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...
Characterisation of the non-Gaussianity of radio and IR point-sources at CMB frequencies
ology: Cosmic Microwave Background, large scale structures Galaxiesstatistics, Infrared: galaxies Radio continuum: galaxies Methods: statistical
2011/10/8
The present study focuses on the characterisation of the non-Gaussianity produced by radio point-sources and, for the first time, by infrared sources in the frequency range of the CMB from 30 to 350 G...
