Light cone anisotropy in 21 cm signal from the epoch of reionization
Karolina Zawada, Benoit Semelin, Patrick Vonlanthen +2
Using a suite of detailed numerical simulations we estimate the level of anisotropy generated by the time evolution along the light cone of the 21cm signal from the epoch of reioni…

Canonical gauge-invariant variables for scalar perturbations in synchronous coordinates
Zdzislaw A. Golda, Andrzej Woszczyna, Karolina Zawada
Under an appropriate change of the perturbation variable Lifshitz-Khalatnikov propagation equations for the scalar perturbation reduce to d'Alembert equation. The change of variabl…
