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

Probing the properties of nebular plasmas with optical and IR spectroscopy

M. J. Barlow (Dept of Physics & Astronomy, University College London) Ionized nebulae provide spectacular probes of conditions that cannot easily be recreated in the laboratory. Their spectra are dominated by dipole-forbidden transitions from ions of carbon, nitrogen, oxygen, neon … Continue reading
