Ionized plasmas are ubiquitous in the Universe: from stellar coronae to cosmic web filaments. Characterizing ionized plasmas is critical to address many astrophysical questions, for instance, the interplay among stars, supermassive black holes, and their host galaxies. High-resolution spectra exhibit a wealth of characteristic emission and absorption features. Plasma diagnostics can constrain the physical properties (e.g., temperature, density, abundance, and kinematics) of the ionized plasmas found in a wide range of astrophysical environments. Continuous development of plasma codes and the atomic database is essential to fully exploit the capability of future observatories with high-resolution spectroscopy.

Dr. Junjie Mao is currently a Research Associate at the University of Strathclyde in the UK. He obtained his Ph.D. at the Leiden University and SRON Netherlands Institute for Space Research in 2018. His research interest revolves around high-resolution spectroscopy of astrophysical plasmas, including ionized winds driven away from supermassive black holes, elemental abundances of the hot atmospheres of individual galaxies and galaxy assemblies, development of plasma models, and theoretical calculations of atomic data.
