The luminosity function of young star clusters: implications for the maximum mass and luminosity of clusters (2005)

Gieles, Mark, Larsen, Soeren, Bastian, Nate, Stein, Ilaan

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...

Observational evidence for a truncation of the star cluster initial mass function at the high mass end (2005)

Gieles, Mark, Larsen, Soeren, Scheepmaker, Remco, Bastian, Nate, Haas, Marcel, Lamers, Henny

We present the luminosity function (LF) of star clusters in M51 based on HST/ACS observations taken as part of the Hubble Heritage project. The clusters are selected based on their size and with the...

Faint Fuzzies and the Formation of Lenticular Galaxies (2005)

Burkert, Andreas, Brodie, Jean, Larsen, Soeren

We investigate the dynamical state of a new class of extended star clusters, known as "Faint Fuzzies", that were discovered in two nearby S0 galaxies, NGC 1023 and NGC 3384. It is shown that the...
