From inter-filamentary gas to filaments and hubs: gas flows in the Mon R2 hub-filament system
Jihye Hwang, Doris Arzoumanian, Yoshito Shimajiri +5
Hub-filament systems (HFSs) play an important role in the formation of massive stars and star clusters. Although the velocity structures along dense filaments have been studied, th…
Predicting dust temperature from molecular line data using machine learning
Tenta Dougome, Yoshito Shimajiri, Kazuya Saigo +4
We conducted experiments with machine learning techniques to construct dust temperature maps from the CO isotopologue molecular line data in the Orion A molecular cloud. In the cla…
Fragmenting Filaments and Evolving Cores -- Insights from Dust Polarisation Study of a filament in Northern Orion B
Kshitiz K. Mallick, Doris Arzoumanian, Satoko Takahashi +5
We present an analysis of polarised dust emission at 850 micron for a parsec long filament in the northern part of the Orion B molecular cloud. The region was observed by the JCMT…
The LMT 2 millimeter receiver system (B4R). II. Science demonstration observations toward Orion-KL/OMC-1
Teppei Yonetsu, Ryohei Kawabe, Yuki Yoshimura +26
We present the results of mapping and single-point spectral scans toward Orion-KL/OMC-1 performed as science demonstrations of a 2 mm SIS receiver, the Band 4 Receiver (B4R), insta…
The LMT 2 Millimeter Receiver System (B4R). I. Overview and Results of Science Demonstration
Ryohei Kawabe, Takeshi Sakai, Kunihiko Tanaka +30
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 alti…
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…
