Physics and Astrophysics

The American Astronomical Society (AAS) is the major organization of professional astronomers in North America. The mission of the American Astronomical Society is to enhance and share humanity's scientific understanding of the Universe.

The American Physical Society is a non-profit membership organization working to advance and diffuse the knowledge of physics through its outstanding research journals, scientific meetings, and education, outreach, advocacy and international activities. APS represents over 50,000 members, including physicists in academia, national laboratories and industry in the United States and throughout the world

The American Institute of Physics is a not-for-profit corporation chartered in 1931 to provide publishing and distribution services for scientific and technical societies. AIP is the publisher or co-publisher of 11 journals, many with the highest citation ratings in their category, as well as Physics Today and the AIP Conference Proceedings Series. AIP's online publishing platform, Scitation, currently hosts more than 1,000,000 articles from more than 150 scholarly publications in fields including physics, chemistry, geology, engineering, acoustics, and other sciences.

IOP Publishing, a not for profit company wholly owned by the Institute of Physics, is one of the largest and most dynamic publishers of physics information in the world. Our publishing activity, which dates back to 1874, includes a wide range of journals, magazines and community websites.

Since 1916, OSA has worked to advance the common interests of the field, providing educational resources to the scientists, engineers and business leaders who work in the field by promoting the science of light and the advanced technologies made possible by optics and photonics. The organization's members span many disciplines, including physics, biology, medical research, electrical engineering, display component engineering, communications, vision, astronomy, meteorology, materials science, imaging and others.

The American Nuclear Society is a not-for-profit, international, scientific and educational organization. It was established by a group of individuals who recognized the need to unify the professional activities within the diverse fields of nuclear science and technology
