertaken a project to observe a flux-limited sample of […]
Kavli Affiliate: Alan Levine | First 5 Authors: Martin Durant, Remon Cornelisse, Ron Remillard, Alan Levine, | Summary: Regular observations by the All Sky Monitor aboard the Rossi X-ray Timing Explorer satellite have yielded well-sampled light-curves with a time baseline of over ten years. We find that up to eight of the sixteen brightest persistent […]
Kavli Affiliate: Ralf Heilmann | First 5 Authors: Herman L. Marshall, Ralf Heilmann, Norbert Schulz, Kendrah Murphy, | Summary: We developed an instrument design capable of measuring linear X-ray polarization over a broad-band using conventional spectroscopic optics. A set of multilayer-coated flats reflects the dispersed X-rays to the instrument detectors. The intensity variation with position […]
Kavli Affiliate: Tomiyoshi Haruyama | First 5 Authors: The J-Parc Ucn Taskforce, :, Tomokazu Aso, Masatoshi Futakawa, Tomiyoshi Haruyama | Summary: Discussions in the taskforce meetings in the period of Jan.-Mar. 2009 on the technical possibility of the ultracold neutron (UCN) source at the Japan Proton Accelerator Research Complex (J-PARC) is summarized. | Search Query: […]
Kavli Affiliate: Robert M. Wald | First 5 Authors: Robert M. Wald, , , , | Summary: The motion of sufficiently small body in general relativity should be accurately described by a geodesic. However, there should be “gravitational self-force” corrections to geodesic motion, analogous to the “radiation reaction forces” that occur in electrodynamics. It is […]
Kavli Affiliate: Carlos Wagner | First 5 Authors: Patrick Draper, Tao Liu, Carlos E. M. Wagner, , | Summary: We analyze the Tevatron reach for neutral Higgs bosons in the Minimal Supersymmetric Standard Model (MSSM), using current exclusion limits on the Standard Model Higgs. We study four common benchmark scenarios for the soft supersymmetry-breaking parameters […]
Kavli Affiliate: Thomas M. Crawford | First 5 Authors: Samir Garzon, Richard A. Webb, Mark Covington, Shehzaad Kaka, Thomas M. Crawford | Summary: In large magnetoresistance devices spin torque-induced changes in resistance can produce GHz current and voltage oscillations which can affect magnetization reversal. In addition, capacitive shunting in large resistance devices can further reduce […]
