Green Bank Telescope Detection of New Interstellar Aldehydes: Propenal and Propanal (2004, background): “The combination of the prevalence of interstellar aldehydes and the likelihood of subsequent hydrogen addition reactions with aldehydes prompted a successful search for interstellar ethylene glycol (HOCH2CH2OH) by Hollis et al. (2002).”
2018 Census of Interstellar, Circumstellar, Extragalactic, Protoplanetary Disk, and Exoplanetary Molecules (2018, methodology): “HO(CH2)2OH (ethylene glycol) The detection of the g′Ga conformer of HO(CH2)2OH was reported by Hollis et al. (2002) in NRAO 12-m observations of Sgr B2.”
DETECTION OF THE SIMPLEST SUGAR, GLYCOLALDEHYDE, IN A SOLAR-TYPE PROTOSTAR WITH ALMA (2012, background): “This is comparable to the estimates by Hollis et al. (2002) for SgrB2(N), but notably smaller than the inferred values from comet Hale-Bopp where ethylene glycol is at least five times more abundant than glycolaldehyde (Crovisier et al. 2004).”
The Galactic Center: The Largest Oxygen-bearing Organic Molecule Repository (2007, background): “…COMs like the aldehydes propynal (HC2CHO), propenal (CH2CHCHO), propanal (CH3CH2CHO), and glycolaldehyde (CH2OHCHO) and complex alcohols like ethylene glycol (HOCH2CH2OH) have been detected toward one star-forming region in the CMZ, Sgr B2N (Dickens et al. 2001; Hollis et al. 2000, 2002, 2004b).”
Formation of ethylene glycol and other complex organic molecules in star-forming regions (2016, background): “…where saturated species, such as EG, are always more abundant than unsaturated species, such as GA (see Table 7); and in star-forming regions (e.g. Ikeda et al. 2001, Hollis et al. 2002, Bisschop et al. 2007) Therefore, there is evidence that chemistry favors saturated versus unsaturated species.”
Experimental evidence for glycolaldehyde and ethylene glycol formation by surface hydrogenation of CO molecules under dense molecular cloud conditions (2015, background): “Glycerine is a triol and has not been detected in space so far, but ethylene glycol (H2C(OH)CH2OH), a diol, has been observed towards the Galactic Centre source SgrB2(N) (Hollis et al. 2002) as well as around the low-mass Class 0 protostar NGC 1333–IRAS2A (Maury et al. 2014).”
Erratum: Detection of amino acetonitrile in Sgr B2(N) (2008, background): “Recent identifications of “new” species include glycolaldehyde CH2OHCHO (Hollis et al. 2000, 2001), ethylene glycol HOCH2CH2OH (Hollis et al. 2002), and vinyl alcohol CH2CHOH (Turner & Apponi 2001).”
Complex Chemistry in Star-forming Regions: An Expanded Gas-Grain Warm-up Chemical Model (2008, background): “…the richest molecular inventory observed to date (e.g. Nummelin et al. 2000), showing spectral signatures of many additional complex organics, including acetone (CH3COCH3, Snyder et al. 2002), ethylene glycol [(CH2OH)2, Hollis et al. 2002], and glycolaldehyde [CH2(OH)CHO, Hollis et al. 2004].”
Complex organic molecules in the interstellar medium: IRAM 30 m line survey of Sagittarius B2(N) and (M) (2013, background): “A comparison of our 30 m spectrum around 93.0 GHz to the NRAO 12 m spectrum of Hollis et al. (2002) suggests that the emission of ethylene glycol and glycolaldehyde are in the same proportion more extended than the emission of ethyl cyanide.”
