Presumed Detection of C5 Molecule in the Interstellar Medium
The Astrophysical Journal, 2022 The paper suggests the presence of the carbon chain C _5 molecule in translucent, interstellar H i clouds. This species, the only five atom interstellar molecule, observable in dark, translucent clouds, seems to be observable in reasonably dense clouds ...

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

Magnetic field morphology in interstellar clouds with the velocity gradient technique [PDF]
Nature Astronomy, 2019 Magnetic fields, while ubiquitous in many astrophysical environments, are challenging to measure observationally. Based on the properties of anisotropy of eddies in magnetized turbulence, the velocity gradient technique is a method synergistic to dust ...

Interstellar cloud collisions [PDF]
Monthly Notices of the Royal Astronomical Society, 1985 On decrit les resultats d'une simulation numerique en 3 dimensions de nuages interstellaires isothermes en l'absence de champs magnetiques. Les collisions, en general, ne donnent pas naissance a un ou plusieurs nuages.

Diffuse Interstellar Clouds [PDF]
Highlights of Astronomy, 1992 AbstractDiffuse clouds are interstellar objects through which starlight is not greatly extinguished. As a result, many studies rely on ultraviolet and visible measurements. The focus of this review is on spectroscopic work involving atomic and molecular lines. From these measurements, the physical and chemical makeup of the clouds is derived.

A Search for OH 18 cm Emission from Intermediate-velocity Gas at High Galactic Latitudes
The Astrophysical Journal, 2023 We present search results of 22 high-latitude (∣ b ∣ > 25°) sightlines for OH 18 cm emission using the 305 m radio telescope at the Arecibo Observatory. These sightlines appear in neutral hydrogen emission at intermediate velocities −90 ≤ V _LSR ≤ −20 km
