Optical Constants of Silicon Carbide for Astrophysical Applications. II. Extending Optical Functions from Infrared to Ultraviolet Using Single-Crystal Absorption Spectra
(American Astronomical Society, 2009)
Laboratory measurements of unpolarized and polarized absorption spectra of various samples and crystal structures of silicon carbide (SiC) are presented from 1200-35000 cm−1 (λ ∼ 8-0.28 μm) and used to improve the
accuracy ...
Beyond the standard IAU framework
(Cambridge university Press, 2010)
We discuss three conceivable scenarios of extension and/or modification of the IAU relativistic resolutions on time scales and spatial coordinates beyond the Standard IAU Framework. These scenarios include: (1) the formalism ...
Millimeter Laser Ranging to the Moon: a comprehensive theoretical model for advanced data analysis
(arXiv, 2009)
Lunar Laser Ranging (LLR) measurements are crucial for advanced exploration of the evolutionary history of the lunar orbit, the laws of fundamental gravitational physics, selenophysics and geophysics as well as for future ...
The X-Ray Luminosity Function of Nearby Rich and Poor Clusters of Galaxies:A Cosmological Probe
(American Astronomical Society, 1999)
In this Letter, we present a new determination of the local (z · 0.09) X-ray luminosity function (XLF) using a large, statistical sample of 294 Abell clusters and the ROSAT All-Sky Survey. Despite the optical selection of ...
Annealing-Dependent Magnetic Depth Profile in Ga[1-x]Mn[x]As
(American Physical Society, 2004)
We have studied the depth-dependent magnetic and structural properties of as-grown and optimally annealed Ga[1-x]Mn[x]As films using polarized neutron reflectometry. In addition to increasing total magnetization, the ...
Post-Newtonian Reference Frames for Advanced Theory of the Lunar Motion and a New Generation of Lunar Laser Ranging
(arXiv, 2009)
We construct a set of post-Newtonian reference frames for a comprehensive study of the orbital dynamics and rotational motion of Moon and Earth by means of lunar laser ranging (LLR) with the precision of one millimeter. ...
Astrodynamical Space Test of Relativity using Optical Devices I (ASTROD I) - A class-M fundamental physics mission proposal for Cosmic Vision 2015-2025
(arXiv, 2008)
ASTROD I is a planned interplanetary space mission with multiple goals. The primary aims are: to test General Relativity with an improvement in sensitivity of over 3 orders of magnitude, improving our understanding of ...
Post-Newtonian limitations on measurement of the PPN parameters caused by motion of gravitating bodies
(Wiley, 2009)
We derive an explicit Lorentz-invariant solution of the Einstein and null geodesic equations for data processing of the time delay and ranging experiments in the gravitational field of moving gravitating bodies of the Solar ...
Tuning intermolecular interactions in di-octyl substituted polyfluorene via hydrostatic pressure
(arXiv, 2009)
Polyfluorenes (PFs) represent a unique class of poly para-phenylene based blue-emitting polymers with intriguing structure-property relationships. Slight variations in the choice of functionalizing side chains result in ...
Progress in Measurements of the Gravitational Bending of Radio Waves Using the VLBA
(American Astronomical Society, 2009)
We have used the Very Long Baseline Array (VLBA) at 43, 23, and 15 GHz to measure the solar gravitational deflection of radio waves among four radio sources during an 18 day period in 2005 October. Using phase- referenced ...
Reference frames, gauge transformations and gravitomagnetism in the post-Newtonian theory of the lunar motion
(Proceedings of the International Astronomical Union, 2010)
We construct a set of reference frames for description of the orbital and rotational motion of the Moon. We use a scalar-tensor theory of gravity depending on two parameters of the parametrized post- Newtonian (PPN) formalism ...
Units of relativistic time scales and associated quantities
(arXiv, 2010)
This note suggests nomenclature for dealing with the units of various astronomical quantities that are used with the relativistic time scales TT, TDB, TCB and TCG. It is suggested to avoid wordings like "TDB units" and "TT ...
Recent VLBA/VERA/IVS Tests of General Relativity
(arXiv, 2009)
We report on recent VLBA/VERA/IVS observational tests of General Relativity. First, we will summarize the results from the 2005 VLBA experiment that determined gamma with an accuracy of 0.0003 by measuring the deflection ...
On the two approaches to the data analysis of the Cassini interplanetary relativity experiment
(Elsevier, 2009)
We compare two theoretical approaches to the data analysis of the Cassini relativity experiment based on the Doppler tracking and the time delay technique that were published correspondingly by Kopeikin et al. [S.M. Kopeikin, ...
Radio Interferometric Tests of General Relativity
(arXiv, 2009)
Since VLBI techniques give microarcsecond position accuracy of celestial objects, tests of GR using radio sources as probes of a gravitational field have been made. We present the results from two recent tests using the ...
Stability of pulsar rotational and orbital periods
(arXiv, 2009)
Millisecond and binary pulsars are the most stable astronomical standards of frequency. They can be applied to solving a number of problems in astronomy and time-keeping metrology including the search for a stochastic ...
