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).”
Complex organic molecules in the interstellar medium: IRAM 30 m line survey of Sagittarius B2(N) and (M) (2013, background): “Most complex organic molecules reported so far, such as acetic acid (CH3COOH, Mehringer et al. 1997), glycolaldehyde (CH2(OH)CHO, Hollis et al. 2000), acetamide (CH3CONH2, Hollis et al. 2006), aminoacetonitrile (NH2CH2CN, Belloche et al. 2008), or ethyl formate (C2H5OCHO, Belloche et al. 2009),…”
On the Formation of Glycolaldehyde (HCOCH2OH) and Methyl Formate (HCOOCH3) in Interstellar Ice Analogs (2007, background): “Hollis et al. (2000) detected the presence of glycolaldehydewithin Sgr B2(N)YLMH, and although this is the only source where it has been identified, several subsequent studies have confirmed its presence (Hollis et al. 2001, 2004; Halfen et al. 2006).”
Green Bank Telescope Detection of New Interstellar Aldehydes: Propenal and Propanal (2004, background): “Consistent with this, we (Hollis et al. 2000) successfully detected interstellar glycolaldehyde (CH2OHCHO) and suggested that it might result from the polymerization of two formaldehyde molecules (H2CO) analogous to the early stage of the sugar synthesis (formose) reaction studied in the laboratory…”
Increased complexity in interstellar chemistry: detection and chemical modeling of ethyl formate and n-propyl cyanide in Sagittarius B2(N) (2009, background): “…its rich molecular content: most complex organic molecules such as, e.g., acetic acid (CH3COOH, Mehringer et al. 1997), glycolaldehyde (CH2(OH)CHO, Hollis et al. 2000), acetamide (CH3CONH2, Hollis et al. 2006), and aminoacetonitrile (NH2CH2CN, Belloche et al. 2008a,b), were first discovered in…”
Mechanistical Studies on the Irradiation of Methanol in Extraterrestrial Ices (2007, background): “…and the C2H4O2 group (glycolaldehyde [CH2OHCHO], methyl formate [CH3OCHO], and acetic acid [CH3COOH]); all thesemolecules have now been identified in hot molecular cores (Gottlieb 1973; Brown et al. 1975; Dickens & Irvine 1997; Mehringer et al. 1997; Hollis et al. 2000; Turner & Apponi 2001).”
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, result): “Unlike the results for many other species, this model does not reproduce the low ro- tational temperatures for glycolaldehyde observed by Hollis et al. (2000, 2001, 2004) in Sgr B2(N).”
2018 Census of Interstellar, Circumstellar, Extragalactic, Protoplanetary Disk, and Exoplanetary Molecules (2018, methodology): “CH2OHCHO (glycolaldehyde) The detection of CH2OCHO was reported by Hollis et al. (2000) in NRAO 12-m observations of Sgr B2.”
Complex organic molecules in protoplanetary disks (2013, background): “These species have been detected in the gas phase in the hot core, Sgr B2(N), and in the low-mass protostar, IRAS 16293+2422 (see, e.g., Hollis et al. 2000; Jørgensen et al. 2012).”
Interstellar Antifreeze: Ethylene Glycol (2002, background): “However, Hollis et al. (2000) assumed that glycolaldehyde, like its isomers methyl formate and acetic acid, would be confined to the ∼5 diameter of the LMH core source.”
DETECTION OF THE SIMPLEST SUGAR, GLYCOLALDEHYDE, IN A SOLAR-TYPE PROTOSTAR WITH ALMA (2012, background): “41+0.31 (Beltrán et al. 2009) to the average of 5–6.5 found on more extended scales toward SgrB2(N) (Hollis et al. 2000; Requena-Torres et al. 2008).”
The Gas-Phase Formation of Methyl Formate in Hot Molecular Cores (2004, background): “While methyl formate has been found in numerous sources (Ellder et al. 1980; Millar et al. 1997; Nummelin et al. 2000), acetic acid (Mehringer et al. 1997) and glycolaldehyde (Hollis et al. 2000) have been found only in the Sgr B2(N-LMH) source.”
Water and astrobiology (2007, background): “Using this approach Bennett and Kaiser (2007a, b) and Bennett et al. (2007) determined that (1) a binary model ice of CO/CH3OH leads to the formation of all three C2H4O2 isomers, (2) the binary ice CO2/CH4 may form CH3COOH and HCOOCH3, and (3) two H2CO molecules can form HOCH2CHO and HCOOCH3 (Table ”
