Planck dust modeling has been released and shows consistency with the assumptions of BICEP2, although this remains an unsupported assumption. The BICEP2 results hinge on the magnetic properties of dust lanes, particularly iron grains, which could mimic the B Mode polarization of the Cosmic Microwave Background (CMB). The DL model by Li & Draine (2001) utilizes a carbonaceous-silicate grain model that effectively reproduces interstellar extinction and IR emission, yet it may not address the specific dust types necessary to validate the BICEP2 findings. The discussion highlights the need for further investigation into the polarization effects of Earth's atmosphere on light.
PREREQUISITESAstronomers, astrophysicists, and researchers interested in cosmic polarization effects and the implications of dust modeling on CMB studies.
the authors would not seem to be looking at the relevant type of dust crucial to verify or otherwise the BICEP2 result.Li & Draine (2001) developed a carbonaceous-silicate grain model that has been quite successful in reproducing observed interstellar extinction, scattering, and IR emission. DL presented an updated physical dust model, extensively used to model starlight absorption and IR emission. The DL dust model employs a mixture of amorphous silicate grains and carbonaceous grains.
