New Constraints On Cosmic Polarization Rotation Including SPTpol B-mode Polarization Observations
W. -P. Pan, S. di Serego Alighieri, W. -T. Ni +1
We present an update of the cosmic polarization rotation (CPR) constraint from the recent SPTpol measurements of sub-degree B-mode polarization in the cosmic microwave background (…
New constraints on cosmic polarization rotation from the ACTPol cosmic microwave background B-Mode polarization observation and the BICEP2 constraint update
Hsien-Hao Mei, Wei-Tou Ni, Wei-Ping Pan +2
Recently ACTPol has measured the cosmic microwave background (CMB) B-mode and E-mode polarizations and obtained TE, EE, BB, TB and EB power spectra in the multipole range 225-8725.…
New Constraints on Cosmic Polarization Rotation from B-Mode Polarization in Cosmic Microwave Background
Sperello di Serego Alighieri, Wei-Tou Ni, Wei-Ping Pan
STPpol, POLARBEAR and BICEP2 have recently measured the cosmic microwave background (CMB) B-mode polarization in various sky regions of several tens of square degrees and obtained…
Solar-system tests of the inflation model with a Weyl term
Wei-Tou Ni
Recently, there has been an interest in inflation and modified gravity with a Weyl term added to the general-relativistic action (N. Derulle, M. Sasaki, Y. Sendouda and A. Youssef,…
Dark energy, co-evolution of massive black holes with galaxies, and ASTROD-GW
Wei-Tou Ni
The detection of low frequency band (100 nHz-100 mHz) and very low frequency band (300 pHz-100 nHz) gravitational waves (GWs) is important for exploration of the equation of state…
Gravitational waves, dark energy and inflation
Wei-Tou Ni
In this paper we first present a complete classification of gravitational waves according to their frequencies: (i) Ultra high frequency band (above 1 THz); (ii) Very high frequenc…
