 Title: Galactic dust polarized emission at high latitudes and CMB polarization Authors: Sethi, S.K.Prunet, S.Bouchet, F.R. Issue Date: Mar-1998 Publisher: EDP Sciences Citation: Astronomy and Astrophysics, 1998, Vol.339, p187 Abstract: We estimate the dust polarized emission in our galaxy at high galactic latitudes, which is the dominant foreground for measuring CMB polarization using the high frequency instrument (HFI) aboard Planck surveyor. We compare it with the level of CMB polarization and conclude that, for angular scales $\le 1^{\circ}$, the scalar-induced CMB polarization and temperature-polarization cross-correlation are much larger than the foreground level at $\nu \simeq 100 GHz$. The tensor-induced signals seem to be at best comparable to the foreground level.} Description: Open Access URI: http://hdl.handle.net/2289/4924 ISSN: 0004-63611432-0746 (Online) Alternative Location: http://adsabs.harvard.edu/abs/1998astro.ph..3158Shttp://arxiv.org/abs/astro-ph/9803158http://dx.doi.org/ Copyright: 1998 EDP Sciences Appears in Collections: Research Papers (A&A)
