The presence of amino acids in comets and meteorites has long suggested that prebiotic molecules may have formed in space and contributed to the origins of life on Earth.

Broadband Infrared Spectroscopy Of Methanol Isotopologues In pure, H2O-rich, And CO-rich Ice Analogues
Deuterium fractionation is highly efficient during the early stages of star formation, particularly in starless and prestellar cores where temperatures are low (<10 K) and molecular freeze-out onto dust grains […]
Isotopomer-Specific Carbon Isotope Ratio of Complex Organic Molecules in Star-Forming Cores
Recent high-resolution and sensitivity ALMA observations have unveiled the carbon isotope ratios (12C/13C) of Complex Organic Molecules (COMs) in a low-mass protostellar source.
Nascent Chemical Complexity In Prestellar Core IRAS 16293E: Complex Organics And Deuterated Methanol
Prestellar cores represent early sites of low-mass (M ≤ few M⊙) star and planet formation and provide insight into initial chemical conditions of complex organic molecules (COMs).
Correlation Between Formaldehyde and Methanol in Prestellar Cores
Formaldehyde is a key precursor in the formation routes of many complex organic molecules (COMs) in space. It is also an intermediate step in CO hydrogenation sequence that leads to […]
Cosmic-ray Induced Sputtering Of Interstellar Formaldehyde Ices
H2CO is a ubiquitous molecule in the ISM and in the gas phase of prestellar cores, and is likely present in ice mantles, but its main desorption mechanism is unknown. […]
Survey of Complex Organic Molecules in Starless and Prestellar Cores in the Perseus Molecular Cloud
Cold (∼10 K) and dense (∼105 cm−3) cores of gas and dust within molecular clouds, known as starless and dynamically evolved prestellar cores, are the birthplaces of low-mass (M ≤ […]
Rotational Spectroscopy of CH3OD with a Reanalysis of CH3OD Toward IRAS 16293−2422
We have started a measurement campaign of numerous methanol isotopologs in low-lying torsional states in order to provide extensive line lists for radio astronomical observations from an adequate spectroscopic model […]
Carbon Isotope Fractionation of Complex Organic Molecules in Star-Forming Cores
Recent high-resolution and sensitivity ALMA observations have unveiled the carbon isotope ratios (12C/13C) of Complex Organic Molecules (COMs) in a low-mass protostellar source. To understand the 12C/13C ratios of COMs, […]
Enhanced Formation Of Interstellar Complex Organic Molecules On Carbon Monoxide Ice
We investigate the role of carbon monoxide ice in the chemical evolution of prestellar cores using astrochemical rate equation models.
