Relative Velocities between 13CO Structures within 12CO Molecular Clouds

The Astronomical Journal
Velocity fields of molecular clouds (MCs) can provide crucial information on the merger and split between clouds, as well as their internal kinematics and maintenance, energy injection and redistribution, and even star formation within clouds.

Discovery of Multiple Ultra-broad-velocity Molecular Features Associated with the W44 Molecular Cloud

The Astrophysical Journal Letters
We report the discovery of multiple compact molecular features exhibiting extremely broad velocity widths toward the W44 molecular cloud. Atacama Large Millimeter/submillimeter Array CO J = 3–2 data reveal eight “Petit-Bullets” surrounding the previously

Large aromatic molecules in the interstellar medium

, 2004
We propose a consistent explanation of the so-called "unidentified" IR emission bands of the Interstellar Medium observed at 3.3 - 6.2 - 7.7 - 8.6- 11.3 μm. Following Sellgren (1984), we consider the transient heating of Very Small Grains (∼ 50 atoms) to

An Ultraviolet Study of CO Chemistry in the Magellanic Clouds

The Astronomical Journal
How does molecular cloud chemistry change with metallicity? In this work, we study the relation between molecular hydrogen (H _2 ) and carbon monoxide (CO) at 1/2 and 1/5 solar metallicity using ultraviolet absorption spectroscopy obtained as part of the

Lifetimes of Certain Interstellar Organic Molecules [PDF]

, 1981
78-79Lifetimes of some organic molecules such as H2CO, H2CS, HCOOH, CH3NH2, CH3OH and CH3CHO in interstella, space against photodissociation and chemical reactions in the gas phase have been calculated.

Regarding the Detection of Interstellar C4 and C5 Molecules

The Astrophysical Journal
Analysis of very high signal-to-noise ratio (S/N) spectra of reddened stars allowed us to determine an upper limit (UL) of the column density N (C _4 ).
