Linear Analyses of Thermal Instability in Stratified Medium

Izumi Seno, Shu-ichiro Inutsuka, Jiro Shimoda

Thermal instability in the circum-galactic medium (CGM) can be responsible for the existence of cold clouds (e.g., high-velocity clouds) embedded in a hot diffuse medium (e.g., X-r…

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…

Modeling of Collisional Outcomes Based on Impact Simulations of Mars-sized Bodies

Hiroshi Kobayashi, Hidekazu Tanaka, Yukihiko Hasegawa +1

We investigate the outcomes of collisions between Mars-sized bodies through smooth particle hydrodynamics (SPH) simulations, focusing on the transitions among ``merging'', ``hit-an…

Interplay between Escaping Cosmic Rays and Interstellar Medium: Driving of Galactic Winds and Shaping the Local Proton Spectrum

Jiro Shimoda, Katsuaki Asano, Shu-ichiro Inutsuka

We study the effects of escaping cosmic rays (CRs) on the interstellar medium (ISM) around their source with spherically symmetric CR-hydrodynamical simulations taking into account…

Evolution of magnetized hub-filament systems: Comparing the observed properties of W3(OH), W3 Main, and S 106

M. S. N. Kumar, D. Arzoumanian, S. Inutsuka +2

In this study, we examine three cluster-forming hub-filament systems (HFS) - W3(OH), W3 Main, and S 106 - spanning evolutionary stages from early to advanced, with a focus on their…

The JCMT BISTRO Survey: Unveiling the Magnetic Fields around Galactic Center

Meng-Zhe Yang, Shih-Ping Lai, Janik Karoly +40

We acquired 450 μm and 850 μm dust continuum polarization observations toward the inner region of the Central Molecular Zone (CMZ) as part of the B-Fields In Star-Forming Region Ob…
