Spectroscopic FTIR study for pathway of ribose formation via formose reaction in Astrochemistry
Ribose is one of the crucial molecular species in the study of the origin of life as it is the backbone of ribonucleic acid (RNA). On the early Earth, sugars including ribose are thought to be formed through formose reaction.

Astrochemistry: Synthesis and Modelling [PDF]
We discuss models that astrochemists have developed to study the chemical composition of the interstellar medium. These models aim at computing the evolution of the chemical composition of a mixture of gas and dust under as- trophysical conditions. These conditions, as well as the geometry and the physical dynamics, have to be adapted to the objects ...

Gas-phase Chemistry in the Interstellar Medium: The Role of Laboratory Astrochemistry
“Who” and how? In this simple question the complexity of the interstellar chemistry is encapsulated. “Who” refers to what molecules are present in the interstellar medium (ISM) and “how” to the mechanisms that led to their formation.

Electron irradiation and thermal chemistry studies of interstellar and planetary ice analogues at the ICA astrochemistry facility [PDF]
The modelling of molecular excitation and dissociation processes relevant to astrochemistry requires the validation of theories by comparison with data generated from laboratory experimentation.

The Influence of Galactic Cosmic Rays on Ion-Neutral Hydrocarbon Chemistry in the Upper Atmospheres of Free-Floating Exoplanets [PDF]
Cosmic rays may be linked to the formation of volatiles necessary for prebiotic chemistry. We explore the effect of cosmic rays in a hydrogen-dominated atmosphere, as a proof-of-concept that ion-neutral chemistry may be important for modelling hydrogen ...
