Polarized X-rays Correlated with Short--Timescale Variability of Cygnus X-1
Kaito Ninoyu, Yuusuke Uchida, Shinya Yamada +4
We systematically investigate the variability of polarized X-rays on a timescale of a few seconds in the low/hard state of the black hole binary Cygnus X-1. The correlation between…
Fabrication of a 64-Pixel TES Microcalorimeter Array with Iron Absorbers Uniquely Designed for 14.4-keV Solar Axion Search
Yuta Yagi, Tasuku Hayashi, Keita Tanaka +7
If a hypothetical elementary particle called an axion exists, to solve the strong CP problem, a 57Fe nucleus in the solar core could emit a 14.4-keV monochromatic axion through the…
Simultaneous Millimeter-wave, Gamma-ray, and Optical Monitoring of the Blazar PKS 2326-502 During a Flaring State
J. C. Hood, A. Simpson, A. McDaniel +66
Including millimeter-wave (mm-wave) data in multi-wavelength studies of the variability of active galactic nuclei (AGN) can provide insights into AGN physics that are not easily ac…
Polarization angle requirements for CMB B-mode experiments. Application to the LiteBIRD satellite
P. Vielva, E. Martínez-González, F. J. Casas +68
A methodology to provide the polarization angle requirements for different sets of detectors, at a given frequency of a CMB polarization experiment, is presented. The uncertainties…
Scalar field couplings to quadratic curvature and decay into gravitons
Yohei Ema, Kyohei Mukaida, Kazunori Nakayama
Any field, even if it lives in a completely hidden sector, interacts with the visible sector at least via the gravitational interaction. In this paper, we show that a scalar field…
