Kavli Affiliate: Robert A. Cameron | First 5 Authors: Martin C. Weisskopf, Thomas L. Aldcroft, Robert A. Cameron, Poshak Gandhi, Cédric Foellmi | Summary: Before the official first-light images, the Chandra X-Ray Observatory obtained an X-ray image of the field to which its focal plane was first exposed. We describe this historic observation and report […]
Kavli Affiliate: Clarence Chang | First 5 Authors: CDMS Collaboration, , , , | Summary: The Cryogenic Dark Matter Search (CDMS-II) employs low-temperature Ge and Si detectors to seek Weakly Interacting Massive Particles (WIMPs) via their elastic scattering interactions with nuclei. Simultaneous measurements of both ionization and phonon energy provide discrimination against interactions of background […]
Kavli Affiliate: George M. Whitesides | First 5 Authors: Eric Lauga, Willow R. DiLuzio, George M. Whitesides, Howard A. Stone, | Summary: Near a solid boundary, E. coli swims in clockwise circular motion. We provide a hydrodynamic model for this behavior. We show that circular trajectories are natural consequences of force-free and torque-free swimming, and […]
Kavli Affiliate: Peter G. Ford | First 5 Authors: Anil Bhardwaj, Ronald F. Elsner, J. Hunter Waite, Jr., G. Randall Gladstone, Thomas E. Cravens | Summary: Using the Advanced CCD Imaging Spectrometer (ACIS), the Chandra X-ray Observatory (CXO) observed the Saturnian system for one rotation of the planet (~37 ks) on 20 January, 2004, and […]
Kavli Affiliate: Keith Schwab | First 5 Authors: Salman Habib, Tanmoy Bhattacharya, Andrew Doherty, Benjamin Greenbaum, Asa Hopkins | Summary: The vast majority of the literature dealing with quantum dynamics is concerned with linear evolution of the wave function or the density matrix. A complete dynamical description requires a full understanding of the evolution of […]

Kavli Affiliate: Peter G. Ford | First 5 Authors: Anil Bhardwaj, Ronald F. Elsner, J. Hunter Waite Jr, G. Randall Gladstone, Thomas E. Cravens | Summary: Saturn was observed by Chandra ACIS-S on 20 and 26-27 January 2004 for one full Saturn rotation (10.7 hr) at each epoch. We report here the first observation of […]
Kavli Affiliate: P. C. Joss | First 5 Authors: A. Majczyna, J. Madej, P. C. Joss, A. Rozanska, | Summary: This paper presents the set of plane-parallel model atmosphere equations for a very hot neutron star (X-ray burst source). The model equations assume both hydrostatic and radiative equilibrium, and the equation of state of an […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: R. S. Bussmann, W. L. Holzapfel, C. L. Kuo, , | Summary: We report measurements of the millimeter wavelength brightness fluctuations produced by the atmosphere above the South Pole made with the Arcminute Cosmology Bolometer Array Receiver (ACBAR). The data span the 2002 Austral winter during which […]
Kavli Affiliate: Luca Grandi | First 5 Authors: R. Brunetti, E. Calligarich, M. Cambiaghi, F. Carbonara, F. Cavanna | Summary: The WARP programme for dark matter search with a double phase argon detector is presented. In such a detector both excitation and ionization produced by an impinging particle are evaluated by the contemporary measurement of […]
