Lynx X-Ray Observatory
AstroAI is a center that develop artificial intelligence to solve some of the most interesting and challenging problems in astronomy.
In extreme environments, where pressure, temperature, and density are high, atoms change the way they emit and absorb light. Electrons are stripped from nuclei, forming a plasma, and the ions emit X-rays when struck by free electrons. To assist astronomers in identifying atoms under these harsh conditions, the Center for Astrophysics | Harvard & Smithsonian maintains the AtomDB database of X-ray spectra. This catalog provides essential information for studying conditions in many astrophysical environments, including those near black holes, stars, and neutron stars.
PINTofALE (Package for Interactive Analysis of Line Emission)
Astrophysical environments are often strikingly different from those on Earth, but there’s no direct way for astronomers to measure conditions in space. Instead, they must infer environmental properties from the behavior of atoms, particularly the way they absorb and emit light. For this to work, researchers need to use databases of atomic spectra, which requires writing or using computer code. PINTofALE (Package for Interactive Analysis of Line Emission) is a software toolkit designed to streamline this process, giving astronomers a powerful way to use X-ray and ultraviolet atomic data without having to write their own code every time. The package was developed by researchers at the Center for Astrophysics | Harvard & Smithsonian, and is provided for free as a service to astronomers.
