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 …

This review examines the state-of-the-art knowledge of high-mass star and massive cluster
formation, gained from ambitious observational surveys, which acknowledges the multiscale …

We present PHANGS–ALMA, the first survey to map CO J= 2→ 1 line emission at∼ 1''∼ 100
pc spatial resolution from a representative sample of 90 nearby (d≲ 20 Mpc) galaxies that lie …

The region around the Galactic Center (GC) is now well established to be brighter at
energies of a few GeV than what is expected from conventional models of diffuse gamma …

One of the key open questions in extragalactic astronomy is what stops star formation in
galaxies. While it is clear that the cold gas reservoir, which fuels the formation of new stars …

We identify stellar structures in the PHANGS sample of 74 nearby galaxies and construct
morphological masks of sub-galactic environments based on Spitzer 3.6 μm images. At the …

We present and discuss the results of the Herschel Gould Belt survey (HGBS) observations
in an~ 11 deg 2 area of the Aquila molecular cloud complex at d~ 260 pc, imaged with the …

We present a new derivation of the Milky Way's current star formation rate (SFR) based on
the data of the Herschel InfraRed Galactic Plane Survey (Hi-GAL). We estimate the …

Galactic outflows are ubiquitous in galaxies containing active star formation or supermassive
black hole activity. The presence of a large-scale outflow from the center of our own Galaxy …

Star formation is a fundamental process for galactic evolution. One issue over the last
several decades has been determining whether star formation is induced by external …
