Astroparticle physics is a branch of science that studies elementary particles of astronomical origin and its relation with cosmology and astrophysics. It is a new field with upcoming research in astronomy, detector physics, cosmology, astrophysics and particle physics. Astroparticle physics has led to the development of new detection methods to observe cosmic particles including gamma rays, neutrinos and cosmic rays at the highest energy.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
