Metallicity Dependence of Molecular Cloud Hierarchical Structure at Early Evolutionary Stages
Masato I. N. Kobayashi, Kazunari Iwasaki, Kengo Tomida +3
The formation of molecular clouds out of HI gas is the first step toward star formation. Its metallicity dependence plays a key role to determine star formation through the cosmic…
ACA CO() Mapping of the Nearest Spiral Galaxy M33. I. Initial Results and Identification of Molecular Clouds
Kazuyuki Muraoka, Ayu Konishi, Kazuki Tokuda +18
We present the results of ALMA-ACA 7 m-array observations in CO(), CO(), and CO() line emission toward the molecular-gas disk in the Local…
The JCMT BISTRO Survey: Studying the Complex Magnetic Field of L43
Janik Karoly, Derek Ward-Thompson, Kate Pattle +155
We present observations of polarized dust emission at 850 m from the L43 molecular cloud which sits in the Ophiuchus cloud complex. The data were taken using SCUBA-2/POL-2 on th…
CO Multi-line Imaging of Nearby Galaxies (COMING). XII. CO-to-H Conversion Factor and Dust-to-Gas Ratio
Atsushi Yasuda, Nario Kuno, Kazuo Sorai +8
We simultaneously measured the spatially-resolved CO-to-H conversion factor () and dust-to-gas ratio (DGR) in nearby galaxies on a kiloparsec scale. In this st…
Multi log-normal density structure in Cygnus-X molecular clouds: A fitting for N-PDF without power-law
Takeru Murase, Toshihiro Handa, Ren Matsusaka +6
We studied the H column density probability distribution function (N-PDF) based on molecular emission lines using the Nobeyama 45-m Cygnus X CO survey data. Using the DENDROGRA…
Giant molecular clouds and their Type classification in M74: Toward understanding star formation and cloud evolution
F. Demachi, Y. Fukui, R. I. Yamada +10
We investigated the giant molecular clouds (GMCs) in M74 (NGC 628), using data obtained from the PHANGS project. We applied the GMC Types according to the activity of star formatio…
Insights on the Sun birth environment in the context of star-cluster formation in hub-filament systems
Doris Arzoumanian, Sota Arakawa, Masato I. N. Kobayashi +7
Cylindrical molecular filaments are observed to be the main sites of Sun-like star formation, while massive stars form in dense hubs, at the junction of multiple filaments. The rol…
Diverse Molecular Structures Across The Whole Star-Forming Disk of M83: High fidelity Imaging at 40pc Resolution
Jin Koda, Akihiko Hirota, Fumi Egusa +23
We present high-fidelity CO(1-0) imaging of molecular gas across the full star-forming disk of M83, using ALMA's 12m, 7m, and TP arrays and the MIRIAD package. The data have a mass…
First BISTRO observations of the dark cloud Taurus L1495A-B10: the role of the magnetic field in the earliest stages of low-mass star formation
Derek Ward-Thompson, Janik Karoly, Kate Pattle +155
We present BISTRO Survey 850 μm dust emission polarisation observations of the L1495A-B10 region of the Taurus molecular cloud, taken at the JCMT. We observe a roughly triangular n…
