21-cm power spectrum and ionization bias as a probe of long-mode modulated non Gaussian sky

15 Aug 2019 Khosravi Shahram Ghazizadeh Amirabbas Baghram Shant

The observed hemispherical power asymmetry in cosmic microwave background radiation can be explained by long wavelength mode (long-mode) modulation. In this work we study the prospect of the detection of this effect in the angular power spectrum of 21-cm brightness temperature... (read more)
