Massive stars reveal variations of the stellar initial mass function in the Milky Way stellar clusters [PDF]
, 2016 We investigate whether the stellar initial mass function (IMF) is universal, or whether it varies significantly among young stellar clusters in the Milky Way. We propose a method to uncover the range of variation of the parameters that describe the shape

Monte-Carlo experiments on star-cluster induced integrated-galaxy IMF variations
, 2004 As most if not all stars are born in stellar clusters the shape of the mass function of the field stars is not only determined by the initial mass function of stars (IMF) but also by the cluster mass function (CMF).

A Universal Stellar Initial Mass Function? A critical look at variations in extreme environments [PDF]
, 2010 Whether the stellar initial mass function (IMF) is universal or is instead sensitive to environmental conditions is of critical importance: The IMF influences most observable properties of stellar populations and thus galaxies, and detecting variations ...

, 2012 We highlight the impact of cluster-mass-dependent evolutionary rates upon the evolution of the cluster mass function during violent relaxation, that is, while clusters dynamically respond to the expulsion of their residual star-forming gas.

Early Enrichment Population Theory at High Redshift
The Astrophysical JournalAn early enrichment population (EEP) has been theorized to produce the observed intracluster medium (ICM) metallicity of galaxy clusters. This population likely existed at high redshifts ( z ∼ 10), relics of which we posit exist today as dwarf galaxies.

On the Mass Distribution of Stellar-Mass Black Holes
Open Astronomy, 2014 The observational stellar-mass black hole mass distribution exhibits a maximum at about 8 M⊙. It can be explained via the details of the massive star evolution, supernova explosions, or consequent black hole evolution.

The Stellar Initial Mass Function of Early Dark Matter–free Gas Objects
The Astrophysical Journal LettersAmong the remarkable strides made by JWST is the discovery of the earliest star clusters found to date. These have been proposed as early progenitors of globular clusters, which are known to come from the early stages of star formation in the Universe ...

The Gaia-ESO Survey: membership and initial mass function of the γ Velorum cluster [PDF]
, 2016 Context. Understanding the properties of young open clusters, such as the Initial Mass Function (IMF), star formation history and dynamic evolution, is crucial to obtain reliable theoretical predictions of the mechanisms involved in the star formation ...

A Preferential Attachment Model for the Stellar Initial Mass Function
, 2019 Accurate specification of a likelihood function is becoming increasingly difficult in many inference problems in astronomy. As sample sizes resulting from astronomical surveys continue to grow, deficiencies in the likelihood function lead to larger ...
