Detectability of the 21 cm-CMB cross-correlation from the EoR
Hiroyuki Tashiro, Nabila Aghanim, Mathieu Langer +3
The 21-cm line fluctuations and the cosmic microwave background (CMB) are powerful probes of the epoch of reionisation of the universe. We study the potential of the cross-correlat…
Cross-correlation Study between the Cosmological 21-cm Signal and the kinetic Sunyaev-Zel'dovich effect
Vibor Jelic, Saleem Zaroubi, Nabila Aghanim +6
The Universe's Epoch of Reionization (EoR) can be studied using a number of observational probes that provide complementary or corroborating information. Each of these probes suffe…
Foregrounds for observations of the cosmological 21 cm line: I. First Westerbork measurements of Galactic emission at 150 MHz in a low latitude field
G. Bernardi, A. G. de Bruyn, M. A. Brentjens +11
We present the first results from a series of observations conducted with the Westerbork telescope in the 140--160 MHz range with a 2 arcmin resolution aimed at characterizing the…
Non-parametric foreground subtraction for 21cm epoch of reionization experiments
Geraint Harker, Saleem Zaroubi, Gianni Bernardi +12
An obstacle to the detection of redshifted 21cm emission from the epoch of reionization (EoR) is the presence of foregrounds which exceed the cosmological signal in intensity by or…
