A New 100-GHz Band Front-End System with a Waveguide-Type Dual-Polarization Sideband-Separating SIS Receiver for the NRO 45-m Radio Telescope
Taku Nakajima, Masayuki Kawamura, Kimihiro Kimura +8
We developed a waveguide-type dual-polarization sideband-separating SIS receiver system of the 100-GHz band for the 45-m radio telescope at the Nobeyama Radio Observatory, Japan. T…
A Molecular Line Observation toward Massive Clumps Associated with Infrared Dark Clouds
Takeshi Sakai, Nami Sakai, Kazuhisa Kamegai +4
We have surveyed the N2H+ J=1-0, HC3N J=5-4, CCS J_N=4_3-3_2, NH3 (J, K) = (1, 1), (2, 2), (3, 3), and CH3OH J=7-6 lines toward the 55 massive clumps associated with infrared dark…
Detection of HCO2+ toward the Low-Mass Protostar IRAS 04368+2557 in L1527
Nami Sakai, Takeshi Sakai, Yuri Aikawa +1
The millimeter-wave rotational emission lines (4(04)-3(03) and 5(05)-4(04)) of protonated carbon dioxide, HCO2+(HOCO+), has been detected toward the low-mass class 0 protostar IRAS…
