Molecular absorption lines toward the Galactic ISM detected at 89 GHz with VLBI
Keisuke Nakashima, Hiroshi Imai, Youngjoo Yun
As the first step to explore the Galactic foreground interstellar medium (ISM) with high angular resolution, we investigated the detectability of molecular absorption lines with ve…
Evidence for a gamma-ray molecular target in the enigmatic PeVatron candidate LHAASO J2108+5157
Eduardo de la Fuente, Ivan Toledano-Juárez, Kazumasa Kawata +11
To determine the nature of the PeVatron's emission (hadronic or leptonic), it is essential to characterize the physical parameters of the environment from where it originates. We u…
Nobeyama Survey of Inward Motions toward Cores in Orion Identified by SCUBA-2
Ken'ichi Tatematsu, You-Ting Yeh, Naomi Hirano +28
In this study, 36 cores (30 starless and 6 protostellar) identified in Orion were surveyed to search for inward motions. We used the Nobeyama 45 m radio telescope, and mapped the c…
Molecular Cloud Cores with High Deuterium Fractions: Nobeyama Mapping Survey
Ken'ichi Tatematsu, Gwanjeong Kim, Tie Liu +35
We present the results of on-the-fly mapping observations of 44 fields containing 107 SCUBA-2 cores in the emission lines of molecules, NH, HCN, and CCS at 8294 GHz…
Giant Molecular Cloud Formation at the Interface of Colliding Supershells in the Large Magellanic Cloud
Kosuke Fujii, Norikazu Mizuno, J. R. Dawson +8
We investigate the Hi envelope of the young, massive GMCs in the star-forming regions N48 and N49, which are located within the high column density Hi ridge between two kpc-scale s…
Wavefront sensor for millimeter/submillimeter-wave adaptive optics based on aperture-plane interferometry
Yoichi Tamura, Ryohei Kawabe, Yuhei Fukasaku +20
We present a concept of a millimeter wavefront sensor that allows real-time sensing of the surface of a ground-based millimeter/submillimeter telescope. It is becoming important fo…
