Highly unsaturated carbon chains, including polyynes, have been detected in many astronomical regions and planetary systems.
Life on Earth uses DNA as the central template for self-replication, genetic encoding, and information transfer.
The discovery of pyrene derivatives in a distant interstellar cloud may help to reveal how our own solar system formed.
Polycyclic aromatic hydrocarbons (PAHs) are thought to be the most abundant class of molecules in space, yet their interstellar lifecycle is poorly understood due to difficulties detecting individual PAHs.
Polycyclic aromatic hydrocarbons (PAHs) are among the most ubiquitous compounds in the universe, accounting for up to ~25% of all interstellar carbon. Since most unsubstituted PAHs do not possess permanent […]
We used new high spectral resolution observations of propynal (HCCCHO) towards TMC-1 and in the laboratory to update the spectral line catalog available for transitions of HCCCHO – specifically at […]
We have conducted Q-band (30 GHz − 50 GHz) line survey observations toward a carbon-chain emission peak in the Serpens South cluster-forming region with the extended Q-band (eQ) receiver installed […]
While the nitrile group is by far the most prevalent one among interstellar molecules, the existence of interstellar dinitriles (molecules containing two -CN groups) has recently been proven. Here we […]
We report the first identification in space of HC3N+, the simplest member of the family of cyanopolyyne cations. Three rotational transitions with half-integer quantum numbers from J=7/2 to 11/2 have […]
Aromatic molecules represent fundamental building blocks in prebiotic chemistry and are contemplated as vital precursors to DNA and RNA nitrogen bases.
