The 21-cm signature of X-ray heated halos around galaxies during cosmic dawn
Ka-Hou Leong, Avery Meiksin
X-rays emitted by high mass X-ray binaries (HMXBs) and supernovae-driven winds in the first galaxies during Cosmic Dawn are expected to warm the intergalactic medium prior to its r…

A comparison of numerical methods for computing the reionization of intergalacitc hydrogen and helium by a central radiating source
Ka-Hou Leong, Avery Meiksin, Althea Lai +1
We compare numerical methods for solving the radiative transfer equation in the context of the photoionization of intergalactic gaseous hydrogen and helium by a central radiating s…

Testing extreme-axion wave dark matter using the BOSS Lyman-Alpha forest data
Ka-Hou Leong, Hsi-Yu Schive, Ui-Han Zhang +1
Using cosmological particle hydrodynamical simulations and uniform ultraviolet backgrounds, we compare Lyman- forest flux spectra predicted by the conventional cold dark matter…
