GroundBIRD is a millimeter-wave telescope to observe the polarization patterns of the cosmic microwave background (CMB). The target science topics are primordial gravitational waves from cosmic inflation and reionization optical depth. Therefore, thi

The cosmic microwave background (CMB) radiation is an afterglow of the Big Bang. It contains the crucial keys to understand the beginning of the universe. In particular, the odd-parity patterns of CMB polarization, B-modes, at more than degree-scale,

Polarized patterns in the cosmic microwave background (CMB) radiation contains rich knowledge for early stage of the universe. In particular their odd-parity patterns at large angular scale (> 1°), primordial B-modes, are smoking-gun evidence for th

Our understanding of physics at very early Universe, as early as 10−35 s after the Big Bang, relies on the scenario known as the inflationary cosmology. Inflation predicts a particular polarization pattern in the cosmic microwave background, known

An experiment to search for hypothetical neutralino dark matter using lithium fluoride bolometer array is underway. This bolometer array consists of eight pieces of 21 g LiF bolometers. Fluorine has large sensitivity for axially coupled neutralino co

The performance of a 21-g lithium fluoride bolometer is presented. The background spectrum was measured in the surface laboratory. We derive an exclusion plot for the spin-dependent coupled Weakly Interacting Massive Particles (WIMPs) cross section.

We developed a bolometer with a 0.5 g CdTe absorber using a high-sensitivity NTD germanium thermistor. An energy resolution of 24 keV (FWHM) is obtained for 0.66 to 1.8 MeV γ-rays. It shows a good linearity of the response in the energy range betwee

A back-to-back electron-positron pair is searched for in spontaneous-fission disintegration of 252Cf. The emission of such a pair, if observed, might be a manifestation of production and prompt decay of a heretofore unknown neutral particle. The emis

We searched for anomalous γ rays in 35 S decay as a possible explanation for the kink in the β-decay spectrum, which is claimed to be due to the emission of the heavy 17 keV neutrino. The intensity and spectrum of γ rays we observed are consistent
