  • Gamma-ray waveguides

    ” Applied Physics Letters 92, 1 2008

    "A new approach to gamma-ray optics provides flat and curved waveguides for 122 keV gamma rays and could be useful up to a few mega-electron-volts. Instead of using shallow angle reflection, which typically implies focal lengths of around 10 m, D M Tournear and colleagues at Los Alamos National Laboratory have used multilayer gold–palladium and polymer films to get focal lengths an order of magnitude smaller. This novel optics could find use in fields ranging from astrophysics to medical…

  • X-ray Bursts in Neutron Star and Black Hole Binaries: Detections and Upper Limits

    The Astrophysical Journal

    Certain theories speculate that black holes may be composed of forms of matter possessing a surface. We calculate a limit ruling out the existence of these surfaces, thereby giving further evidence to the existence of black holes.

  • Long Term X-ray Variability in Circinus X-1

    The Astrophysical Journal

    We present an analysis of long-term X-ray monitoring observations of Circinus X-1 (Cir X-1) made with four different instruments: Vela 5B, Ariel 5 all-sky monitor (ASM), Ginga ASM, and RXTE ASM, over the course of more than 30 yr.
