The spatial distribution of star and cluster formation in M51
R. A. Scheepmaker, H. J. G. L. M. Lamers, P. Anders +1
Aims. We study the connection between spatially resolved star formation and young star clusters across the disc of M51. Methods. We combine star cluster data based on B, V, and I-b…
Spectroscopy of globular clusters in the low-luminosity spiral galaxy NGC 45
Marcelo D. Mora, Soeren S. Larsen, Markus Kissler-Patig
CONTEXT: Extragalactic globular clusters have been studied in elliptical galaxies and in a few luminous spiral galaxies, but little is known about globular clusters in low-luminosi…
A peculiar object in M51: fuzzy star cluster or a background galaxy?
R. A. Scheepmaker, H. J. G. L. M. Lamers, S. S. Larsen +1
Aims: We study a peculiar object with a projected position close to the nucleus of M51. It is unusually large for a star cluster in M51 and we therefore investigate the three most…
Resolving Extragalactic Star Clusters with HST/ACS
S. S. Larsen
With HST, colour-magnitude diagrams (CMDs) can be obtained for young star clusters well beyond the Local Group. Such data can help constrain cluster ages and metallicities, and als…
ACS imaging of star clusters in M51. I. Identification and radius distribution
R. A. Scheepmaker, M. R. Haas, M. Gieles +3
We use HST/ACS observations of the spiral galaxy M51 in F435W, F555W and F814W to select a large sample of star clusters with accurate effective radius measurements in an area cove…
Variation of the cluster luminosity function across the disk of M51
M. R. Haas, M. Gieles, R. A. Scheepmaker +3
We study the luminosity function (LF) of the star clusters in M51. Comparing the observed LF with the LF resulting from artificial cluster populations suggests that there exists an…
