The SAO/NASA Astrophysics Data System (ADS) is a digital library portal for researchers on astronomy and physics, operated for NASA by the Smithsonian Astrophysical Observatory. ADS maintains three bibliographic collections containing over 15 million records, including all arXiv e-prints. [ 1 ]
Atomic astrophysics is concerned with performing atomic physics calculations that will be useful to astronomers and using atomic data to interpret astronomical observations. Atomic physics plays a key role in astrophysics as astronomers' only information about a particular object comes through the light that it emits, and this light arises ...
For this reason, molecules and molecular ions which are unstable on Earth can be highly abundant in space, for example the H 3 + ion. Astrochemistry overlaps with astrophysics and nuclear physics in characterizing the nuclear reactions which occur in stars, as well as the structure of stellar interiors.
The Astrophysics Source Code Library (ASCL) is an online registry of scientist-written software used in astronomy or astrophysics research. The primary objective of the ASCL is to make the software used in research available for examination to improve the transparency of research.
Astrophysics Data System [28] Astrophysics, Geophysics, Physics: 13,300,000 Publications in Astronomy and Astrophysics, Physics, and the arXiv e-prints Free Harvard University: ATLA Religion Database [29] Religious studies: 3,000,000 Provides information on topics such as biblical studies, world religions, church history, and religion in social ...
During this time, scientists and software developers at the CfA also began work on what would become the Astrophysics Data System (ADS), one of the world's first online databases of research papers. [2] By 1993, the ADS was running the first routine transatlantic queries between databases, a foundational aspect of the internet today. [2]
For example, radio astronomy is most sensitive to small linear molecules with a high molecular dipole. [3] The most common molecule in the Universe, H 2 ( molecular hydrogen ), is completely invisible to radio telescopes because it has no dipole; [ 3 ] its electronic transitions are too energetic for optical telescopes, so detection of H 2 ...
