Interstellar gas, dust and diffuse bands in the SMC
Aims. In order to gain new insight into the unidentified identity of the diffuse interstellar band (DIB) carriers, this paper describes research into possible links between the shape of theExpand
The Large Magellanic Cloud: diffuse interstellar bands, atomic lines and the local environmental conditions
The Large Magellanic Cloud (LMC) offers a unique laboratory to study the diffuse interstellar bands (DIBs) under conditions that are profoundly different from those in the Galaxy. DIB carrierExpand
Hydrocarbon Anions in Interstellar Clouds and Circumstellar Envelopes
The recent detection of the hydrocarbon anion C6H- in the interstellar medium has led us to investigate the synthesis of hydrocarbon anions in a variety of interstellar and circumstellarExpand
Detection of C8H– and Comparison with C8H toward IRC +10 216
We report the detection of new transitions of octatetraynyl (C8H) toward the circumstellar envelope IRC +10 216 using data taken with the 100 m Green Bank Telescope (GBT). In addition, we report fiveExpand
ETHYL CYANIDE ON TITAN: SPECTROSCOPIC DETECTION AND MAPPING USING ALMA
We report the first spectroscopic detection of ethyl cyanide (C2H5CN) in Titan’s atmosphere, obtained using spectrally and spatially resolved observations of multiple emission lines with the AtacamaExpand
ISOTOPIC ANOMALIES IN PRIMITIVE SOLAR SYSTEM MATTER: SPIN-STATE-DEPENDENT FRACTIONATION OF NITROGEN AND DEUTERIUM IN INTERSTELLAR CLOUDS
Organic material found in meteorites and interplanetary dust particles is enriched in D and 15N. This is consistent with the idea that the functional groups carrying these isotopic anomalies,Expand
Multi-epoch high-resolution spectroscopy of SN 2011fe - Linking the progenitor to its environment
Context. The nearby Type Ia SN 2011fe has provided an unprecedented opportunity to derive some of the properties of the progenitor system, which is one of the key open problems in the supernova (SN)Expand
The abundance of C3H2 and other small hydrocarbons in the diffuse interstellar medium
Hydrocarbons are ubiquitous in the interstellar medium, observed in diverse environments ranging from diffuse to molecular dark clouds and strong photon-dominated regions near HII regions. Recently,Expand
Formation of benzene in the interstellar medium
TLDR
It is demonstrated in crossed molecular beam experiments combined with electronic structure and statistical calculations that benzene (C6H6) can be synthesized via the barrierless, exoergic reaction of the ethynyl radical and 1,3-butadiene, under single collision conditions. Expand
Discovery of Interstellar Anions in Cepheus and Auriga
We report the detection of microwave emission lines from the hydrocarbon anion C6H– and its parent neutral C6H in the star-forming region L1251A (in Cepheus), and the pre-stellar core L1512 (inExpand
