Water formation by reaction of H2 and O on silicate surfaces as a first step towards generation of interstellar ice mantles is possible thanks to the activation of H2 due to interacting with Fe2+ ions and accelerated by quantum tunnelling effects

Sulphur depletion is a long-standing problem in the astrochemical community and computational studies can help in discovering the behaviour of S-bearing species. The first step is understanding what happens to gas phase species when they adsorb on the grains, a phenomenon described by the binding energies.

This is a combined experimental and computational work focused on measuring and calculating binding energies of acetaldehyde, clarify how to reconcile theoretical BEs and experimental TPD data and finally to give astrochemical implications based on the previous points.

Theoretical calculations shed light on the adsorption of some of the most common interstellar complex organic molecules on a crystalline water ice surface, underlining the contribution of dispersive forces in accurately describing the interactions in the adsorbate/ice systems.

The formation of interstellar complex organic molecules (iCOMs) has bee investigated adoting radical-radical coupling reactions on amorphous water ice, finding that many of these reactions do have an energy barrier due to the interaction of the radicals with the water ice surfac, and that there are competitive channels involving the abstraction of an H atom from one radical to the other.

We have analyzed the superbolides recorded by the US Government satellite sensors. We found that ∼1/4 of the large fireballs detected from the space could be associated with near-Earth objects or meteoroid streams. The suspected interstellar rocky messenger exhibits a remarkably high tensile strength, indicating that only large or strong enough objects may survive the harsh interstellar medium.

Theoretical investigation of the reaction between the radical CCH and the icy surface of dust grains, leading to the formation of ethanol without the need of an external energy input.

A detailed review that focuses on computational works dealing with the formation of glycine in the interstellar medium, its transportation to the early Earth, and its conversion into peptides under prebiotic conditions.

A detailed review dealing with binding energies and how to obtain them through thermal desorption techniques and quantum mechanical simulations for astrochemical purposes.

The interaction of water, from one molecule to different coverages, on the most stable (110) surface of schreibersite (Fe2NiP), alongside different physico-chemcial properties of the interface, has been simulated computationally.
