    • X-ray periodicities in sources observed by the RXTE ASM 

      Shivamoggi, Vasudha B (Massachusetts Institute of Technology, 2005)
      The X-ray intensities measured from 230 X-ray sources observed by the RXTE All-Sky Monitor (ASM) were analyzed for periodic behavior. The ASM has been observing sources for nine years in the 1.5-12 keV energy range. In ...
    • X-ray power density spectra of black hole binaries : a new deadtime model for the RXTE PCA 

      Wei, Dennis (Massachusetts Institute of Technology, 2006)
      The power density spectrum is an essential tool for determining the frequency content of X-ray radiation from astronomical sources. For neutron star systems, power density spectra reveal coherent oscillations for those ...
    • Xmess--a graphical voice-mail interface 

      Berman, Lorne David (Massachusetts Institute of Technology, 1990)
    • Zero sound modes in the AdS/CFT correspondence 

      Roxlo, Thomas (Thomas Q.) (Massachusetts Institute of Technology, 2012)
      We examine the effects of zero sound wave excitations of charged fermion species living around the charged black hole of an AdS/CFT spacetime. In particular, we show that these bulk modes cause corresponding singularities ...
