The characteristic mass that sets the peak of the stellar initial mass function (IMF) is closely
linked to the thermodynamic behaviour of interstellar gas, which controls how gas fragments …

The stellar initial mass function (IMF) is commonly assumed to be an invariant probability
density distribution function of initial stellar masses. These initial stellar masses are …

We derive the low-redshift galaxy stellar mass function (GSMF), inclusive of dust corrections,
for the equatorial Galaxy And Mass Assembly (GAMA) data set covering 180 deg2. We …

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 …

Variations in the stellar initial mass function (IMF) have been invoked to explain the
spectroscopic and dynamical properties of early-type galaxies (ETGs). However, no …

The initial mass function (IMF), describing the distribution of birth masses of stars, plays a
pivotal role in establishing the observable properties of galaxies. This article reviews the …

ABSTRACT Based on Multi-Unit Spectroscopic Explorer (MUSE) integral-field data we
present evidence for a radial variation at the low-mass end of the stellar initial-mass function …

We confirm two new local massive relic galaxies, ie untouched survivors of the early
Universe massive population: Mrk 1216 and PGC 032873. Both show early and peaked …

At present, the main challenge to the interpretation of variations in gravity-sensitive line
strengths as driven by a non-universal initial mass function (IMF) lies in understanding the …

Using new long-slit spectroscopy obtained with X-Shooter at ESO-VLT, we study, for the first
time, radial gradients of optical and near-infrared initial mass function (IMF)-sensitive …
