An investigation into maser variability in high-mass star forming regions
(North-West University, 2018)The two brightest class II methanol masers - at 6.7- and 12.2-GHz, are exclusively associated with the early phases of high-mass star formation. This implies that studying these maser species is an indirect probe of the ... -
An investigation into the variability of methanol and hydroxyl masers in the star-forming region G12.89+0.49
(North-West University, 2006)It is now widely accepted that 6.7 GHz and 12.2 GHz class I1 methanol masers are signposts of very young high mass star-forming regions. The exact location of these masers is still a matter of debate, they may be in disks ... -
A search for radio recombination lines in selected ultra-compact HII regions
(North-West University (South Africa), 2020)The role that high-mass stars play in galaxies is significant. They strongly affect their environment through their strong ultraviolet radiation, powerful winds, and supernova explosions. The physical processes that control ... -
Variability of methanol and OH masers associated with the star forming region G339.62-0.12
(North-West University (South Africa), 2020)Astrophysical maser emission from various molecules and in a number of astrophysical environments is now a well-known phenomenon. Since the first discovery of hydroxyl (OH) maser emission by Weinreb et al. (1963), the use ...
