Planar near-field measurements of specular and diffuse reflection of millimeter-wave absorbers
Fumiya Miura, Hayato Takakura, Yutaro Sekimoto +4
Mitigating the far sidelobes of a wide field-of-view telescope is one of the critical issues for polarization observation of the cosmic microwave background. Since even small refle…
Overview of the Medium and High Frequency Telescopes of the LiteBIRD satellite mission
L. Montier, B. Mot, P. de Bernardis +232
LiteBIRD is a JAXA-led Strategic Large-Class mission designed to search for the existence of the primordial gravitational waves produced during the inflationary phase of the Univer…
LiteBIRD: JAXA's new strategic L-class mission for all-sky surveys of cosmic microwave background polarization
M. Hazumi, P. A. R. Ade, A. Adler +233
LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection, is a space mission for primordial cosmology and…
Concept Design of Low Frequency Telescope for CMB B-mode Polarization satellite LiteBIRD
Y. Sekimoto, P. A. R. Ade, A. Adler +232
LiteBIRD has been selected as JAXA's strategic large mission in the 2020s, to observe the cosmic microwave background (CMB) -mode polarization over the full sky at large angular…
GroundBIRD : A CMB polarization experiment with MKID arrays
Kyungmin Lee, Jihoon Choi, Ricardo Tanausú Génova-Santos +31
GroundBIRD is a ground-based experiment for the precise observation of the polarization of the cosmic microwave background (CMB). To achieve high sensitivity at large angular scale…
Updated design of the CMB polarization experiment satellite LiteBIRD
H. Sugai, P. A. R. Ade, Y. Akiba +216
Recent developments of transition-edge sensors (TESs), based on extensive experience in ground-based experiments, have been making the sensor techniques mature enough for their app…
A wide field-of-view crossed Dragone optical system using the anamorphic aspherical surfaces
Shingo Kashima, Masashi Hazumi, Hiroaki Imada +4
A side-fed crossed Dragone telescope provides a wide field-of-view. This type of a telescope is commonly employed in the measurement of cosmic microwave background (CMB) polarizati…
Analysis of characteristics of Al MKID resonators
Takashi Noguchi, Agnes Dominjon, Yutaro Sekimoto
We have prepared two kinds of Al resonators using thin films made by evaporation or sputtering and studied temperature behavior of their quality factors and resonance frequencies w…
Mission design of LiteBIRD
T. Matsumura, Y. Akiba, J. Borrill +66
LiteBIRD is a next-generation satellite mission to measure the polarization of the cosmic microwave background (CMB) radiation. On large angular scales the B-mode polarization of t…
N2H+ and HC3N Observations of the Orion A Cloud
K. Tatematsu, R. Kandori, T. Umemoto +1
The ``integral-shaped filament'' of the Orion A giant molecular cloud was mapped in N2H+, and its northern end, the OMC-2/3 region was observed also in HC3N and CCS. The N2H+ distr…
Discovery of Diffuse X-ray Emission in One of the Nearest Massive Star-Forming Regions NGC 2024
Yuichiro Ezoe, Motohide Kokubun, Kazuo Makishima +2
A deep 75 ks {\it Chandra} ACIS--I data of NGC 2024 was analyzed, aiming at a search for diffuse X-ray emission in this one of the most nearby (415 pc) massive star-forming regions…
N2H+ Observations of Molecular Cloud Cores in Taurus
K. Tatematsu, T. Umemoto, R. Kandori +1
N2H+ observations of molecular cloud cores in Taurus with the Nobeyama 45 m radio telescope are reported. We compare ``cores with young stars'' with ``cores without young stars''.…
Atomic Carbon and CO Isotope Emission in the Vicinity of DR15
T. Oka, S. Yamamoto, M. Iwata +17
We present observations of the 3P1-3P0 fine structure transition of atomic carbon [CI], the J=3-2 transition of CO, as well as of the J=1-0 transitions of 13CO and C18O toward DR15…
Discovery of X rays from Class 0 protostar candidates in OMC-3
Yohko Tsuboi, Katsuji Koyama, Kenji Hamaguchi +4
We have observed the Orion Molecular Clouds 2 and 3 (OMC-2 and OMC-3) with the Chandra X-ray Observatory (CXO). The northern part of OMC-3 is found to be particularly rich in new X…
