Calibrating photometric redshifts with intensity mapping observations
(American Physical Society, 2017)Imaging surveys of galaxies will have a high number density and angular resolution yet a poor redshift precision. Intensity maps of neutral hydrogen (HI) will have accurate redshift resolution yet will not resolve ... -
Gaussian process regression for foreground removal in hi intensity mapping experiments
(Oxford University Press, 2022)We apply for the first time Gaussian Process Regression (GPR) as a foreground removal technique in the context of single-dish, low redshift H I intensity mapping, and present an open-source PYTHON toolkit for doing so. We ... -
MIGHTEE: Are giant radio galaxies more common than we thought?
(Oxford University Press, 2021)We report the discovery of two new giant radio galaxies (GRGs) using the MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) survey. Both GRGs were found within a ∼}1\, deg2 region inside the COSMOS field. ... -
Radio spectral properties of star-forming galaxies in the MIGHTEE-COSMOS field and their impact on the far-infrared-radio correlation
(Oxford University Press, 2021)We study the radio spectral properties of 2094 star-forming galaxies (SFGs) by combining our early science data from theMeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) survey with VLA, GMRT ...
