The Dawes Review 8: Measuring the Stellar Initial Mass Function [PDF]
Publications Astronomical Society of Australia, 2018 The birth of stars and the formation of galaxies are cornerstones of modern astrophysics. While much is known about how galaxies globally and their stars individually form and evolve, one fundamental property that affects both remains elusive.

The stellar initial mass function of the solar neighbourhood revealed by Gaia [PDF]
Monthly notices of the Royal Astronomical Society, 2019 I use a sample of more than 120 000 stars in the solar neighbourhood, with parallaxes, magnitudes and colours estimated with unprecedented accuracy by the second data release of the Gaia mission, to derive the initial mass function of the Galactic disc.

Simulating star clusters across cosmic time – I. Initial mass function, star formation rates, and efficiencies [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present radiation-magneto-hydrodynamic simulations of star formation in self-gravitating, turbulent molecular clouds, modelling the formation of individual massive stars, including their UV radiation feedback.

The Unusual Initial Mass Function of the Arches Cluster [PDF]
Astrophysical Journal, 2018 As a young massive cluster in the central molecular zone, the Arches cluster is a valuable probe of the stellar initial mass function (IMF) in the extreme Galactic center environment.

On the black hole content and initial mass function of 47 Tuc [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The globular cluster (GC) 47 Tuc has recently been proposed to host an intermediate-mass black hole (IMBH) or a population of stellar mass black holes (BHs).

Initial mass function variations cannot explain the ionizing spectrum of low metallicity starbursts [PDF]
Astronomy & Astrophysics, 2018 Aims. Observations of both galaxies in the distant Universe and local starbursts are showing increasing evidence for very hard ionizing spectra that stellar population synthesis models struggle to reproduce.

The stellar population and initial mass function of NGC 1399 with MUSE [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We present spatially resolved measurements of the stellar initial mass function (IMF) in NGC1399, the largest elliptical galaxy in the Fornax Cluster.

Constraining the Initial Mass Function via Stellar Transients
UniverseThe stellar initial mass function (IMF) represents a fundamental quantity in astrophysics and cosmology describing the mass distribution of stars from low mass all the way up to massive and very massive stars. It is intimately linked to a wide variety of

SDSS-IV MaNGA: Variation of the Stellar Initial Mass Function in Spiral and Early-type Galaxies [PDF]
, 2017 We perform Jeans anisotropic modeling (JAM) on elliptical and spiral galaxies from the MaNGA DR13 sample. By comparing the stellar mass-to-light ratios estimated from stellar population synthesis and from JAM, we find a systematic variation of the ...
