Dielectronic recombination and stability of warm gas in AGN

Susmita Chakravorty (Astronomy Department, Harvard University, Cambridge, MA, USA) High resolution ultraviolet and X-ray spectra show that material outflow occur from the close neighbourhoods of super-massive black holes in active galactic nuclei (AGN). It is important to understand the structure and … Continue reading

Effects of CI for DR of Na-like ions forming Mg-like ions

Kwon, D. H. (Korea Atomic Energy Research Institute) and Savin, D.W. (Columbia University) Theoretical dielectronic recombination (DR) rate coefficient calculations can be sensitive to configuration interaction (CI) between resonances with different captured electron principle quantum numbers n. Here we explore the … Continue reading
