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…
HCN =4-3, HNC =1-0, =1-0, and =10-9 Maps of Galactic Center Region II.: Physical Properties of Dense Gas Clumps and Probability of Star Formation
Kunihiko Tanaka, Makoto Nagai, Kazuhisa Kamegai +2
We report a statistical analysis exploring the origin of the overall low star formation efficiency (SFE) of the Galactic central molecular zone (CMZ) and the SFE diversity among th…
Analytical expression of aperture efficiency affected by Seidel aberrations
Hiroaki Imada, Makoto Nagai
The effect of aberrations on the aperture efficiency has not been discussed analytically, though aberrations determine the performance of a wide field-of-view system. Expansion of…
Factorization of Antenna Efficiency of Aperture-type antenna: Beam Coupling and Two Spillovers
Makoto Nagai, Hiroaki Imada, Taishi Okumura
Antenna efficiency is one of the most important figures-of-merit of a radio telescope for observations especially at millimeter wavelengths or shorter wavelengths, even for a multi…
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…
