It is widely accepted that the distribution function of the masses of young star clusters is universal and can be purely interpreted as a probability density distribution function with a constant upper mass limit. As a result of this picture the masses of the mostmassive objects are exclusively determined by the size of the sample. Here we show, with very high confidence, that the masses of the most-massive young star clusters in M33 decrease with increasing galactocentric radius in…

The star cluster mass--galactocentric radius relation: Implications for cluster formation
Whether or not the initial star cluster mass function is established through a universal, galactocentric-distance-independent stochastic process, on the scales of individual galaxies, remains an
On the origin of the Schechter-like mass function of young star clusters in disk galaxies
The mass function of freshly formed star clusters is empirically often described as a power law. However the cluster mass function of populations of young clusters over the scale of a galaxy has been
Massive stars can be efficiently ejected from their birth star clusters through encounters with other massive stars. We study how the dynamical ejection fraction of O star systems varies with the
Young massive clusters in the interacting LIRG Arp 299: evidence for the dependence of star cluster formation and evolution on environment
Archival WFC3/UVIS imaging of Arp 299 (NGC 3690E + NGC 3690W) is retrieved to investigate the young massive cluster (YMC) population of this ongoing merger. We extract 2182 cluster candidates,
Distribution of star formation rates during the rapid assembly of NGC 1399 as deduced from its globular cluster system
Ultra-compact dwarf galaxies (UCDs) share many properties with globular clusters (GCs) and are found in similar environments. A large sample of UCDs and GCs around NGC 1399, the central giant
The role of spiral arms in Milky Way star formation
What role does Galactic structure play in star formation? We have used the Herschel Infrared Galactic Plane Survey (Hi-GAL) compact-clump catalogue to examine trends in evolutionary stage over large
Mass distributions of star clusters for different star formation histories in a galaxy cluster environment
Clusters of galaxies usually contain rich populations of globular clusters (GCs). We investigate how different star formation histories (SFHs) shape the final mass distribution of star clusters. We
Impact of metallicity and star formation rate on the time-dependent, galaxy-wide stellar initial mass function
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 generally
Star-Formation Rates of Galaxies
The measured star-formation rates (SFRs) of galaxies comprise an important constraint on galaxy evolution and also on their cosmological boundary conditions. Any available tracer of the SFR depends
The chemical evolution of galaxies with a variable integrated galactic initial mass function
ABSTRACT Standard analytical chemical evolution modelling of galaxies has been assuming thestellar initial mass function (IMF) to be invariant and fully sampled allowing fractionsof massive stars to


The luminosity function of young star clusters: implications for the maximum mass and luminosity of clusters.
We introduce a method to relate a possible truncation of the star cluster mass function at the high mass end to the shape of the cluster luminosity function (LF). We compare the observed LFs of five

The mass function of the young star clusters in the merging galaxies known as the "Antennae" (NGC 4038/9) is found to be well represented by a power law of the form psi&parl0;M&parr0;~M-2 over the range 104 less, similarMLess, similar106 M middle dot in circle.
What determines the mass of the most massive star cluster in a galaxy: statistics, physics or disruption?
In many different galactic environments the cluster initial mass function (CIMF) is well described by a power law with index −2. This implies a linear relation between the mass of the most massive
The Initial Mass Function of Stars: Evidence for Uniformity in Variable Systems
Combining IMF estimates for different populations in which the stars can be observed individually unveils an extraordinary uniformity of the IMF, which appears to hold for populations including present-day star formation in small molecular clouds.
The maximum stellar mass, star-cluster formation and composite stellar populations
We demonstrate that the mass of the most massive star in a cluster correlates non-trivially with the cluster mass. A simple algorithm, according to which a cluster is filled up with stars that are
Implications for the formation of star clusters from extragalactic star formation rates
Observations indicate that young massive star clusters in spiral and dwarf galaxies follow a relation between luminosity of the brightest young cluster and the star formation rate (SFR) of the host

Aims. The properties of young stellar clusters (YSCs) in M33, identified from the center out to about twice the size of the bright star-forming disk, are investigated to determine possible spatial

Using our Binary Population And Spectral Synthesis (bpass) code we explore the effects on star formation rate indicators of stochastically sampling the stellar initial mass function (IMF), adding a
Galactic-Field Initial Mass Functions of Massive Stars
Over the past years observations of young and populous star clusters have shown that the stellar initial mass function (IMF) appears to be an invariant featureless Salpeter power law with an exponent
