Cosmic Ray Astrophysics
The problem of the origin of cosmic rays is considered in an astronomical context and the current observational situation summarised. The evidence for acceleration in supernova remnants is critically examined.
متن کاملCosmic Ray Astrophysics with AMS-02
The Alpha Magnetic Spectrometer (AMS) is a cosmic ray (CR) experiment that will operate on the International Space Station for three years, measuring the particle spectra in the rigidity range from 0.2 GV to 2 TV. The AMS-02 detector will provide measurements with unprecedented statistics of the hadronic and leptonic cosmic rays, allowing for a better study of the Earth magnetosphere through th...
متن کاملAstrophysics 32 7 Lecture 7 : Cosmic Distances
GR states that the laws of physics are the same in any coordinates. However, some coordinates are easier to work with then others. One such set of coordinates are comoving coordinates in which an observer is comoving with the Hubble flow. Only for these observers in the comoving coordinates, the Universe is isotropic (otherwise, portions of the Universe will exhibit a systematic bias: portions ...
متن کاملLow Energy Cosmic Ray Interactions in Astrophysics
Gamma ray emission lines resulting from accelerated particle bombardment of ambient gas can serve as an important spectroscopic tool for abundance determinations. The method is illustrated by considering the gamma ray line emission observed from solar flares. The observation of similar gamma ray lines from Orion suggests the existence of large fluxes of low energy Galactic cosmic rays. The role...
متن کاملPossible Cosmic Quantum Mechanics in Astrophysics
Recent observations confirm that galactic redshifts are quantized and hint at a possible new form of quantum mechanics on a cosmic scale, which could probably explain these observed properties of galaxies. This brief paper investigates a possible relationship between the new cosmic Planck constant and other fundamental constants of physics. g
