Neutral and Ionized Hydrides in Star-forming Regions -- Observations with Herschel/HIFI [PDF]
, 2013 The cosmic abundance of hydrides depends critically on high-energy UV, X-ray, and particle irradiation. Here we study hydrides in star-forming regions where irradiation by the young stellar object can be substantial, and density and temperature can be ...

Cretaceous-Tertiary boundary deposits in Denmark: A diachroneity [PDF]
Journal of the Serbian Chemical Society, 2004 The lateral distribution of predominantly terrestrial kerogen or humics enriched with copper(II) porphyrins (Cu-P) across the Danish marine basin implies that the alleged Cretaceous-Tertiary (KT) boundary deposits in western Denmark (at the Nye Kløv ...

Ionize Hard: Interstellar PO+ Detection
Frontiers in Astronomy and Space Sciences, 2022 We report the first detection of the phosphorus monoxide ion (PO+) in the interstellar medium. Our unbiased and very sensitive spectral survey toward the G+0.693–0.027 molecular cloud covers four different rotational transitions of this molecule, two of ...
