Molecular clouds in M82

open access: yesThe Astrophysical Journal, 1984
CO observations of the peculiar galaxy M82 have been made at 79 positions using the 14 m FCRAO telescope (HPBW = 50'') in order to obtain a fully sampled map of the central 2 kpc as well as the radial distribution of molecular gas out to 3 kpc along the major axis.

Atmospheric organic matter in clouds: exact masses and molecular formula identification using ultrahigh-resolution FT-ICR mass spectrometry [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
Clouds alter the composition of atmospheric aerosol by acting as a medium for interactions between gas- and particulate-phase substances. To determine the cloud water atmospheric organic matter (AOM) composition and study the cloud processing of aerosols,

Chemistry of Molecular Clouds [PDF]

open access: yesInternational Astronomical Union Colloquium, 1989
AbstractA discussion is presented of the chemistry of quiescent molecular clouds, and the effects of the presence of polycyclic aromatic hydrocarbon molecules and of cosmic-ray induced ultraviolet photons are examined. A comparison is made with the chemistry occurring in molecular clouds that are subjected to shocks and the differences between ...

Giant Molecular Clouds in M31. I. Molecular Cloud Properties [PDF]

open access: yesThe Astrophysical Journal, 2007
We present Berkeley Illinois Maryland Association (BIMA) millimeter interferometer observations of giant molecular clouds (GMCs) along a spiral arm in M31. The observations consist of a survey using the compact configuration of the interferometer and follow-up, higher-resolution observations on a subset of the detections in the survey.

Cloud-Based Software Architecture for Fully Automated Point-of-Care Molecular Diagnostic Device

open access: yesSensors, 2021
This paper proposes a cloud-based software architecture for fully automated point-of-care molecular diagnostic devices. The target system operates a cartridge consisting of an extraction body for DNA extraction and a PCR chip for amplification and ...

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.

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 ...

Possibilities for Methanogenic and Acetogenic Life in Molecular Clouds

open access: yesLife
According to panspermia, life on Earth may have originated from life forms transported through space from elsewhere. These life forms could have passed through molecular clouds, where the process of methanogenesis could have provided enough energy to ...
