C+detection of warm dark gas in diffuse clouds [PDF]

open access: yes, 2010
We present the first results of the Herschel open time key program, Galactic Observations of Terahertz C+ (GOT C+) survey of the [CII] 2P3/2–2P1/2 fine-structure line at 1.9 THz (158 μm) using the HIFI instrument on Herschel. We detected 146 interstellar

Magnetic Fields in the Southern Coalsack and Beyond

open access: yesThe Astronomical Journal
Starlight polarimetry, when combined with accurate distance measurements, allows for exploration of the three-dimensional structure of local magnetic fields in great detail.

Velocities of magneto-elastic and magneto-electron waves in dark molecular clouds

open access: yes, 2017
We present analytic and numerical estimates for group velocity of wave motions in two models of cold interstellar medium presumably constituting the interior of cores of magnetically supported dark molecular clouds.

Observation of Diffuse Galactic Light Near the Galactic Center with ONC-T on Board Hayabusa2

open access: yesThe Astrophysical Journal
Diffuse Galactic light (DGL) is starlight scattered by interstellar dust. In visible wavelengths, earlier studies observed DGL toward regions of low optical depth in high Galactic latitude, and show marginal consistency with a theoretical model assuming ...

Tidal Disruption of “Snow Clouds” by Unassociated Stars

open access: yesThe Astrophysical Journal
It has been suggested that star-forming galaxies may host a substantial, dark reservoir of gas in the form of planetary-mass molecular clouds that are so cold that H _2 can condense.

Massive Star Formation Starts in Subvirial Dense Clumps Unless Resisted by Strong Magnetic Fields

open access: yesThe Astrophysical Journal Letters
Knowledge of the initial conditions of high-mass star formation is critical for theoretical models, but are not well observed. Built on our previous characterization of a Galaxy-wide sample of 463 candidate high-mass starless clumps (HMSCs), here we ...

A Dense Molecular Ringlike Structure in Gaseous CO Depletion Region G34.74−0.12

open access: yesThe Astrophysical Journal Letters
We report the discovery of a dense molecular ringlike structure in a dense (10 ^5 cm ^−3 ), cold (parsec-scale CO depletion at a factor of 5), and young (10 ^4 yr) star-forming region G34.74−0.12, revealed by C ^18 O (2−1), HNC (1−0), and N _2 H ^+ (1−0)
