The observation of quasars at very high redshift such as Pōniuā'ena is a challenge for
models of supermassive black hole (SMBH) formation. This work presents a study of SMBH …

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 …

The distribution of stars and stellar remnants (white dwarfs, neutron stars, and black holes)
within globular clusters holds clues about their formation and long-term evolution, with …

Recent observations of globular clusters (GCs) provide evidence that the stellar initial mass
function (IMF) may not be universal, suggesting specifically that the IMF grows increasingly …

Here we present a full description of the integrated galaxy-wide initial mass function (IGIMF)
theory in terms of the optimal sampling and compare it with available observations. Optimal …

We present a uniform analysis of the stellar initial mass function (IMF) from integrated light
spectroscopy of 15 compact stellar systems (11 globular clusters in M31 and 4 ultra compact …

Abstract The globular cluster 47 Tucanae (47 Tuc) is one of the most massive star clusters in
the Milky Way and is exceptionally rich in exotic stellar populations. For several decades it …

We investigate the dissolution process for dynamically evolving star clusters embedded in
an external tidal field by exploring the mocca survey data base I, with focus on the presence …

We study the formation of globular clusters (GCs) in massive compact clouds with the low
metallicity of Z= 10− 3 Z⊙ by performing three-dimensional radiative-hydrodynamic …

The recent discovery of supermassive black holes (SMBHs) in high mass ultra-compact
dwarf galaxies (UCDs) suggests that at least some UCDs are the nuclear star clusters of …
