Development Status of Wideband Millimeter-Wave Receivers for LMT-FINER
Haoran Kang, Takafumi Kojima, Takeshi Sakai +4
Spectroscopic observations of the far-infrared [O III] and [C II] lines present a pathway to explore the mechanisms of the emergence of massive galaxies in the epoch of reionizatio…
Development of a new wideband heterodyne receiver system for the Osaka 1.85-m mm-submm telescope -- Receiver development & the first light of simultaneous observation in 230GHz and 345GHz bands with an SIS-mixer with 4-21GHz IF output
Sho Masui, Yasumasa Yamasaki, Hideo Ogawa +22
We have developed a wideband receiver system for simultaneous observations in CO lines of J = 2-1 and J = 3-2 transitions using the Osaka 1.85-m mm-submm telescope. As a frequency…
FINER: development of the wideband millimeter-wave receiver system and preparations for first light on the Large Millimeter Telescope
Akio Taniguchi, Yoichi Tamura, Takeshi Sakai +38
The recent discovery of an excess of luminous galaxies in the early Universe necessitates sensitive and wideband millimeter spectroscopy to understand their rapid growth. To addres…
Observations of DNC and DCO toward the -shaped Filament and Starless Cores in the Orion Molecular Clouds
Ken'ichi Tatematsu, Atsushi Nishimura, Hideo Ogawa +25
Although the deuterium fraction is known to be a powerful evolutionary tracer, its variation within individual molecular cloud cores is still poorly understood. The northern …
Fabrication and characterization of Nb/Al-AlN /Nb superconducting tunnel junctions
Alexey Pavolotsky, François Joint, Udupa Sujit Manjunatha +6
We report a Nb/Al-AlN /Nb superconducting tunnel junction process in which the AlN barrier is formed by plasma nitridation using a compact microwave electron-cyclotron-resonance (E…
Development of the new multi-beam receiver and telescope control system for NASCO
Atsushi Nishimura, Akio Ohama, Kimihiro Kimura +59
We report the current status of the NASCO (NAnten2 Super CO survey as legacy) project which aims to provide all-sky CO data cube of southern hemisphere using the NANTEN2 4-m submil…
