Hot white dwarfs and pre-white dwarfs discovered with SALT
(Oxford University Press, 2023)
The Southern African Large Telescope survey of helium-rich hot subdwarfs aims to explore evolutionary pathways among groups of highly evolved stars. The selection criteria mean that several hot white dwarfs and related ...
Intrinsic scatter of caustic masses and hydrostatic bias: An observational study
(EDP Sciences, 2017)
All estimates of cluster mass have some intrinsic scatter and perhaps some bias with true mass even in the absence of measurement
errors for example caused by cluster triaxiality and large scale structure. Knowledge of ...
The fore ground transfer function for H I intensity mapping signal reconstruction: MeerKLASS and precision cosmology applications
(Oxford University Press, 2023)
Blind cleaning methods are currently the preferred strategy for handling foreground contamination in single-dish H I intensity mapping surv e ys. Despite the increasing sophistication of blind techniques, some signal loss ...
