The Molecular Cloud Lifecycle. [PDF]

open access: yesSpace Sci Rev, 2020
AbstractGiant molecular clouds (GMCs) and their stellar offspring are the building blocks of galaxies. The physical characteristics of GMCs and their evolution are tightly connected to galaxy evolution. The macroscopic properties of the interstellar medium propagate into the properties of GMCs condensing out of it, with correlations between e.g.

Ice-nucleating particles in northern Greenland: annual cycles, biological contribution and parameterizations [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Ice-nucleating particles (INPs) can initiate ice formation in clouds at temperatures above −38 ∘C through heterogeneous ice nucleation. As a result, INPs affect cloud microphysical and radiative properties, cloud lifetime, and precipitation behavior and

Nebula-Relay Hypothesis: The Chirality of Biological Molecules in Molecular Clouds

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The chiral puzzle of biological molecules is thought to be closely related to the origin of life and is still a mystery so far. Previously, we proposed a new model on the origin of life, Nebula-Relay hypothesis, which assumed that the life on Earth ...

Anatomy of Orion Molecular Clouds—The Astrochemistry Perspective/Approach

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The Orion molecular cloud (OMC) complex is the nearest and perhaps the best-studied giant molecular cloud complex within which low-mass and massive star formation occur. A variety of molecular species, from diatomic molecules to complex organic molecules

A Velocity Structure Analysis of Giant Molecular Cloud Associated with HII Region S152 [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2005
S152 is a small bright emission nebula located in the Perseus arm. Its optical diameter corresponds to 1.5 pc for an adopted distance 3.5 kpc. However, S152 is a part of a giant molecular cloud complex, which consists of several dense cores, containing ...
