In addition to shedding light on our cosmic neighborhood, the results offer an explanation for a decades-old mystery on why we measure more incoming high-energy cosmic rays on one side of the sun than on the other.
We expect the research groups using the computer system to announce many new observational results in the future that generate new insights into hitherto unknown phenomena relating to the universe and cosmic ray particles.
At the same time, cosmic rays originating from outside the solar system spiked.
With the increase in solar activity, the primary cosmic ray intensity has decreased by 9 per cent during the past 150 years leading to lesser cloud cover and reduced albedo radiation being reflected back into space.
Besides of these phenomena of a local character, there are global reasons of cosmic ray intensity modulations determined by geophysical cyclic processes and processes related to solar activity.
For instance, at an altitude of one mile above sea level, the cosmic ray density is 3.
Scientists have discovered a previously unidentified nearby source of high-energy cosmic rays.
1) San Fernando Middle School students watch Caltech researchers install cosmic ray detectors Wednesday at their school.
Totsuka, 59, and Kajita, 42, observed neutrinos generated as cosmic rays crash into Earth's atmosphere at the institute's observatory facility Super-Kamiokande in the town of Kamioka, Gifu Prefecture.
The Keck Radar Observatory will be located in Millard County, Utah, where it will initially be co-located with Utah's Telescope Array, currently the largest "conventional" cosmic ray observatory in the Northern Hemisphere.
Study coauthor Pim Schellart, a radio astronomer at Radboud University in Nijmegen, the Netherlands, and colleagues plan to compare the timing of cosmic ray showers and lightning strikes to test that possibility.
They found a small correlation between cosmic rays and global temperatures occurring every 22 years; however, the changing cosmic ray rate lagged behind the change in temperatures by between one and two years, suggesting that the cause may not be down to cosmic rays and cloud formation, but may be due to the direct effects of the Sun.
Lu's theory has been confirmed by ongoing observations of cosmic ray, CFC, ozone and stratospheric temperature data over several 11-year solar cycles.
Scientists previously could not determine which atomic particles are responsible for emissions from the interstellar gas clouds because cosmic ray protons and electrons give rise to gamma rays with similar energies.
Fifty-two presentations are presented within sections covering the opening remarks of the workshop, cosmology, astrophysics of high-energy cosmic sources, jet sources and gamma-ray bursts, quantum gravity phenomenology, the challenge of cosmic ray production, neutrino astronomy, direction for next-generation experiments, and concluding remarks.
