The role of molecular filaments in the origin of the prestellar core mass function and stellar initial mass function [PDF]
Astronomy & Astrophysics, 2019 Context. The origin of the stellar initial mass function (IMF) is one of the most debated issues in astrophysics. Aims. Here we explore the possible link between the quasi-universal filamentary structure of star-forming molecular clouds and the origin of

Fragmentation and the initial mass function [PDF]
International Astronomical Union Colloquium, 1989 A central problem in the theory of star formation is to understand the spectrum of masses, or Initial Mass Function, with which stars are formed. The fundamental role of the IMF in galactic evolution has been described by Tinsley (1980), and an extensive review of evidence concerning the IMF and its possible variability has been presented by Scalo ...

THE INITIAL MASS FUNCTION OF EARLY-TYPE GALAXIES [PDF]
The Astrophysical Journal, 2010 We determine an absolute calibration of the initial mass function (IMF) of early-type galaxies, by studying a sample of 56 gravitational lenses identified by the SLACS Survey. Under the assumption of standard Navarro, Frenk & White dark matter halos, a combination of lensing, dynamical, and stellar population synthesis models is used to disentangle

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).

The initial mass function of a massive relic galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Massive relic galaxies formed the bulk of their stellar component before z ~ 2 and have remained unaltered since then. Therefore, they represent a unique opportunity to study in great detail the frozen stellar population properties of those galaxies that populated the primitive Universe.

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.

The Initial Mass Function as given by the fragmentation [PDF]
Astronomische Nachrichten, 2005 The dichotomy between a universal mass function (IMF) and a variable IMF which depends on local physical parameters characterises observational and theoretical stellar astronomy. In this contribution the available distributions of probability are briefly reviewed.

The Stellar Initial Mass Function in Early-type Galaxies from Absorption Line Spectroscopy. III. Radial Gradients [PDF]
, 2016 There is good evidence that the centers of massive early-type galaxies have a bottom-heavy stellar initial mass function (IMF) compared to that of the Milky Way.
