We cannot observe the way the distant universe accelerates cosmic rays or produces energetic photons, but acceleration processes also occur on our Sun , though on a much more moderate scale. ... That is why such events are often missed by cosmic ray detectors near the equator, where the lowest energies are excluded by the Earth's magnetic field. The best detectors for observing solar particles are therefore those sensitive to the lowest energies of the cosmic radiation. ...

Project C - Mapping the Cosmic Web. The story of the assembly of galaxies is believed to be found in the connection between the cosmic web of gas and the known galaxies, at a variety of redshifts. The gaseous web is generally invisible except by probing the gas using distant QSOs as background sources for the study of the UV absorption lines of H I, O VI and C II, for instance. ...
