Observations of DNC and DCO $^{+}$ toward the $\int$ -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 $\int$ …

Q-band Line Survey Observations toward a Carbon-chain-rich Clump in the Serpens South Region

Kotomi Taniguchi, Fumitaka Nakamura, Sheng-Yuan Liu +17

We have conducted Q-band (30 GHz $-$ 50 GHz) line survey observations toward a carbon-chain emission peak in the Serpens South cluster-forming region with the extended Q-band (eQ)…

An ultra wide-band, high-sensitivity Q-band receiver for single-dish telescopes, eQ: rest frequency determination of CCS ( $J_{N}$ = $4_{3}$ - $3_{2}$ ) and SO ( $J_{N}$ = $1_{0}$ - $0_{1}$ ), and high-redshift CO ( $J$ = 1-0) detection

Fumitaka Nakamura, Chau-Ching Chiong, Kotomi Taniguchi +16

We report on the development and commissioning of a new Q-band receiver for the Nobeyama 45-m telescope, covering 30--50 GHz with a receiver noise temperature of about 15 K. We nam…
