A Cloud-Scale View of the Molecular Gas Disk in the Whirlpool Galaxy and Beyond [PDF]

EPJ Web of Conferences, 2022
The nearby galaxy M51 (also known as the Whirlpool galaxy) hosts an iconic grand-design spiral pattern and both IRAM facilities conducted the first cloud-scale (∼50 pc resolution) survey of the molecular gas reservoir across a the disk of a massive star ...

Waves on the surface of the Orion molecular cloud [PDF]

, 2010
Massive stars influence their parental molecular cloud, and it has long been suspected that the development of hydrodynamical instabilities can compress or fragment the cloud. Identifying such instabilities has proved difficult.

The Molecular Cloud Lifecycle. [PDF]

Space 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]

Atmospheric 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

Frontiers 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

Frontiers 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]

Journal 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 ...
