Williams et al. Reply (to the Comment by Dumin on "Progress in Lunar Laser Ranging Tests of Relativistic Gravity")
James G. Williams, Slava G. Turyshev, Dale H. Boggs
A decreasing gravitational constant, G, coupled with angular momentum conservation is expected to increrase a planetary semimajor axis, a, as \dot a/a=-\dot G/G. Analysis of lunar…
Spitzer Observations of 3C Quasars and Radio Galaxies: Mid-Infrared Properties of Powerful Radio Sources
K. Cleary, C. R. Lawrence, J. A. Marshall +2
We have measured mid-infrared radiation from an orientation-unbiased sample of 3CRR galaxies and quasars at redshifts 0.4 < z < 1.2 with the IRS and MIPS instruments on the Spitzer…
IR Background Anisotropies in Spitzer GOODS images and constraints on first galaxies
Asantha Cooray, Ian Sullivan, Ranga-Ram Chary +6
We describe the angular power spectrum of unresolved 3.6 micron IR light in Spitzer GOODS fields. The amplitude of the anisotropy spectrum decreases with decreasing flux threshold…
New Hubble Space Telescope Discoveries of Type Ia Supernovae at z > 1: Narrowing Constraints on the Early Behavior of Dark Energy
Adam G. Riess, Louis-Gregory Strolger, Stefano Casertano +18
We have discovered 21 new Type Ia supernovae (SNe Ia) with the Hubble Space Telescope (HST) and have used them to trace the history of cosmic expansion over the last 10 billion yea…
Turbulent Mixing and the Dead Zone in Protostellar Disks
N. J. Turner, T. Sano, N. Dziourkevitch
We investigate the conditions for the presence of a magnetically inactive dead zone in protostellar disks, using 3-D shearing-box MHD calculations including vertical stratification…
The 15 - 20 Micron Spitzer Spectra of Interstellar Emission Features in NGC 7023
K. Sellgren, K. I. Uchida, M. W. Werner
We present 15 - 20 micron long-slit spectra, from the Infrared Spectrograph (IRS) on Spitzer, of NGC 7023. We observe recently-discovered interstellar emission features, at 15.9, 1…
Rotation and Color Properties of the Nucleus of Comet 2P/Encke
S. C. Lowry, P. R. Weissman
We present results from CCD observations of comet 2P/Encke acquired at Steward Observatory's 2.3m Bok Telescope on Kitt Peak obtained in Oct. 2002, when the comet was near aphelion…
First Terrestrial Soft X-ray Auroral Observation by The Chandra X-ray Observatory
Anil Bhardwaj, G. Randall Gladstone, Ronald F. Elsner +6
Northern auroral regions of Earth were imaged with energetic photons in the 0.1-10 keV range using the High-Resolution Camera (HRC-I) aboard the Chandra X-ray Observatory at 10 epo…
Benzene formation in the inner regions of protostellar disks
Paul M. Woods, Karen Willacy
Benzene (c-C6H6) formation in the inner 3 AU of a protostellar disk can be efficient, resulting in high abundances of benzene in the midplane region. The formation mechanism is dif…
Infrared Counterparts to Chandra X-Ray Sources in the Antennae
D. M. Clark, S. S. Eikenberry, B. R. Brandl +7
We use deep J and Ks images of the Antennae (NGC 4038/9) obtained with WIRC on the Palomar 200-inch telescope, together with the Chandra X-ray source list of Zezas et al. (2002a),…
Using LISA EMRI sources to test off-Kerr deviations in the geometry of massive black holes
Leor Barack, Curt Cutler
Inspirals of stellar-mass compact objects into black holes are especially interesting sources of gravitational waves for LISA. We investigate whether the emit…
Interferometric Observations of RS Ophiuchi and the Origin of the Near-IR Emission
B. F. Lane, J. L. Sokoloski, R. K. Barry +7
We report observations of the recurrent nova RS Oph using long-baseline near-IR interferometry. We are able to resolve emission from the nova for several weeks after the February 2…
Exposed-key weakness of
Charlene Ahn, Kevin Birnbaum
The protocol given by Barbosa \emph{et al.}, PRL 90, 227901 (2003) claims to be a secure way of encrypting messages using mesoscopic coherent states. We show that transmission…
Spallation Residues in the Reaction 56Fe + p at 0.3, 0.5, 0.75, 1.0 and 1.5 A GeV
C. Villagrasa-Canton, A. Boudard, J. -E. Ducret +35
The spallation residues produced in the bombardment of 56}Fe at 1.5, 1.0, 0.75, 0.5 and 0.3 A GeV on a liquid-hydrogen target have been measured using the reverse kinematics techni…
Large Structures and Galaxy Evolution in COSMOS at z < 1.1
N. Scoville, H. Aussel, A. Benson +25
We present the first identification of large-scale structures (LSS) at z in the Cosmic Evolution Survey (COSMOS). The structures are identified from adaptive smoothing of g…
COSMOS : Hubble Space Telescope Observations
N. Scoville, A. Benson, A. W. Blain +50
The Cosmic Evolution Survey (COSMOS) was initiated with an extensive allocation (590 orbits in Cycles 12-13) using the Hubble Space Telescope (HST) for high resolution imaging. Her…
