interferometer detectors Yiqiu Ma, David G Blair, ∗ Chunnong Zhao, and William Kells 1: School of Physics, University of Western Australia 2: California Institute of Technology Abstract In this paper, we discuss the energy interaction between gravitational waves and the laser interferometer gravitational wave detectors. We show that the widely held view that the laser interferometer gravitation...

We have investigated the dependence of the wavelength shift of the coronal emission line profiles on the line of sight velocity of the emitting plasma. The results of our numerical calculations point out that, while the wavelength shift of the collisionally excited component of the line is related to the line of sight velocity by the usual formula for the Doppler effect, that of the resonantly ...

We analyze basic properties of about 200 metal systems observed in high resolution spectra of 9 quasars by Boksenberg, Sargent& Rauch (2003). The measured Doppler parameters for the hydrogen and carbon lines are found to be different by a factor

The helicity-rotation coupling and its current empirical basis are examined. The modification of the Doppler effect due to the coupling of photon spin with the rotation of the observer is considered in detail in connection with its applications in the Doppler tracking of spacecraft. Further implications of this coupling and the possibility of searching for it in the intensity response of a rota...

We present Very Long Baseline Array (VLBA) observations of the radio source J1625+4134 at 22 and 15 GHz and analyze them in concurrence with other existing VLBI data on this source. The high resolution images at 15 and 22 GHz show a short and bending jet which has about 270 • difference in position angle with the northern jet detected at lower frequencies. The new high resolution data, combined...

2014 The shape of Hanle (zero field level crossing) signals may be strongly distorted if the spectral profile of the exciting light varies rapidly on the scale of the natural linewidth, provided that the Doppler width in the scattering region is not very large compared with the natural width. A Hanle experiment has been performed at the resonance line of calcium. The exciting light had a spectr...

Non-coherent signal with unknown delay and Doppler is recovered by Gabor Division/Spread Spectrum System (GD/S). A transmitted signal in GD/S is expressed by a Gabor expansion whose expansion coefficient is a product of time domain (TD) and frequency domain (FD) spread spectrum (SS) codes. A receiver in GD/S employs multiple TD integrators with TD SS codes and a prescribed delay and FD integrat...

A positive surge results from a sudden change in flow that increases the depth. It is the unsteady flow analogy of the stationary hydraulic jump and a geophysical application is the tidal bore. Positive surges are commonly studied using the method of characteristics and the Saint-Venant equations. The article presents the results from new experimental investigations conducted in a large rectang...

This paper deals with the Autler–Townes doublet structure. Applied driving and probing laser fields can have arbitrary intensities. An explanation is given of the broadening of doublet components with the growth of probing field intensity, which was observed in experiment. The effects of Doppler averaging are discussed.

Comparisons are made between horizontal wind measurements carried out using a VHF-radar system at Aberystwyth (52.4°N, 4.1°W) and radiosondes launched from Aberporth, some 50 km to the southwest. The radar wind results are derived from Doppler wind measurements at zenith angles of 6° in two orthogonal planes and in the vertical direction. Measurements on a total of 398 days over a 2-year period...
