A unified model for galactic discs: star formation, turbulence driving, and mass transport [PDF]
, 2017 We introduce a new model for the structure and evolution of the gas in galactic discs. In the model the gas is in vertical pressure and energy balance. Star formation feedback injects energy and momentum, and non-axisymmetric torques prevent the gas from

Starbursts in and out of the star-formation main sequence [PDF]
Astronomy & Astrophysics, 2017 Aims. We use high-resolution continuum images obtained with the Atacama Large Millimeter Array (ALMA) to probe the surface density of star formation in z ~ 2 galaxies and study the different physical properties between galaxies within and above the star ...

Early-forming Massive Stars Suppress Star Formation and Hierarchical Cluster Assembly
The Astrophysical Journal, 2023 Feedback from massive stars plays an important role in the formation of star clusters. Whether a very massive star is born early or late in the cluster formation timeline has profound implications for the star cluster formation and assembly processes. We

Runaway stars masquerading as star formation in galactic outskirts [PDF]
MNRAS, 502, L29 (2021), 2020 In the outskirts of nearby spiral galaxies, star formation is observed in extremely low gas surface densities. Star formation in these regions, where the interstellar medium is dominated by diffuse atomic hydrogen, is difficult to explain with classic star formation theories.

Star formation rates and efficiencies in the Galactic Centre [PDF]
, 2017 The inner few hundred parsecs of the Milky Way harbours gas densities, pressures, velocity dispersions, an interstellar radiation field and a cosmic ray ionisation rate orders of magnitude higher than the disc; akin to the environment found in star ...

Star formation inside a galactic outflow [PDF]
Nature, 2017 Recent observations have revealed massive galactic molecular outflows that may have the physical conditions (high gas densities) required to form stars. Indeed, several recent models predict that such massive outflows may ignite star formation within the

The Constant Average Relationship between Dust-obscured Star Formation and Stellar Mass from z = 0 to z = 2.5 [PDF]
, 2017 The total star formation budget of galaxies consists of the sum of the unobscured star formation, as observed in the rest-frame ultraviolet (UV), together with the obscured component that is absorbed and re-radiated by dust grains in the infrared.
