• The Abundance Of Boron In Diffuse Interstellar Clouds 

    Ritchey, A. M.; Federman, S. R.; Sheffer, Y.; Lambert, David L. (2011-02)
    We present a comprehensive survey of boron abundances in diffuse interstellar clouds from observations made with the Space Telescope Imaging Spectrograph (STIS) of the Hubble Space Telescope. Our sample of 56 Galactic sight ...
  • A detector for muon tomography: Data acquisition and preliminary results 

    Wright, Eric T. (2007-05)
    I describe the general design of the prototype particle detector constructed by the Maya Muon Tomography Group and how it can be used to e ectively \x-ray" building and ground structure in a location of interest using ...
  • A Flux Rope Network And Particle Acceleration In Three-Dimensional Relativistic Magnetic Reconnection 

    Kagan, Daniel; Milosavljevic, Milos; Spitkovsky, Anatoly (2013-09)
    We investigate magnetic reconnection and particle acceleration in relativistic pair plasmas with three-dimensional particle-in-cell simulations of a kinetic-scale current sheet in a periodic geometry. We include a guide ...
  • Surveying The Dynamic Radio Sky With The Long Wavelength Demonstrator Array 

    Lazio, T. Joseph W.; Clarke, Tracy E.; Lane, W. M.; Gross, C.; Kassim, N. E.; Ray, P. S.; Wood, D.; York, J. A.; Kerkhoff, A.; Hicks, B.; Polisensky, E.; Stewart, K.; Dalal, N. P.; Cohen, A. S.; Erickson, W. C. (2010-12)
    This paper presents a search for radio transients at a frequency of 73.8 MHz (4 m wavelength) using the all-sky imaging capabilities of the Long Wavelength Demonstrator Array (LWDA). The LWDA was a 16-dipole phased array ...
  • Two-Stream-Like Instability In Dilute Hot Relativistic Beams And Astrophysical Relativistic Shocks 

    Nakar, Ehud; Bret, Antoine; Milosavljevic, Milos (2011-09)
    Relativistic collisionless shocks are believed to be efficient particle accelerators. Nonlinear outcome of the interaction of accelerated particles that run ahead of the shock, the so-called precursor, with the unperturbed ...
