WMAP 7 year constraints on CPT violation from large angle CMB anisotropies

2011/10/18
We constrain the rotation angle $\alpha$ of the linear polarization of CMB photons using the large angular scale (up to $\sim 4^\circ$) signal in WMAP 7 year data. At these scales, the CMB polarizatio...

Shocks that arise from baryonic in-fall and merger events during
the structure formation are believed to be a source of cosmic rays. These "struc-
ture formation cosmic rays" (SFCRs) would essential...
