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. Journal Article is sometimes called a Scientific Article, a Peer-Reviewed Article, or a Scholarly Research Article. Together, journal articles in a particular field are often referred to as The Literature. Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method. Because articles in scientific journals are specific, meticulously cited and peer-reviewed, journal databases are the best place to look for information on previous research on your species. Without a background in the field, journal articles may be hard to understand - however, you do not need to understand an entire article to be able to get valuable information from it.
