Observations that resolve nearby galaxies into individual regions across multiple phases of
the gas–star formation feedback “matter cycle” have provided a sharp new view of molecular …

We present the PHANGS-MUSE survey, a programme that uses the MUSE integral field
spectrograph at the ESO VLT to map 19 massive (9.4< log (M⋆/M⊙)< 11.0) nearby (D≲ 20 …

The processes of star formation and feedback, regulating the cycle of matter between gas
and stars on the scales of giant molecular clouds (GMCs;∼ 100 pc), play a major role in …

Ionized nebulae provide critical insights into the conditions of the interstellar medium (ISM).
Their bright emission lines enable the measurement of physical properties, such as the gas …

The first JWST observations of nearby galaxies have unveiled a rich population of bubbles
that trace the stellar-feedback mechanisms responsible for their creation. Studying 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 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 …

The CO-to-H 2 conversion factor (α CO) is central to measuring the amount and properties of
molecular gas. It is known to vary with environmental conditions, and previous studies have …
