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…

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…

Understanding the Star Formation Efficiency in Dense Gas: Initial Results from the CAFFEINE Survey with ArTéMiS

M. Mattern, Ph. André, A. Zavagno +9

Despite recent progress, the question of what regulates the star formation efficiency in galaxies remains one of the most debated problems in astrophysics. According to the dominan…

KAgoshima Galactic Object survey with Nobeyama 45-metre telescope by Mapping in Ammonia lines (KAGONMA): Discovery of parsec-scale CO depletion in the Canis Major star-forming region

Yushi Hirata, Takeru Murase, Junya Nishi +6

In observational studies of infrared dark clouds, the number of detections of CO freeze-out onto dust grains (CO depletion) at pc-scale is extremely limited, and the conditions for…

Dense gas and star formation in the Outer Milky Way

Jonathan Braine, Yan Sun, Yoshito Shimajiri +5

We present maps and spectra of the HCN(1-0) and HCO(1-0) lines in the extreme outer Galaxy, at galactocentric radii between 14 and 22 kpc, with the 13.7 meter Delingha telescop…

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…

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…

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…

Witnessing the fragmentation of a filament into prestellar cores in Orion B/NGC 2024

Y. Shimajiri, Ph. André, N. Peretto +3

Recent Herschel observations of nearby clouds have shown that filamentary structures are ubiquitous and that most prestellar cores form in filaments. Probing the density () and…

A low-mass hub-filament with double centre revealed in NGC2071-North

Vera Könyves, Derek Ward-Thompson, Yoshito Shimajiri +2

We present the first analysis in NGC2071-North as a resolved hub-filament featuring a double centre. This parsec-scale filament hub contains 500 $M_\odo…

Harmonic Bayesian prediction under alpha-divergence

Yuzo Maruyama, Toshio Ohnishi

We investigate Bayesian shrinkage methods for constructing predictive distributions. We consider the multivariate Normal model with a known covariance matrix and show that the Baye…
