A spectral Galerkin method for the coupled Orr-Sommerfeld and induction equations for free-surface MHD

Posted by klaurent Chicago

Kavli Affiliate: Robert Rosner | Summary:We develop and test spectral Galerkin schemes to solve the coupled Orr-Sommerfeld (OS) and induction equations for parallel, incompressible MHD in free-surface and fixed-boundary geometries. The schemes’ discrete bases consist of Legendre internal shape functions, supplemented with nodal shape functions for the weak imposition of the stress and insulating boundary […]

Magnetic Flux Diffusion and Expulsion with Thin Conducting Sheets

Posted by klaurent MIT

Kavli Affiliate: John Belcher | Summary:We present visualizations of the diffusion and expulsion of magnetic flux for thin conducting sheets, both stationary and moving, including representations of the eddy currents and of the associated magnetic fields. Such visualizations can play an important role in making the abstract mathematics of eddy current phenomena more understandable from […]

Conduction Effect of Thermal Radiation in a Metal Shield Pipe in a Cryostat for a Cryogenic Interferometric Gravitational Wave Detector

Posted by klaurent Tokyo

Kavli Affiliate: Tomiyoshi Haruyama | Summary:A large heat load caused by thermal radiation through a metal shield pipe was observed in a cooling test of a cryostat for a prototype of a cryogenic interferometric gravitational wave detector. The heat load was approximately 1000 times larger than the value calculated by the Stefan-Boltzmann law. We studied […]

Radio Detection of Neutrinos from Behind a Mountain

Posted by klaurent Tokyo

Kavli Affiliate: Kai Martens | Summary:We explore the sensitivity of a neutrino detector employing strongly directional high gain radio antennae to detect the conversion of neutrinos above $10^16$ eV in a mountain or the earth crust. The directionality of the antennae will allow both, the low threshold and the suppression of background. This technology would […]

HiRes Estimates and Limits for Neutrino Fluxes at the Highest Energies

Posted by klaurent Tokyo

Kavli Affiliate: Kai Martens | Summary:The High Resolution Fly’s Eye Experiment (HiRes) measures cosmic rays (CR) at the highest energies using the air fluorescence technique. As data taking on the Dugway Proving Grounds in Western Utah is finished, the HiRes data are relevant for cosmogenic neutrinos in two different ways. We first use our best […]

Current status of Japanese detectors

Posted by klaurent Tokyo

Kavli Affiliate: Tomiyoshi Haruyama | Summary:Current status of TAMA and CLIO detectors in Japan is reported in this article. These two interferometric gravitational-wave detectors are being developed for the large cryogenic gravitational wave telescope (LCGT) which is a future plan for detecting gravitational wave signals at least once per year. TAMA300 is being upgraded to […]

The Use of Weighting in Periodicity Searches in All-Sky Monitor Data: Applications to the GLAST LAT

Posted by klaurent Stanford

Kavli Affiliate: Richard Dubois | Summary:The light curves produced by all-sky monitors, such as the Rossi X-ray Timing Explorer All-Sky Monitor and the Swift Burst Alert Telescope (BAT), generally have non-uniform error bars. In searching for periodic modulation in this type of data using power spectra it can be important to use appropriate weighting of […]
