    The X-Ray Spectrum and Variability of NGC 4151

    We report investigation of the iron Kα line in a long (100 ks) ASCA observation of NGC 4151. This observation offers unprecedented good statistics; however, the situation is complicated by the fact that the absor...

    X-Ray Properties of High-Z Radio-Quiet Quasars: ASCA Observations

    The first-ever high energy (∼ 1–30 keV) X-ray spectra of three z ∼ 2 radio-quiet quasars (RQQs) are presented. If confirmed, the most interesting result is the marginal, but consistent, evidence for FeKaemission ...

    The ASCA Observation Campaign of SS433

    Here we present a very short review of the ASCA observation campaign of the enigmatic galactic jet system SS433. The campaign started in 1994 just after the launch, and ended in 1996. Various phases of the 162...

    Imaging Design of the Wide Field X-Ray Monitor Onboard the HETE Satellite

    The High-Energy Transient Experiment (HETE), to be launched in 1995, will study Gamma-Ray Bursts in an unprecendented wide wavelength range from Gamma-and X-ray to UV wavelengths. The X-ray range (2 to 25 keV)...

    An X-Ray All Sky Monitor for a Japanese Experimental Module on the Space Station

    We propose an X-ray all sky monitor for Japanese Experimental Module (JEM) on the space station. Considering practical circumstances, we show as a case study that the all sky monitor with slit hole cameras is ...

    Picosecond Universal Optical Fluctuation in Strongly Disordered Solids

    Propagation and scattering of a coherent wave in disordered media show inherently noise-like behavior due to random interference among multitudinously scattered waves [1]. The optical speckle and the universal...

    CCD Camera for the 60cm Telescope at Kagoshima Space Center

    A CCD detector has been developed for photometry and image detection with the 60cm reflector at Kagoshima Space Center. The structure and the manipulation of the instrument were simpified by the use of Peltier...

    Coordinated Optical-Exosat-Tenma Observations of a Burst from 2S1636-536

    During a coordinated observations of 2S1636-536 with EXOSAT, Tenma and the 1.4 metre Danish telescope at La Silla, a single burst was detected at all three observatories. The burst was bright with a peak flux ...

    Subpicosecond Accumulated Photon Echoes with Incoherent Light in Nd3+-Doped Silicate Glass

    Since the first observation of accumulated photon echoes by HESSELINK and WIERSMA [1], nearly transform-limited mode-locked pulse trains have been used as the excitation source, and the resolution times have b...
