We present high-resolution radio and X-ray studies of the composite supernova remnant G11.2-0.3. Using archival VLA data, we perform radio spectral tomography to measure for the fi…
Asymmetric Supernovae from Magneto-Centrifugal Jets
J. Craig Wheeler, David L. Meier, James R. Wilson
Strong toroidal magnetic fields generated in stellar collapse can generate magneto-centrifugal jets in analogy to those found in simulations of black hole accretion and explain why…
15 Years Going Steady - Timing the Magnetar 1E 1841-045

We report on a long-term monitoring campaign of 1E 1841-045, the 12-s anomalous X-ray pulsar and magnetar candidate at the center of the supernova remnant Kes 73. We have obtained…
The creation of large photon-number path entanglement conditioned on photodetection
Pieter Kok, Hwang Lee, Jonathan P. Dowling
Large photon-number path entanglement is an important resource for enhanced precision measurements and quantum imaging. We present a general constructive protocol to create any lar…
Cosmic Microwave Background Anisotropy Measurement From Python V
K. Coble, S. Dodelson, M. Dragovan +5
We analyze observations of the microwave sky made with the Python experiment in its fifth year of operation at the Amundsen-Scott South Pole Station in Antarctica. After modeling t…
Chandra Detection of a TypeII Quasar at z=3.288
Daniel Stern, Edward C. Moran, Alison L. Coil +16
We report on observations of a TypeII quasar at redshift z=3.288, identified as a hard X-ray source in a 185 ks observation with the Chandra X-ray Observatory and as a high-redshif…
Scaling relations of supersonic turbulence in star-forming molecular clouds
Stanislav Boldyrev, Aake Nordlund, Paolo Padoan
We present a direct numerical and analytical study of driven supersonic MHD turbulence that is believed to govern the dynamics of star-forming molecular clouds. We describe statist…
Capabilities of the NASA/IPAC Extragalactic Database (NED) in the Era of a Global Virtual Observatory
Joseph M. Mazzarella, Barry F. Madore, George Helou +1
We review the capabilities of the NASA/IPAC Extragalactic Database (NED, http://ned.ipac.caltech.edu) for information retrieval and knowledge discovery in the context of a globally…
PLANCK: systematic effects induced by periodic fluctuations of arbitrary shape
Aniello Mennella, Marco Bersanelli, Carlo Burigana +4
A fundamental requirement in the new generation of high resolution Cosmic Microwave Background imaging experiments is a strict control of systematic errors that must be kept at mic…
An X-ray Selected Galaxy Cluster at z=1.11 in the Rosat Deep Cluster Survey
S. A. Stanford, B. P. Holden, P. Rosati +4
We report the discovery of an X-ray luminous galaxy cluster at z =1.11. RDCS J0910+5422 was selected as an X-ray cluster candidate in the ROSAT Deep Cluster Survey on the basis of…
Tomographic Separation of Composite Spectra. VIII. The Physical Properties of the Massive Compact Binary in the Triple Star System HD 36486 (delta Orionis A)
James A. Harvin, Douglas R. Gies, William G. Bagnuolo +2
Double-lined spectroscopic orbital elements have recently been found for the central binary in the massive triple, delta Orionis A based on radial velocities from cross-correlation…
Interferometric Mapping of Magnetic Fields in Star-forming Regions II. NGC2024 FIR5
Shih-Ping Lai, Richard M. Crutcher, Jose M. Girart +1
We present the first interferometric polarization maps of the NGC2024 FIR5 molecular core obtained with the BIMA array at approximately 2 arcsec resolution. We measure an average p…
The Anomalous Trajectories of the Pioneer Spacecraft
Michael Martin Nieto, John D. Anderson, Philip A. Laing +2
Because of their unique designs, the Pioneer 10 and 11 spacecraft have provided the cleanest Doppler, deep-space navigation data. Analysis of this data can be interpreted as showin…
Cloning a Qutrit
Nicolas J. Cerf, Thomas Durt, Nicolas Gisin
We investigate several classes of state-dependent quantum cloners for three-level systems. These cloners optimally duplicate some of the four maximally-conjugate bases with an equa…
Fundamental Radar Properties: Hidden Variables in Spacetime
Andrew K. Gabriel
A derivation of the properties of pulsed radiative imaging systems is presented with examples drawn from conventional, synthetic aperture, and interferometric radar. A geometric co…
