We extend the work of Contaldi et al. [J. Cosmol. Astropart. Phys. 07 (2003) 002.] and derive analytical approximations for primordial power spectra arising from models inflation which include spatial curvature. These templates are independent any specific inflationary potential therefore illustrate provide insight into generic effects predictions curvature, manifesting as cutoffs oscillations ...

In the framework of studies CMB polarization and its Galactic foregrounds, angular power spectra thermal dust maps have revealed an intriguing E/B asymmetry a positive TE correlation. interpretation these observations, magnetized ISM clouds been treated as filamentary structures only; however, sheet-like shapes are also supported by observational theoretical evidence. this work, we study influe...
