Complex organic molecules and cosmic ray ionisation rate towards the massive protostar Cepheus A HW2
Emma W. Nielsen, Anna Punanova, Eva Wirström +5
Cosmic rays (CRs) are important drivers for molecular chemistry in star-forming regions, and laboratory experiments have shown that CRs can stimulate the release of complex organic…
Deep Search for Glycine Conformers in Barnard 5
Tadeus Carl, Eva Wirström, Per Bergman +3
One of the most fundamental hypotheses in astrochemistry and astrobiology states that crucial biotic molecules like glycine (NHCHCOOH) found in meteorites and comets are in…
Emission from HCN and CHOH in comets. Onsala 20-m observations and radiative transfer modelling
P. Bergman, M. S. Lerner, A. O. H. Olofsson +5
The aim of this work is to characterize HCN and CHOH emission from recent comets. We used the Onsala 20-m telescope to search for millimetre transitions of HCN towards a sample…
Chemical complexity induced by efficient ice evaporation in the Barnard 5 molecular cloud
Vianney Taquet, Eva Wirström, Steven B. Charnley +3
Cold gas-phase water has recently been detected in a cold dark cloud, Barnard 5 located in the Perseus complex, by targeting methanol peaks as signposts for ice mantle evaporation.…
Ground-state ammonia and water in absorption towards Sgr B2
E. S. Wirström, P. Bergman, J. H. Black +8
We have used the Odin submillimetre-wave satellite telescope to observe the ground state transitions of ortho-ammonia and ortho-water, including their 15N, 18O, and 17O isotopologu…
