Cross-correlating 21cm intensity maps with Lyman Break Galaxies in the post-reionization era by Villaescusa-Navarro, F, Viel, M, Alonso, D, Datta, K, Bull, P, Santos, M

“…Using a high resolution N-body simulation, populated with neutral hydrogen a posteriori, we forecast for the expected LBG-21cm cross-spectrum and its error for a 21cm field observed by the Square Kilometre Array (SKA1-LOW and SKA1-MID), combined with a spectroscopic LBG survey with the same volume. …”

The prevalence of core emission in faint radio galaxies in the SKA Simulated Skies by Whittam, I, Jarvis, M, Green, D, Heywood, I, Riley, J

“…We suggest that this is because the faint radio galaxies are not modelled correctly in the simulations and show that by adding a flat-spectrum core component to the Fanaroff and Riley type-I (FRI) sources in the Square Kilometre Array (SKA) Simulated Skies, the observed 15 GHz source counts can be reproduced. …”

Atomic and molecular absorption in redshifted radio sources by Curran, SJ, Whiting, MT, Allison, JR, Tanna, A, Sadler, EM, Athreya, R
