Power Spectrum Analysis of Physikalisch-Technische Bundesanstalt Decay-Rate Data: Evidence for Solar Rotational Modulation
Solar and Stellar Astrophysics (astro-ph.SR) Nuclear Experiment (nucl-ex) Instrumentation and Detectors (physics.ins-det)
2010/12/29
Evidence for an anomalous annual periodicity in certain nuclear decay data has led to speculation concerning a possible solar influence on nuclear processes.
Deconvolution of window effect in galaxy power spectrum analysis
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
We develop a new method for deconvolving the smearing effect of the survey window in the analysis of the galaxy multipole power spectra from a redshift survey. This method is based on the deconvolutio...
Power Spectrum Analysis of Mount-Wilson Solar Diameter Measurements: Evidence for Solar Internal R-mode Oscillations
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
This article presents a power-spectrum analysis of 39,024 measurements of the solar diameter made at the Mount Wilson Observatory from 1968.670 to 1997.965. This power spectrum contains a number of ve...
