The Calibration of Polycyclic Aromatic Hydrocarbon Dust Emission as a Star Formation Rate Indicator in the AKARI NEP Survey
Polycyclic aromatic hydrocarbon (PAH) dust emission has been proposed as an effective extinction-independent star formation rate (SFR) indicator in the mid-infrared (MIR), but this may depend on conditions in the […]

Chemical Models of Interstellar Glycine and Adenine Precursor Aminoacetonitrile (NH2CH2CN)
Aminoacetonitrile (AAN), also known as glycinenitrile, has been suggested as a possible precursor of glycine and adenine in the interstellar medium. Here we present the chemical modeling of AAN and […]

Observations Of Low-mass Protostellar Systems Show Evidence Of Rich Complex Organic Chemistry.
Observations of low-mass protostellar systems show evidence of rich complex organic chemistry. Their low luminosity, however, makes determining abundance distributions of complex organic molecules (COMs) within the water snowline challenging.

The Rich Interstellar Reservoir Of Dinitriles: Detection of Malononitrile and Maleonitrile in TMC-1
While the nitrile group is by far the most prevalent one among interstellar molecules, the existence of interstellar dinitriles (molecules containing two -CN groups) has recently been proven. Here we […]

Formation Of Carbonyl Sulfide (OCS) via SH Radicals In Interstellar CO-rich Ice Under Dense Cloud Conditions
Carbonyl sulfide (OCS) is widely observed in the gas phase towards star-forming regions and was the first of the only two sulfur-bearing species detected in interstellar ices so far. However, […]
