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 ... -
Sub-millimetre observations of periodic methanol maser sources
(North-West University, 2019)One of the properties of high-mass star forming regions is that they are associated with masers. A small group of these star forming regions contain periodic methanol masers. A significant aspect of the periodic methanol ... -
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 ...
