CO Structures with Narrow Lines in Nearby Quiescent Regions

The Astrophysical Journal Letters
Using CO data from Phase I of the Milky Way Imaging Scroll Painting survey, we present a systematic study of molecular structures with narrow lines.

Are Supernovae Responsible for the Gamma Ray Spectrum from the Galactic Center?

Acta Polytechnica CTU Proceedings, 2014
We discuss the supernova remnants distribution as a function of the galactic longitude and compare their positions to that of the detected TeV gamma ray sources. A large fraction of these sources either coincide or a close by known supernova remnants. If

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Observational Constraints for Modeling Diffuse Molecular Clouds [PDF]

Proceedings of the International Astronomical Union, 2013
AbstractGround-based and space-borne observations of diffuse molecular clouds suggest a number of areas where further improvements to modeling efforts is warranted. I will highlight those that have the widest applicability. The range in CO fractionation caused by selective isotope photodissociation, in particular the large 12C16O/13C16O ratios observed

Diffusive versus Free-streaming Cosmic-Ray Transport in Molecular Clouds [PDF]

The Astrophysical Journal, 2019
Abstract Understanding the cosmic-ray (CR) ionization rate is crucial in order to simulate the dynamics of molecular clouds, and interpret the chemical species observed in these objects. Calculating the CR ionization rate requires both accurate knowledge of the spectrum of MeV to GeV protons at the edge of the cloud as well as a model ...

Mutual influence of supernovae and molecular clouds [PDF]

, 2014
International audienceContext. Molecular clouds are known to be turbulent and strongly affected by stellar feedback. Moreover, stellar feedback is believed to drive turbulence at large scales in galaxies.Aims.

Examining Turbulence in Galactic Molecular Clouds. II. Turbulence Cascade Beyond the Scale of Giant Molecular Clouds

The Astrophysical Journal
We use ^12 CO ( J = 1–0) data from the MWISP survey to investigate turbulence in a ∼kiloparsec-scale segment of the Local Arm. By slicing the position–position–velocity cube into narrow layers that follow the Galactic-rotation trend in the L – V diagram,

Interstellar shocks and molecular CH/+/ in diffuse clouds

The Astrophysical Journal, 1980
The influence of shocks on the abundances of molecules in diffuse interstellar clouds is investigated with special emphasis on molecular CH/sup +/. Idealized shocks with plausible parameters are found to produce column densities for CH/sup +/ in the hot, postshock gas which are comparable with measured values in interstellar clouds (up to about 10/sup ...
