Testing parity-violating physics from cosmic rotation power reconstruction
Toshiya Namikawa
We study the reconstruction of the cosmic rotation power spectrum produced by parity-violating physics, with an eye to ongoing and near future cosmic microwave background (CMB) exp…
BICEP3 focal plane design and detector performance
H. Hui, P. A. R. Ade, Z. Ahmed +56
BICEP3, the latest telescope in the BICEP/Keck program, started science observations in March 2016. It is a 550mm aperture refractive telescope observing the polarization of the co…
BICEP3 performance overview and planned Keck Array upgrade
J. A. Grayson, P. A. R. Ade, Z. Ahmed +56
BICEP3 is a 520 mm aperture, compact two-lens refractor designed to observe the polarization of the cosmic microwave background (CMB) at 95 GHz. Its focal plane consists of modular…
Testing statistics of the CMB B-mode polarization toward unambiguously establishing quantum fluctuation of vacuum
Maresuke Shiraishi, Chiaki Hikage, Ryo Namba +2
The B-mode polarization in the cosmic microwave background (CMB) anisotropies at large angular scales provides a smoking-gun evidence for the primordial gravitational waves (GWs).…
CMB Lensing Bispectrum from Nonlinear Growth of the Large Scale Structure
Toshiya Namikawa
We discuss detectability of the nonlinear growth of the large-scale structure in the cosmic microwave background (CMB) lensing. Lensing signals involved in CMB anisotropies have be…
Detecting Black-Hole Binary Clustering via the Second-Generation Gravitational-Wave Detectors
Toshiya Namikawa, Atsushi Nishizawa, Atsushi Taruya
The first discovery of the gravitational wave (GW) event, GW150914, suggests a higher merger rate of black-hole (BH) binaries. If this is true, a number of BH binaries will be obse…
BICEP2 / Keck Array VII: Matrix based E/B Separation applied to BICEP2 and the Keck Array
Keck Array, BICEP2 Collaborations, : +63
A linear polarization field on the sphere can be uniquely decomposed into an E-mode and a B-mode component. These two components are analytically defined in terms of spin-2 spheric…
Cosmology with the Square Kilometre Array by SKA-Japan
Daisuke Yamauchi, Kiyotomo Ichiki, Kazunori Kohri +8
In the past several decades, the standard cosmological model has been established and its parameters have been measured to a high precision, while there are still many of the funda…
