Search for radio recombination lines towards the gravitational lens PKS 1830-211
Niruj R. Mohan, K. R. Anantharamaiah, W. M. Goss
A search for radio recombination lines near 20 cm at z=0.193 and z=0.886 towards the gravitational lens system PKS 1830-211 has yielded upper limits on the line optical depth of 5…

Radio recombination lines from starburst galaxies : high and low density ionized gas
Niruj R. Mohan, K. R. Anantharamaiah, W. M. Goss
Radio recombination lines (RRL) at 8 GHz and 15 GHz detected from four starburst galaxies are shown to arise in compact high density HII regions, which are undetectable below ~4 GH…
