Although first considered as too diluted for the formation of molecules in-situ and too harsh
an environment for their survival, the interstellar medium has turned out to host a rich palette …

We report the detection, for the first time in space, of a new non-functionalised hydrocarbon
cycle in the direction of TMC-1: oC 6 H 4 (ortho-benzyne). We derive a column density for …

To date, 241 individual molecular species, composed of 19 different elements, have been
detected in the interstellar and circumstellar medium by astronomical observations. These …

A family of unidentified infrared emission (UIE) bands has been observed throughout the
Universe. The current observed spectral properties of the UIE bands are summarized. These …

After decades of searching, astronomers have recently identified specific Polycyclic Aromatic
Hydrocarbons (PAHs) in space. Remarkably, the observed abundance of cyanonaphthalene …

We have conducted an extensive search for nitrogen-, oxygen-, and sulfur-bearing
heterocycles toward Taurus Molecular Cloud 1 (TMC-1) using the deep, broadband …

We report the detection of large hydrocarbon cycles toward several cold dense clouds. We
observed four sources (L1495B, Lupus-1A, L483, and L1527) in the Q band (31− 50 GHz) …

Context. Detailed astrochemical models are a key component to interpret the observations of
interstellar and circumstellar molecules since they allow important physical properties of the …

Reactive open-shell species, such as radicals and biradicals, are key intermediates in the
formation of (poly) cyclic hydrocarbon species in a variety of interstellar environments …

Aims. We investigate the outcome of an electrical discharge of naphthalene and search for
the resulting products in the Taurus Molecular Cloud (TMC-1). Methods. Using chirped pulse …
