Detection of two interstellar polycyclic aromatic hydrocarbons via spectral matched filtering [PDF]
Science, 2021 Identifying PAHs in space Midinfrared spectroscopy has shown that polycyclic aromatic hydrocarbons (PAHs) are abundant in many astronomical objects, but this technique cannot determine which specific PAH molecules are present.

The census of interstellar complex organic molecules in the Class I hot corino of SVS13-A [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We present the first census of the interstellar Complex Organic Molecules (iCOMs) in the low-mass Class I protostar SVS13-A, obtained by analysing data from the IRAM-30m Large Project ASAI (Astrochemical Surveys At IRAM).

The formation of peptide-like molecules on interstellar dust grains [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Molecules with an amide functional group resemble peptide bonds, the molecular bridges that connect amino acids, and may thus be relevant in processes that lead to the formation of life.

Molecular Hydrogen and its Proxies HCO+ and CO in the Diffuse Interstellar Medium
The Astrophysical Journal, 2023 There is a robust polyatomic chemistry in diffuse, partially molecular interstellar gas that is readily accessible in absorption at radio/millimeter/submillimeter wavelengths.

On the Spatial Distribution of 13CO Structures within 12CO Molecular Clouds
The Astrophysical Journal, 2023 We look into the 2851 ^12 CO molecular clouds harboring ^13 CO structures to reveal the distribution of the projected angular separations and radial velocity separations between their internal ^13 CO structures.

Gas-phase Chemistry in the Interstellar Medium: The Role of Laboratory Astrochemistry
Frontiers in Astronomy and Space Sciences, 2022 “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.
