Aligned metal absorbers and the ultraviolet background at the end of reionization
Doughty, Caitlin; Finlator, Kristian; Oppenheimer, Benjamin D.; Dave, Romeel; Zackrisson, Erik (Oxford University Press, 2018)We use observations of spatially-aligned C ii, C iv, Si ii, Si iv, and O i absorbers to probe the slope and intensity of the ultraviolet background (UVB) at z ∼ 6. We accom- plish this by comparing observations with ... -
Constraining the astrophysics and cosmology from 21 cm tomography using deep learning with the SKA
Hassan, Sultan; Andrianomena, Sambatra; Doughty, Caitlin (Oxford University Press, 2020)Future Square Kilometre Array (SKA) surveys are expected to generate huge data sets of 21 cm maps on cosmological scales from the Epoch of Reionization. We assess the viability of exploiting machine learning techniques, ...
