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 $\int$ …

Head-tail molecular clouds falling onto the Milky Way disk

Mikito Kohno, Yasuo Fukui, Takahiro Hayakawa +13

We report discovery of two CO clouds which are likely falling down to the Galactic plane at more than $35$ km s $^{- 1}$ . The clouds show head-tail distributions elongated perpendicu…

Infrared bubble recognition in the Milky Way and beyond using deep learning

Shimpei Nishimoto, Toshikazu Onishi, Atsushi Nishimura +9

We propose a deep learning model that can detect Spitzer bubbles accurately using two-wavelength near-infrared data acquired by the Spitzer Space Telescope and JWST. The model is b…
