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: Jos Zwanikken | First 5 Authors: Jos Zwanikken, René van Roij, , , | Summary: Within a modified Poisson-Boltzmann theory we study the effect of Bjerrum pairs on the typical length scale $1/bar{kappa}$ over which electric fields are screened in electrolyte solutions, taking into account a simple association-dissociation equilibrium between free ions and […]
Kavli Affiliate: Karen L. Byrum | First 5 Authors: Robert G. Wagner, Karen L. Byrum, Mayly Sanchez, Alexandre V. Vaniachine, Oswald Siegmund | Summary: We advocate support of research aimed at developing alternatives to the photomultiplier tube for photon detection in large astroparticle experiments such as gamma-ray and neutrino astronomy, and direct dark matter detectors. […]
Kavli Affiliate: Ralf Heilmann | First 5 Authors: Norbert S. Schulz, Glenn Allen, Mark W. Bautz, Claude C. Canizares, John Davis | Summary: Low-mass pre-main sequence (PMS) stars are strong and variable X-ray emitters, as has been well established by EINSTEIN and ROSAT observatories. It was originally believed that this emission was of thermal nature […]
Kavli Affiliate: Mark Schattenburg | First 5 Authors: Norbert S. Schulz, Glenn Allen, Mark W. Bautz, Claude C. Canizares, John Davis | Summary: Understanding the origins and distribution of matter in the Universe is one of the most important quests in physics and astronomy. Themes range from astro-particle physics to chemical evolution in the Galaxy […]
Kavli Affiliate: David Weitz | First 5 Authors: David Issadore, Katherine J. Humphry, Keith A. Brown, Lori Sandberg, David Weitz | Summary: We present a technique to locally and rapidly heat water drops in microfluidic devices with microwave dielectric heating. Water absorbs microwave power more efficiently than polymers, glass, and oils due to its permanent […]
Kavli Affiliate: Jos Zwanikken | First 5 Authors: Jos Zwanikken, Joost de Graaf, Markus Bier, René van Roij, | Summary: We calculate ion distributions near a planar oil-water interface within non-linear Poisson-Boltzmann theory, taking into account the Born self-energy of the ions in the two media. For unequal self-energies of cations and anions, a spontaneous […]
Kavli Affiliate: Stuart Marshall | First 5 Authors: Željko Ivezić, Steven M. Kahn, J. Anthony Tyson, Bob Abel, Emily Acosta | Summary: (Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a single wide-deep-fast sky survey, […]
