The VIRGO project is a physics experiment; its aim is the detection of gravitational waves. ... It has not yet been possible to detect directly the gravitational waves: it remains one of the major challenges of experimental physics. ... Interferometric antennas for gravitational waves Gravitational waves distort space-time: along two perpendicular directions, the distances between fixed points will increase (resp. decrease), at the arrival of a gravitational wave. ...

Cosmic Microwave Background Statistics for a Direction-Dependent Primordial Power Spectrum by A. R. Pullen and M. Kamionkowski . The authors developed cosmic microwave background statistics for a primordial power spectrum, motivated from the needs of testing the cosmological common assumption, i.e. the statistical isotropy of primordial perturbations. ...
. These are all basically the same things: waves of entwined electricity and magnetism flying through space: the only thing that’s different is the wavelength. You also get waves longer than radio and shorter than Gamma Rays - but these are very rare, and as far as we know useless (at present). Our eyes are only sensitive to visible light. Previous slide .

... Before the modern era of technological astronomy, to know anything about the Universe beyond our planet we relied on light. ... Historically the two rival ideas were that light was either a stream of tiny bullet-like particles or a wave wobbling its way through space. ... The light we see (visible light which is not the tautology it sounds) is only part of the electromagnetic spectrum, a great sweep of radiations which also includes radio, infra-red, ultra-violet, x-rays and gamma rays. ...
... ASpect is spectrum analysis package being developed at ST ScI. We discuss the implementation of a GUI using the IRAF Object Manager, the ASpect task design, and the mechanics of performing a fit to a spectral feature with ASpect. ASpect is a spectrum and line analysis package being developed at ST ScI. ... For example, the fit library ``knows'' about the component and spectrum objects but a given spectrum or component object knows nothing of fitting. ...

... The spectrum of the brightest star, our Sun, shows several dark gaps perpendicular to the flow of it’s colours (figure 1). These so called spectral absorption lines where discovered in 1802 by the English scientist William Wollaston. ...
