Analytical Characterization Approaches to Measure Prebiotically Relevant Compounds in High Salinity Impact-Induced Hydrothermal Systems

by Keith CowingMay 17, 2026May 17, 2026

Experiments exploring potential emergence-of-life chemistry in a laboratory setting critically depend on simulating realistic early-Earth environments. Such experimental conditions include the implementation of controlled high temperatures and pressures, anoxic gas […]

Integrated intensity maps of representative CH3COCH3 unblended lines observed towards I16272-4837C1. The color scale is the continuum at a wavelength of 3 mm. The white contours indicate CH3COCH3 at difference upper energies. The contour levels are at the 3, 5, 8, 12, 18, 28𝜎. Beam size is shown in the bottom left-hand corner. -- astro-ph.GA

LMA Observations Of Acetone In Hot Cores

by Keith CowingApril 24, 2026April 24, 2026

Acetone (CH3COCH3) is a ubiquitous interstellar molecule, and serves as an important tracer of hot core chemistry. We conducted a line survey of acetone and its precursor acetaldehyde (CH3CHO) towards […]

Graphical Abstract: γ-Ray is capable of driving an aqueous-phase CH4+H2O+O2 conversion selectively into CH3COOH via ⋅CH3 and ⋅OH radical intermediates, and driving an aqueous-phase CH3COOH+NH3 conversion into NH2CH2COOH via ⋅CH2COOH and ⋅NH2 radical intermediates. Such γ-ray driven aqueous-phase methane conversions probably play an important role in the formation network of complex organic molecules in the universe, and provides a strategy to convert abundant CH4 into value-added products at mild conditions. -- Angewandte Chemie International Edition

Detection of Ethanol, Acetone, and Propanal in TMC-1: New O-bearing Complex Organics in Cold Sources

by Keith CowingMarch 28, 2023March 28, 2023

We present the detection of ethanol (C2H5OH), acetone (CH3COCH3), and propanal (C2H5CHO) toward the cyanopolyyne peak of TMC-1. These three O-bearing complex organic molecules are known to be present in […]
