Submillimeter and Far-Infrared Polarimetric Observations of Magnetic Fields in Star-Forming Regions

open access: yesFrontiers in Astronomy and Space Sciences, 2019
Observations of star-forming regions by the current and upcoming generation of submillimeter polarimeters will shed new light on the evolution of magnetic fields over the cloud-to-core size scales involved in the early stages of the star formation ...

Molecular Clouds in External Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1985
Observations of the large-scale distribution of molecular clouds in external galaxies offer a unique opportunity for investigating galactic evolution. New generations of stars form in these dense regions, and the most massive of these stars recycle their processed interiors into the interstellar medium.

OBSERVATIONS OF NON TYPICAL MASERS AT THE RT-22 RADIO TELESCOPE IN 2004–2013

open access: yesRadio Physics and Radio Astronomy, 2017
Purpose: Some peculiarities of emission of Class I methanol masers on the 80–71A+ transition at 95 GHz in sources closely associated with protostar-forming regions and in supernova remnants are studied.

The energetics of molecular clouds. III - The S235 molecular cloud

open access: yesThe Astrophysical Journal, 1981
The molecular cloud associated with the S235 H II region has been studied by means of molecular lines and near-infrared observations. The cloud consists of two components, one of which partly surrounds the S235 H II region. The other component contains a dense, hot region of active star formation, marked by self-reversed CO profiles, compact H II ...

FORMATION OF MASSIVE MOLECULAR CLOUD CORES BY CLOUD-CLOUD COLLISION [PDF]

open access: yesThe Astrophysical Journal, 2013
Recent observations of molecular clouds around rich massive star clusters including NGC3603, Westerlund 2, and M20 revealed that the formation of massive stars could be triggered by a cloud-cloud collision. By using three-dimensional, isothermal, magnetohydrodynamics simulations with the effect of self-gravity, we demonstrate that massive ...

ON THE THEORY OF THE OF-CENTRAL EXPLOSION IN A SPHERICALLY STRATIFIED MEDIUM

open access: yesRadio Physics and Radio Astronomy, 2015
Аn analytical solution for a spherically stratified medium is constructed on the strength of an earlier obtained exact solution of Kompaneets equation for the shock front in a planar stratified medium with the density changing as the hyperbolic tangent ...

Characterizing the 3D Structure of Molecular Cloud Envelopes in the Cloud Factory Simulations

open access: yesThe Astrophysical Journal
We leverage recent numerical simulations of highly resolved star-forming regions in a Milky Way–like galaxy to explore the nature of extended gaseous envelopes around molecular clouds.

Molecular Clouds in the Galactic Plane from l = [59.°75, 74.°75] and b = [−5.°25, +5.°25]

open access: yesThe Astrophysical Journal Supplement Series, 2023
In this paper we present the distribution of molecular gas in the Milky Way Galactic plane from l = [59.75, 74.75]° and b = [−5.25, +5.25]°, using the MWISP ^12 CO/ ^13 CO/C ^18 O emission-line data.
