More Sulphur In TMC-1: Discovery Of The NC3S And HC3S Radicals With The QUIJOTE Line Survey
We present the detection of the free radicals NC3S and HC3S towards TMC-1 with the QUIJOTE line survey. The derived column densities are (1.4±0.2)×1011 for NC3S and (1.5±0.2)×1011 for HC3S.

Evidence Of Sulfur Rings In Dark Interstellar Clouds
For the first time, a team of scientists from HFML-FELIX at Radboud University has unveiled the cosmic fingerprints of sulfur rings. These results, published in Nature Communications, may shed new […]

Nitrogen Abundance Distribution in the Inner Milky Way
We combine a new Galactic plane survey of Hydrogen Radio Recombination Lines (RRLs) with far-infrared (FIR) surveys of ionized Nitrogen, N+, to determine Nitrogen abundance across Galactic radius.

Formation of S-bearing Complex Organic Molecules In Interstellar Clouds Via Ice Reactions With C2H2, HS, And Atomic H
The chemical network governing interstellar sulfur has been the topic of unrelenting discussion for the past decades due to the conspicuous discrepancy between its expected and observed abundances in different […]

Replication of Filtered Interferometer Measurements In Interstellar Communications
Interstellar communication signals have been conjectured to be present, albeit difficult to identify. Experiments conducted since 2018 indicate an anomalous presence of a type of speculated interstellar signal, delta-t delta-f […]

Investigation of the Rotational Spectrum of CH317OH and its Tentative Detection Toward Sagittarius B2(N)
Methanol is an abundant molecule in space. The column density of CH138OH is in some star-forming regions so high that the search for CH317OH is promising. But only very few […]

Central Oxygen Abundances In The Spiral Galaxies Of The MaNGA Survey: Galaxies With Central Starbursts
We examine whether there are deviations of the local central oxygen abundances in spiral galaxies from the general metallicity gradients.

Discovery Of The Interstellar Cyanoacetylene Radical Cation HC3N+
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 […]
