Prebiotic Organic Chemistry of Diketopiperazines
Asian Journal of Organic Chemistry, Volume 15, Issue 4, April 2026.Diketopiperazines (DKPs) are considered essential in many life forms, but their prebiotic importance has not been fully understood. This review aims to discuss prebiotic organic chemistry for experimentally and computationally simulated reactions involving DKPs. ABSTRACT Even though the significance of amino acids and polypeptides is well recognized in

Grains charges in interstellar clouds [PDF]
, 1989 The charge of cosmic grains could play an important role in many astrophysical phenomena. It probably has an influence on the coagulation of grains and more generally on grain-grain collisions, and on interaction between charged particles and grains ...

The Origin of the Cluster of Local Interstellar Clouds
The Astrophysical JournalThe interstellar medium within ≈15 pc of the Sun consists of a complex of 15 diffuse, partially ionized clouds. Located within the Local Bubble, these clouds, known as the Cluster of Local Interstellar Clouds (CLIC), constitute the interstellar ...

INTERSTELLAR CLOUDS BY SEARCHLIGHT
The Astronomical Journal, 2009 Interpretation of high-resolution observations of absorption by interstellar clouds of radiation from extragalactic sources should include the effect of the Earth's motion with respect to the source. High-resolution H I absorption profiles that are not heavily blended have been published for eight sources.

Journal of Physical Organic Chemistry, Volume 39, Issue 4, April 2026.New calculations have been applied to the pyrolysis of pyrrole under shock‐tube conditions and to the radical‐radical reaction between allyl and •CN at low temperature and pressure, using the same mechanistic scheme for both. ABSTRACT The pyrolysis of pyrrole has previously been studied in shock‐tube experiments and in jet‐stirred reactors. The results

Anomalous Neutral Hydrogen Column Densities in Local Interstellar Medium Clouds
The Astrophysical JournalAnalysis of high-resolution spectra of the hydrogen and deuterium Ly α lines provides measurements of interstellar neutral hydrogen column densities N (H i ) to 113 stars within 50 pc of the Sun. Plots of N (H i ) versus distance through the LIC, G, Mic,

Atomic and Molecular Gas in the Milky Way. I. Structure Decomposition
The Astrophysical JournalWe present GDCluster, a fully automated algorithm for decomposing a spectral-line data cube of interstellar gas into coherent structures. Assuming a multi-Gaussian nature of observed spectra, GDCluster employs and augments the derivative spectroscopy ...

Hierarchical structure of the interstellar molecular clouds and star formation
Open Astronomy, 2017 Properties of the hierarchical structures of interstellar molecular clouds are discussed. Particular attention is paid to the statistical correlations between velocity dispersion and size, and between the magnetic field strength and gas density.
