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, Masato Hagimoto et autres

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 address this, we present the development of the Far-Infrared Nebular Emission Receiver (FINER) for the Large Millimeter …

New geometrical algorithm for the ALMA single-dish pipeline to identify pointing outlier data and its impact on the ALMA operation

Takeshi Nakazato, H. Ezawa, Kanako Sugimoto, Karl Torstensson et autres

TheAtacama Large Millimeter/submillimeter Array (ALMA) delivers reduced, calibrated, and quality-assessed data products to its users. In ALMA, the control software excludes data with the pointing direction deviating from predefined trajectory. However, there are several cases that this mechanism does not work. To …

Digging into the Interior of Hot Cores with ALMA (DIHCA). VI. The Formation of Low-mass Multiple Systems in High-mass Cluster-forming Regions

Qiuyi Luo, Patricio Sanhueza, Stella S. R. Offner, Fernando A. Olguin et autres

Abstract Most stars form in multiple systems, with profound implications in numerous astronomical phenomena intrinsically linked to multiplicity. However, our knowledge about the process of how multiple stellar systems form is incomplete and biased toward nearby molecular clouds forming only low-mass stars, …

Digging into the Interior of Hot Cores with ALMA (DIHCA). VII. Disk Candidates around High-mass Stars and Evidence of Anisotropic Infall

Fernando A. Olguin, Patricio Sanhueza, Yoko Oya, Adam Ginsburg et autres

Abstract We study the kinematics of condensations in 30 fields forming high-mass stars with the Atacama Large Millimeter/submillimeter Array at a high resolution of ∼ 0 . ″ 08 on average (∼230 au). The presence of disks is important for feeding high-mass …

A spectral-line survey of CIT 6 between 30 and 50 GHz with the eQ receiver at NRO 45 m

Quang Nguyen-Luong, Fumitaka Nakamura, Kotomi Taniguchi, Dinh-V-Trung et autres

Context. At the end of the long H-burning phase (main sequence), low-mass to intermediate-mass stars evolve into asymptotic giant branch (AGB) stars that can have carbon-rich envelopes depending on the initial C/O ratio. In their circumstellar envelopes (CSEs), dust particles and molecules …

Digging into the Interior of Hot Cores with ALMA (DIHCA). VII. Disk candidates around high-mass stars and evidence of anisotropic infall

Fernando A. Olguin, Patricio Sanhueza, Yoko Oya, Adam Ginsburg et autres

We study the kinematics of condensations in 30 fields forming high-mass stars with ALMA at a high-resolution of ~0.08'' on average (~230 au). The presence of disks is important for feeding high-mass stars without feedback halting growth as their masses increase. In …

The LMT 2 Millimeter Receiver System (B4R). I. Overview and Results of Science Demonstration

Ryohei Kawabe, Takeshi Sakai, Kunihiko Tanaka, Akio Taniguchi et autres

Abstract We report on the results of the on-sky test and science demonstration conducted with the 2 mm receiver system, B4R, on the 50 m Large Millimeter Telescope (LMT), located at an altitude of 4600 m in Mexico. The B4R receiver was …
