23. Implications for Discovery of Strong Radial Magnetic Field at the Galactic Center

Prof. Qiu-he Peng (Department of Astronomy, Nanjing University)

An abnormal strong radial magnetic field near the Galactic Center (GC) is detected[1] . The lower limit of the radial magnetic field at r=0.12 pc from the GC is . Its Possible scientific significance are following: The black hole model at the GC is incorrect. The reason is very simple as follows. the radiations observed from the region neighbor of the GC are hardly emitted by the gas of...

1. Searching for patchy reionization from the cosmic microwave background

Reionization is a unique epoch in Cosmology and studies of the epoch of reionization (EoR) can tell us important information about ionization history, first luminous objects, and structure formation in the early Universe. However, the EoR is still poorly understood so far. At millimeter wavelengths, next-generation cosmic microwave background (CMB) experiments could detect the EoR signatures,...

The precision cosmic microwave background (CMB) measurement tells us a lot about the CMB propagation during the dark and reionization eras of the Universe. Beside a significant boost towards precision cosmology, this newly acquired understanding of the CMB signals can be turned into a powerful test of potential imprints on to the post-recombination temperature and ionization history...

32. Auto- and cross-correlation of the cosmic microwave background lensing and infrared background measured by Planck and Herschel

The primary objective of this paper is to measure the auto- and cross-power spectrum of the CIB from Herschel and CMB lensing from Planck. To achieve this, we analyze the Herschel-SPIRE HerMES Large Mode Survey field, which is about 280 square degree. we use Madmap algorithm to merged the the Herschel Level 1 timeline data as the CIB maps using by Herschel Interactive Processing Environment...
