Sentences with phrase «results on cosmic rays»

Not exact matches

The study notes that narrowing down that percent range requires particle accelerator experiments on water ice to more accurately gauge the number of chemical reactions that result per unit of energy deposited by cosmic rays and solar energetic particles.

The resulting interaction converted magnetic energy into kinetic energy and sent charged particles such as cosmic rays raining down on Earth's magnetosphere, the region around Earth where its own magnetic field is stronger than other magnetic fields in space.

Using 1600 detectors spread over 3000 square kilometres, Auger should be able to determine the energies of incoming cosmic rays and shed more light on the Akeno results.

Note that the last remark can go either way, as the solar signal can even be more enhanced at the cost of the sensitivity for the greenhouse signal... And from Hansen ea.: «Solar irradiance change has a strong spectral dependence [Lean, 2000], and resulting climate changes may include indirect effects of induced ozone change [RFCR; Haigh, 1999; Shindell et al., 1999a] and conceivably even cosmic ray effects on clouds [Dickinson, 1975].

Results from the Alpha Magnetic Spectrometer (AMS) on the International Space Station (ISS) will be the focus of the three day «AMS Days at CERN» meeting, an occasion that brings together many of the world's leading theoretical physicists and principal investigators of some of the major experiments exploring the field of cosmic ray physics (IceCube, Pierre Auger Observatory, Fermi - LAT, H.E.S.S. and CTA, the Telescope Array, JEM - EUSO, and ISS - CREAM).

Regarding the CERN / CLOUD results suggesting an aerosol nucleation link with cosmic - rays, I was wondering why the focus is always on clouds?

Critics of this result might argue that the solar forcing in these experiments is only based on the estimated change in total irradiance, which might be an underestimate, or that does not include potential indirect amplifying effects (via an ozone response to UV changes, or galactic cosmic rays affecting clouds).

Svensmark (1998) later proposed that changes in the inter-planetary magnetic fields (IMF) resulting from variations on the sun can affect the climate through galactic cosmic rays (GCR) by modulating earth's cloud cover.

I have to say that this is mostly over my head, but I note that a recent Scientific American article on how cosmic rays might be the seeds for a cascade which results in lightning, and that without these rays, lightning might not happen was pretty cool.

Renown solar scientist Dr. K.G. McCracken from the Institute for Physical Science and Technology, University of Maryland, in 2007 published paper: Changes in the cosmic ray and heliomagnetic components of space climate, 1428 — 2005, including the variable occurrence of solar energetic particle events McCracken 2007 paper Major result of McCracken investigation based on 10Be dating is: the estimated annual average heliospheric magnetic field strength near Earth, 1428 — 2005, based on the inter-calibrated cosmic ray record as shown in Fig. 2 on p. 1073 (4 of 8).

The results obtained provide evidence that the mechanism of solar activity and cosmic ray influences on the lower atmosphere circulation involves changes in the evolution of the stratospheric polar vortex.

The CLOUD project at the European Center for Nuclear Research is probing the Svensmark - Shaviv hypothesis on the role of cosmic rays modulated by the solar magnetic field on the low cloud coverage; the first and encouraging results have been published in Nature.

Solar cycles of magnetic variability result in changes in the luminal spectra of the sun, the properties of the solar wind, and the flux of galactic cosmic rays incident on Earth's atmosphere.

The Dark Matter Particle Explorer (DAMPE, also known as Wukong) mission published its first scientific results on Nov. 30 in Nature, presenting the precise measurement of cosmic ray electron flux, especially a spectral break...
