Dust grains absorb half of the radiation emitted by stars throughout the history of the
universe, re-emitting this energy at infrared wavelengths,–. Polycyclic aromatic …

We present a new model of interstellar dust in which large grains are a single composite
material," astrodust," and nanoparticle-sized grains come in distinct varieties including …

A family of unidentified infrared emission (UIE) bands has been observed throughout the
Universe. The current observed spectral properties of the UIE bands are summarized. These …

Polycyclic aromatic hydrocarbons (PAHs) play a critical role in the reprocessing of stellar
radiation and balancing the heating and cooling processes in the interstellar medium but …

The PHANGS collaboration has been building a reference data set for the multiscale,
multiphase study of star formation and the interstellar medium (ISM) in nearby galaxies. With …

We present maps of the 3.3 μm polycyclic aromatic hydrocarbon (PAH) emission feature in
NGC 628, NGC 1365, and NGC 7496 as observed with the Near-Infrared Camera imager on …

Aims. This paper utilises the James Webb Space Telescope (JWST) Mid-Infrared Instrument
(MIRI) to extend the observational studies of dust and polycyclic aromatic hydrocarbon …

We present maps tracing the fraction of dust in the form of polycyclic aromatic hydrocarbons
(PAHs) in IC 5332, NGC 628, NGC 1365, and NGC 7496 from JWST/MIRI observations. We …

Ratios of polycyclic aromatic hydrocarbon (PAH) vibrational bands are a promising tool for
measuring the properties of the PAH population and their effect on star formation. The …

We demonstrate that the inference of galaxy stellar masses via spectral energy distribution
(SED) fitting techniques for galaxies formed in the first billion years after the Big Bang carries …
