Constraints on distances to Galactic Centre non-thermal filaments from HI absorption
2003
Astronomical Notes - Astronomische Nachrichten
We have studied HI absorption towards three non-thermal filaments (NTFs) Sgr C, G359.54+0.18 and G359.79+0.17 using the Giant Metrewave Radio Telescope (GMRT). Our study, for the first time, constrains the distance of the Sgr C NTF and the HII region seen associated with the NTF in the sky plane, to within a few hundred parsecs from the Galactic Centre (GC). A molecular cloud with a velocity of −100 km s −1 appears to be associated with the central part of the Sgr C NTF. Our study also
