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…
An AGN in the Antennae galaxies ?
Shinya Komugi, Toshiki Saito, Tomonari Michiyama +5
Time variability is a strong probe of energetic phenomena which occur at small spatial scales, like Active Galactic Nuclei (AGN). We use ALMA observations at 100 GHz executed over…
Observations of DNC and DCO toward the -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 …
A multi-scale molecular and atomic gas view on the HII region N113 in the Large Magellanic Cloud:Evidence for high-mass star formation triggered by supersonically-colliding HI flows
Rin I. Yamada, Kazuki Tokuda, Yasuo Fukui +15
The Large Magellanic Cloud (LMC) exhibits vigorous high-mass star formation, including the HII regions 30~Dor that is the most active site of star formation in the local group. The…
ALMA Band 9 CO(6--5) Reveals a Warm Ring Structure Associated with the Embedded Protostar in the Cold Dense Core MC 27/L1521F
Kazuki Tokuda, Mitsuki Omura, Naoto Harada +9
Infall and outflows, coupled with magnetic fields, rapidly structure the gas around newborn protostars. Shocks from interacting components encode the temperature and density distri…
Cloud-Cloud Collisions Induce Filament-Mediated Super Star Cluster Formation in the Antennae Overlap Region: Evidence from ALMA and JWST
Tomonari Michiyama, Toshiki Saito, Kouichiro Nakanishi +5
The formation of super star clusters (SSCs) in galaxies remains a fundamental yet unresolved problem. Among the proposed mechanisms, cloud-cloud collisions (CCCs) have been suggest…
