Highly-detailed radio-telescope images have pinpointed the locations where a stellar explosion called a nova emitted gamma rays, the most energetic form of electromagnetic waves. The discovery reveale...
A Hotspot for Powerful Cosmic Rays PHYSICISTS A STEP CLOSER TO FINDING MYSTERIOUS SOURCES
The universe Ray Hot spots. Mysterious The big dipper. High-energy cosmic rays The sun
2014/7/18
July 8, 2014 – An observatory run by the University of Utah found a “hotspot” beneath the Big Dipper emitting a disproportionate number of the highest-energy cosmic rays. The discovery moves physics a...
The New Generation Atlas of Quasar Spectral Energy Distributions from Radio to X-rays
Generation Atlas Spectral Energy Distributions Radio
2011/9/30
We have produced the next generation of quasar spectral energy distributions (SEDs), essentially updating the work of Elvis et al. (1994) by using high-quality data obtained with several space and gro...
Multi-parametric Effect of Solar Activity on Cosmic Rays
Sun solar parameters cosmic ray modulation running multiple correlation method
2010/9/16
The long-term modulation of cosmic ray intensity (CRI) by different solar activity (SA) parameters and an inverse correlation between individual SA parameter and CRI is well known. Earlier, it has bee...
One way to assess a drug’s effectiveness is to image the changes that it produces in the tissue of patients. But this is very challenging in the case of Alzheimer’s disease, because conventional tools...
