Magnetar Driven Bubbles and the Origin of Collimated Outflows from GRBs
N. Bucciantini, E. Quataert, J. Arons +2
We model the interaction between the wind from a newly formed rapidly rotating magnetar and the surrounding progenitor. In the first few seconds after core collapse the magnetar in…
Representing complex data using localized principal components with application to astronomical data
Jochen Einbeck, Ludger Evers, Coryn Bailer-Jones
Often the relation between the variables constituting a multivariate data space might be characterized by one or more of the terms: ``nonlinear'', ``branched'', ``disconnected'', `…
Large Magnetoresistance in Co/Ni/Co Ferromagnetic Single Electron Transistors
R. S. Liu, H. Pettersson, L. Michalak +3
We report on magnetotransport investigations of nano-scaled ferromagnetic Co/Ni/Co single electron transistors. As a result of reduced size, the devices exhibit single electron tra…
Spectropolarimetry of Compton-thin Seyfert 2s
S. L. Lumsden, D. M. Alexander, J. H. Hough
We present new spectropolarimetry of a sample of nearby Compton-thin Seyfert 2 galaxies (ie those with N_H<10^23 cm^-2). We show that the detection rate of scattered broad Halpha i…
Single-Particle Excitations in a Two-Dimensional Strong-Coupling Superconductor
D. W. Hess, J. J. Deisz, J. W. Serene
We present calculations of the single-particle excitation spectrum for a 2D strong-coupling superconductor in a conserving approximation. Spectral weight at low frequency is substa…
