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 ...
Multipole expansion for 21 cm intensity mapping power spectrum: forecasted cosmological parameters estimation for the ska observatory
(Oxford University Press, 2023)
The measurement of the large-scale distribution of neutral hydrogen in the late Universe, obtained with radio telescopes through the hydrogen 21 cm line emission, has the potential to become a key cosmological probe in the ...
