The Radiation Transfer at a Layer of Magnetized Plasma With Random Irregularities [PDF]
, 1998 The problem of radio wave reflection from an optically thick plane monotonous layer of magnetized plasma is considered at present work. The plasma electron density irregularities are described by spatial spectrum of an arbitrary form.

Multi-density model of the ionised gas in NGC 253 using radio recombination lines [PDF]
, 2004 We have imaged the H92alpha (8.3 GHz), H75alpha (15 GHz), and H166alpha (1.4 GHz) Radio Recombination Lines (RRLs) from NGC 253 at resolutions of 4.5 pc (0.4"), 2.5 pc (0.2") and 53 pc (4.5") respectively. The H92alpha line arises from individual compact
