The Initial Mass Function of Stars: Evidence for Uniformity in Variable Systems [PDF]

open access: yesScience, 2002
The distribution of stellar masses that form in one star formation event in a given volume of space is called the initial mass function (IMF). The IMF has been estimated from low-mass brown dwarfs to very massive stars.

The Arches Cluster Mass Function [PDF]

open access: yesThe Astrophysical Journal, 2006
We have analyzed H and K_s-band images of the Arches cluster obtained using the NIRC2 instrument on Keck with the laser guide star adaptive optics (LGS AO) system. With the help of the LGS AO system, we were able to obtain the deepest ever photometry for this cluster and its neighborhood, and derive the background-subtracted present-day mass function ...

Effects of steady state free precession parameters on cardiac mass, function, and volumes. [PDF]

open access: yes, 2007
PURPOSE: We aimed to investigate comparability of LV volumes, function, and mass acquired with three steady-state free precession (SSFP) pulse sequences, simulating typical vendor and protocol specific differences in data acquisition. METHODS: Twenty-one

The COSMOS2015 galaxy stellar mass function . Thirteen billion years of stellar mass assembly in ten snapshots [PDF]

open access: yes, 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/

The role of molecular filaments in the origin of the prestellar core mass function and stellar initial mass function [PDF]

open access: yesAstronomy & 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

Functional genomics by mass spectrometry [PDF]

open access: yesFEBS Letters, 2000
Systematic analysis of the function of genes can take place at the oligonucleotide or protein level. The latter has the advantage of being closest to function, since it is proteins that perform most of the reactions necessary for the cell. For most protein based (‘proteomic’) approaches to gene function, mass spectrometry is the method of choice.

The Dawes Review 8: Measuring the Stellar Initial Mass Function [PDF]

open access: yesPublications 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.
