The stellar initial mass function [PDF]

open access: bronzeProceedings of the International Astronomical Union, 2006
Abstract The IMF UNIVERSALITY HYPOTHESIS cannot be discarded despite the existence of the CLUSTER IMF THEOREM. This means that the currently existing star-formation theory fails to describe the stellar outcome. The IGIMF THEOREM, however, predicts a variation of galaxy-wide IMFs in dependence of the galaxy's star-formation rate even if the IMF ...

Variation in the stellar mass function along stellar streams [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
ABSTRACT Stellar streams are the inevitable end product of star cluster evolution, with the properties of a given stream being related to its progenitor. We consider how the dynamical history of a progenitor cluster, as traced by the evolution of its stellar mass function, is reflected in the resultant stream.

The COSMOS2015 galaxy stellar mass function [PDF]

open access: yesAstronomy & Astrophysics, 2017
We measure the stellar mass function (SMF) and stellar mass density of galaxies in the COSMOS field up to z ~ 6. We select them in the near-IR bands of the COSMOS2015 catalogue, which includes ultra-deep photometry from UltraVISTA-DR2, SPLASH, and Subaru/Hyper Suprime-Cam. At z> 2.5 we use new precise photometric redshifts with error σz = 0.03(1 + z)

The stellar mass function and star formation rate-stellar mass relation of galaxies at z ~ 4 - 7 [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
We investigate the evolution of the star formation rate-stellar mass relation (SFR-M*) and Galaxy Stellar Mass Function (GSMF) of z ~ 4-7 galaxies, using cosmological simulations run with the smoothed particle hydrodynamics code P-GADGET3(XXL).

EVIDENCE FOR TWO DISTINCT STELLAR INITIAL MASS FUNCTIONS [PDF]

open access: yesThe Astrophysical Journal, 2012
We present velocity dispersion measurements of 20 Local Group stellar clusters (7 < log(age [yrs]) < 10.2) from integrated light spectra and examine the evolution of the stellar mass-to-light ratio, Upsilon_*. We find that the clusters deviate from the evolutionary tracks corresponding to simple stellar populations drawn from standard stellar ...

Stellar initial mass function varies with metallicity and time

open access: yesNature, 2023
Most structural and evolutionary properties of galaxies strongly rely on the stellar initial mass function (IMF), namely the distribution of the stellar mass formed in each episode of star formation. As the IMF shapes the stellar population in all stellar systems, it turns out to become one of the most fundamental concepts of modern astronomy.
