The Formation of Milky Way “Bones”: Ubiquitous HI Narrow Self-absorption Associated with CO Emission
The Astrophysical Journal LettersLong and skinny molecular filaments running along Galactic spiral arms are known as “bones,” since they make up the skeleton of the Milky Way. However, their origin is still an open question.

Detection of an optical filament in the Monogem Ring
, 2005 The Monogem Ring is a huge bright soft X-ray enhancement with a diameter of ~ 25$\degr$. This 0.3 kpc distant structure is a peculiar Galactic supernova remnant in that it is obviously visible only in X-rays, due to its expansion into a region of ...

Monthly Notices of the Royal Astronomical Society, 2019 We present a study of the relative orientation between the plane-of-the-sky magnetic field and the filamentary structures hosting the Planck Galactic Cold Clumps. In our analysis, the magnetic field angles are obtained from the sub-millimeter linear polarization measurements by the Planck satellite.

Wave Structure within HI Filaments at High Galactic Latitude and the Nature of “Clouds” in Interstellar Space [PDF]
Symposium - International Astronomical Union, 1991 Large amplitude waves have been found in the morphology and velocity patterns of several long filaments of HI at high latitude. HI in the filaments is controlled by magnetic fields and the velocity patterns and morphology bear the hallmarks of Alfvén waves.

Cosmic-Ray Feedback on Bistable Interstellar Medium Turbulence
The Astrophysical JournalWhile cosmic rays ( E ≳ 1 GeV) are well coupled to a galaxy’s interstellar medium (ISM) at scales of L > 100 pc, adjusting stratification and driving outflows, their impact on small scales is less clear.

Magnetic fields of our Galaxy on large and small scales
, 2007 Magnetic fields have been observed on all scales in our Galaxy, from AU to kpc. With pulsar dispersion measures and rotation measures, we can directly measure the magnetic fields in a very large region of the Galactic disk.

Cluster Formation in a Filamentary Cloud: The Case of the Stellar Cluster NGC 2316
The Astronomical JournalWe present a multiwavelength analysis of the star cluster NGC 2316 and its surroundings. We estimated the physical parameters of the NGC 2316 cluster, including its shape (elongated), size ( R _cluster = 0.4 pc), distance (1.3 ± 0.3 kpc), and minimum ...

Triggering star formation by both radiative and mechanical active galactic nucleus feedback
, 2013 We perform two dimensional hydrodynamic numerical simulations to study the positive active galactic nucleus feedback which triggers, rather than suppresses, star formation. Recently, it was shown by Nayakshin et al. and Ishibashi et al.

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