Detectability of the 21 cm-CMB cross-correlation from the EoR (2009)
Tashiro, Hiroyuki, Aghanim, Nabila, Langer, Mathieu, Douspis, Marian, Zaroubi, Saleem, Jelic, Vibor
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-correlation between 21-cm...

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 suffers from its own...
Biases on the cosmological parameters and thermal SZ residuals (2008)
Taburet, Nicolas, Aghanim, Nabila, Douspis, Marian, Langer, Mathieu
We examine the biases induced on cosmological parameters when the presence of secondary anisotropies is not taken into account in Cosmic Microwave Background analyses. We first develop an exact...
Tashiro, Hiroyuki, Silk, Joseph, Langer, Mathieu, Sugiyama, Naoshi
The S-Z effect and Faraday rotation from halos are examined over a wide mass range, an including gas condensation and magnetic field evolution. Contributions to the CMB angular power spectrum are...
Tashiro, Hiroyuki, Aghanim, Nabila, Langer, Mathieu, Douspis, Marian, Zaroubi, Saleem
The cosmic microwave background (CMB) polarisation and the 21 cm line fluctuations are powerful probes of cosmological reionisation. We study how the cross-correlation between the CMB polarisation...
Secondary B-mode polarization from Faraday rotation in clusters and galaxies (2007)
Tashiro, Hiroyuki, Aghanim, Nabila, Langer, Mathieu
We revisit the polarisation induced by Faraday rotation when Cosmic Microwave Background photons traverse magnetised plasma. We compute the secondary B-mode angular power spectrum from Faraday...
On the First Generation of Stars (2006)
We argue that the first stars may have spanned the conventional mass range rather than be identified with the Very Massive Objects (100-1000 solar masses) favoured by numerical simulations....
Small scale contributions to CMB: A coherent analysis (2006)
Douspis, Marian, Aghanim, Nabila, Langer, Mathieu
We reanalyse Cosmic Microwave Background data from experiments probing both large and small scales. We assume that measured anisotropies are due not only to primary fluctuations but also, especially...

Magnetic fields from reionisation (2005)
Langer, Mathieu, Aghanim, Nabila, Puget, Jean-Loup
We present a complementary study to a new model for generating magnetic fields of cosmological interest. The driving mechanism is the photoionisation process by photons provided by the first luminous...
Cosmological Magnetogenesis driven by Radiation Pressure (2005)
Langer, Mathieu, Puget, Jean-Loup, Aghanim, Nabila
The origin of large scale cosmological magnetic fields remains a mystery, despite the continuous efforts devoted to that problem. We present a new model of magnetic field generation, based on local...
