International Journal of Chemical Kinetics, EarlyView.ABSTRACT In the interstellar medium, chemical reactions proceed under conditions vastly different to those on Earth; these include extremely low temperatures and densities and take place in the gas phase and on water–ice grains. Understanding the energetics and more importantly the kinetics of such reactions is of relevance to the consequences on how ...

Kinematics of a high-redshift galaxy: A case study [PDF]
Serbian Astronomical Journal, 2000 A kinematics of a z = 2.81 galaxy toward bright QSO 0528-250, as inferred from the absorption spectroscopy is discussed. There are sufficient arguments for a far-reaching conclusion that we are observing an older, uninvolved version of the local Galactic

Journal of Field Robotics, EarlyView.ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

The Astrophysical JournalThe chemistry within the interstellar medium (ISM) is notably influenced by the interplay between kinetics and photochemical processes, which play significant roles in both the formation and destruction of molecular species.

A Nest of Diffuse Interstellar Bands—Likely of Common Origin
The Astronomical JournalDiffuse interstellar bands (DIBs) have been proposed to cluster into distinct “families” each potentially linked to a single carrier molecule. In our study, we focus on identifying such a family within the spectral range of approximately 4945–4990 Å ...

FAST Discovery of a Fast Neutral Hydrogen Outflow
The Astrophysical Journal Letters, 2023 In this letter, we report the discovery of a fast neutral hydrogen outflow in SDSS J145239.38+062738.0, a merging radio galaxy containing an optical type I active galactic nucleus (AGN).

International Journal of Chemical Kinetics, Volume 58, Issue 6, Page 269-277, June 2026.ABSTRACT In the past two decades numerous experiments have been conducted on the kinetics of reactions occurring at low temperatures on inert matrices. In particular, unimolecular proton‐transfer photo‐reactions of compounds containing a carbon–sulfur double bond, or thione group C═S, can lead to the formation of higher energy isomers or tautomers with

Shaken or Stirred: The Diffuse Interstellar Medium with Exceptionally High SiO Abundance
The Astrophysical Journal, 2023 Interstellar shocks, a key element of stellar feedback processes, shape the structure of the interstellar medium (ISM) and are essential for the chemistry, thermodynamics, and kinematics of interstellar gas.
