Internal 1000 au Scale Structures of the R CrA Cluster-forming Cloud. I. Filamentary Structures

The Astrophysical Journal
We report Atacama Large Millimeter/submillimeter Array/Atacama Compact Array observations of a high-density region of the Corona Australis cloud forming a young star cluster, and the results of resolving internal structures. In addition to embedded Class

Abundances of Chemical Elements in Open Star Clusters as Indicators of their Nature

Open Astronomy, 2015
Applying a compilled catalog, we find that the relative abundances of α-elements in open clusters and in field stars of the thin disk of the Galaxy show different dependencies on metallicity, age and parameters of their Galactic orbits.

Evidence for Spatially Distinct Galactic Dust Populations

The Astrophysical Journal
We present an implementation of a Bayesian mixture model using Hamiltonian Monte Carlo techniques to search for the spatial separation of Galactic dust populations. Utilizing intensity measurements from the Planck High Frequency Instrument, we apply this

Dark ice chemistry in interstellar clouds [PDF]

, 2020
This thesis is largely an experimental study on the formation of solid-state simple and complex organic molecules in the H2O-rich and CO-rich ice phases of dense interstellar clouds and dark cores. Astronomical ice observations are also presented and are

Filamentary Network and Magnetic Field Structures Revealed with BISTRO in the High-mass Star-forming Region NGC 2264: Global Properties and Local Magnetogravitational Configurations

The Astrophysical Journal
We report 850 μ m continuum polarization observations toward the filamentary high-mass star-forming region NGC 2264, taken as part of the B -fields In STar forming Regions Observations large program on the James Clerk Maxwell Telescope. These data reveal

On the Stability of Interstellar Neutral Hydrogen Clouds at Large Z-heights

The Astrophysical Journal
Galactic neutral hydrogen (H i ) data drawn from several large-scale surveys have been used to study 32 small clouds found between Galactic longitudes 70° and 140° and latitudes −20° and −45°.

A Multiscale Molecular and Atomic Gas View on the H ii Region N113 in the Large Magellanic Cloud: Evidence for High-mass Star Formation Triggered by Supersonically Colliding H i Flows

The Astrophysical Journal
The Large Magellanic Cloud (LMC) exhibits vigorous high-mass star formation, including the H ii regions of 30 Dor, which is the most active site of star formation in the Local Group.

Cloud-cloud collisions in the interstellar medium

The Astrophysical Journal, 1980
Results are presented from time-dependent numerical simulations of cloud-cloud collisions in the interstellar medium. Special emphasis is placed on physically detailed models of cloud collisions. The numerical simulations include heating, cooling, thermal conductivity, self-gravity, and molecule formation; magnetic fields have been neglected.
