Hydrogen-like nitrogen radio line from hot interstellar and warm-hot intergalactic gas
R. A. Sunyaev, D. Docenko
Hyperfine structure lines of highly-charged ions may open a new window in observations of hot rarefied astrophysical plasmas. In this paper we discuss spectral lines of isotopes an…

Optical and near-infrared recombination lines of oxygen ions from Cassiopeia A knots
D. Docenko, R. A. Sunyaev
Context. Fast-moving knots (FMK) in the Galactic supernova remnant Cassiopeia A consist mainly of metals and allow to study element production in supernovae and shock physics in gr…

Fine-structure infrared lines from the Cassiopeia A knots
D. Docenko, R. A. Sunyaev
Aims: Archival observations of infrared fine-structure lines of the young Galactic supernova remnant Cassiopeia A allow us to test existing models and determine the physical parame…
