The Next Generation Fornax Survey (NGFS): VII. A MUSE view of the nuclear star clusters in Fornax dwarf galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT Clues to the formation and evolution of nuclear star clusters (NSCs) lie in their stellar populations. However, these structures are often very faint compared to their host galaxy, and spectroscopic analysis of NSCs is hampered by contamination of light from the rest of the system.

Star Cluster Demographics. I. A General Framework and Application to the Antennae Galaxies [PDF]

The Astronomical Journal, 2007
We present a framework for understanding the demographics of star cluster systems, and develop a toy model which incorporates a universal initial power law mass function, selected formation histories, selected disruption laws, and a convolution with common artifacts and selection effects found in observational data. The model confirms that the observed

The Next Generation Virgo Cluster Survey. XXIII. Fundamentals of Nuclear Star Clusters over Seven Decades in Galaxy Mass [PDF]

The Astrophysical Journal, 2019
Abstract Using deep, high-resolution optical imaging from the Next Generation Virgo Cluster Survey, we study the properties of nuclear star clusters (NSCs) in a sample of nearly 400 quiescent galaxies in the core of Virgo with stellar masses 105 ≲  /

Young massive star clusters in nearby galaxies. I. Identification and general properties of cluster systems

, 1999
Using ground-based UBVRI+Halpha CCD photometry we have been carrying out a search for young massive star clusters (YMCs) in a sample consisting of 21 nearby spiral galaxies. We find a large variety concerning the richness of the cluster systems, with some galaxies containing no YMCs at all and others hosting very large numbers of YMCs.

A colour–colour fingerprint links the UV upturn in early-type galaxies to second-generation stars from dissolved globular clusters

Monthly Notices of the Royal Astronomical Society
ABSTRACT We address two mass-dependent properties among early-type galaxies (ETGs): (1) abundance ratios [N/Fe] and [Na/Fe], and (2) the centrally concentrated ‘UV upturn’ at far-UV (FUV) wavelengths, which is likely produced by extreme horizontal branch stars with supersolar helium abundances.
