A Temperature or FUV Tracer? The HNC/HCN Ratio in M83 on the GMC Scale
The HNC/HCN ratio is observationally known as a thermometer in Galactic interstellar molecular clouds. A recent study has alternatively suggested that the HNC/HCN ratio is affected by the ultraviolet (UV) […]

Early Planet Formation in Embedded Disks (eDisk) XV: Influence of Magnetic Field Morphology in Dense Cores on Sizes of Protostellar Disks
The magnetic field of a molecular cloud core may play a role in the formation of circumstellar disks in the core. We present magnetic field morphologies in protostellar cores of […]

Planet Formation Regulated By Galactic-scale Interstellar Turbulence
Planets form from protoplanetary discs of dust and gas that surround stars younger than a few million years. The properties of these discs dictate how planets grow, determining the nature, […]

An ALCHEMI Inspection of Sulphur-bearing Species Towards the Central Molecular Zone of NGC 253
Sulphur-bearing species are detected in various environments within Galactic star-forming regions and are particularly abundant in the gas phase of outflows and shocks, and photo-dissociation regions.

Formation of N-bearing Complex Organic Molecules in Molecular Clouds: Ketenimine, Acetonitrile, Acetaldimine, and Vinylamine via the UV Photolysis of C2H2 Ice
The solid-state C2H2 chemistry in interstellar H2O-rich ice has been proposed to explain astronomically observed complex organic molecules (COMs), including ketene (CH2CO), acetaldehyde (CH3CHO), and ethanol (CH3CH2OH), toward early star-forming […]

Laboratory And Astronomical Discovery Of Cyanothioketene, NCCHCS, In The Cold Starless Core TMC-1
We present the detection of cyanothioketene, NCCHCS, in the laboratory and toward TMC-1. This transient species was produced through a discharge of a gas mixture of CH2CHCN and CS2 using […]
