• Complex organic molecules in protoplanetary disks (2013, background): “…Vasyunin & Herbst (2013) suggested reactive desorption from grain surfaces followed by radiative associationin the gas phase as a potential mechanism for the production of several complex molecules recently detected in dark clouds and prestellar cores (Bacmann et al. 2012; Cernicharo et al. 2012).”
• THE ORIGIN OF COMPLEX ORGANIC MOLECULES IN PRESTELLAR CORES (2014, background): “Important non-detections include CH3OCH3, HCOOCH3 and CH3O, which were, on the contrary, detected in other prestellar cores (Öberg et al. 2010; Cernicharo et al. 2012; Bacmann et al. 2012).”
• Formation of Complex Molecules in Prestellar Cores: A Multilayer Approach (2017, methodology): “Also, for comparison, abundances of COMs in L1689B and B1-b are shown, taken from Bacmann et al. (2012) and Cernicharo et al. (2012).”
• Formation of complex organic molecules in cold objects: the role of gas-phase reactions (2015, background): “On the contrary, the methoxy abundance measured by Cernicharo et al. (2012) is 5 times lower than the DME and MF abundances, at odds with our predictions.”
• Binding energies: New values and impact on the efficiency of chemical desorption (2017, background): “The observation of complex organic molecules in cold and dense environments of the interstellar medium has increased the interest of the community onto such processes (Bacmann et al. 2012; Cernicharo et al. 2012; Vastel et al. 2014).”
• Gas and grain chemical composition in cold cores as predicted by the Nautilus three-phase model (2016, background): “However, the recent detection of molecules such as methyl formate or dimethyl ether in cold regions (Cernicharo et al. 2012; Bacmann et al. 2012) have challenged models and brought some authors (see Balucani et al. 2015, for example) to reassess the relative contribution of gas phase reactions…”
• Grain Surface Models and Data for Astrochemistry (2017, background): “High sensitivity observations have shown that complex organic molecules are also present in the gas phase in cold environments (∼ 10 K), albeit at a low level with respect to molecular hydrogen (Öberg et al. 2010, 2011; Cernicharo et al. 2012; Bacmann et al. 2012; Vastel et al. 2014).”
• Astrochemistry and compositions of planetary systems (2020, background): “of this initial organic ice reservoir is converted into more complex organics in interstellar clouds (Öberg et al. 2010; Bacmann et al. 2012; Cernicharo et al. 2012; Vastel et al. 2014; Jiménez-Serra et al. 2016; Scibelli and Shirley 2020).”
• REACTIVE DESORPTION AND RADIATIVE ASSOCIATION AS POSSIBLE DRIVERS OF COMPLEX MOLECULE FORMATION IN THE COLD INTERSTELLAR MEDIUM (2013, methodology): “Since the methoxy radical (CH3O) was detected in the cold core B1-b (Cernicharo et al. 2012), we introduced four gas-phase reactions for this species, which is produced during the hydrogenation of CO on grain mantles followed by desorption.”
• 2018 Census of Interstellar, Circumstellar, Extragalactic, Protoplanetary Disk, and Exoplanetary Molecules (2018, methodology): “CH3O (methoxy radical) The detection of CH3O was reported in IRAM 30-m observations of B1-b by Cernicharo et al. (2012).”
• H-atom addition and abstraction reactions in mixed CO, H2CO and CH3OH ices – an extended view on complex organic molecule formation (2016, background): “Typically, non-thermal desorption mechanisms, that is, upon impacting cosmic rays or irradiation by secondary UV photons, are expected to explain the effective transfer from solid state to gas phase (Bacmann et al. 2012; Cernicharo et al. 2012).”
