An evolutionary continuum from nucleated dwarf galaxies to star clusters
Kaixiang Wang, Eric W. Peng, Chengze Liu +21
Systematic studies have revealed hundreds of ultra-compact dwarf galaxies (UCDs) in the nearby Universe. With half-light radii of approximately 10-100 parsecs and stellar mas…
Testing the Surface Brightness Fluctuation Method on Dwarf Galaxies in the COSMOS Field
Lauren M. Foster, James E. Taylor, John P. Blakeslee
Dwarf galaxies are important tracers of small-scale cosmological structure, yet much of our knowledge about these systems comes from the limited sample of dwarf galaxies within the…
Gathering Galaxy Distances in Abundance with Roman Wide-Area Data
John P. Blakeslee, Michele Cantiello, Michael J. Hudson +5
The extragalactic distance scale is fundamental to our understanding of astrophysics and cosmology. In recent years, the surface brightness fluctuation (SBF) method, applied in the…
Comparing Globular Cluster System Properties with Host Galaxy Environment
Kate Hartman, William E. Harris, John P. Blakeslee +2
We present Hubble Space Telescope photometry in optical (F475X) and near-infrared (F110W) bands of the globular cluster (GC) systems of the inner halos of a sample of 15 massive el…
Surface Brightness Fluctuations
Michele Cantiello, John P. Blakeslee
The Surface Brightness Fluctuation (SBF) method is a powerful tool for determining distances to early-type galaxies. The method measures the intrinsic variance in a galaxy's surfac…
Extragalactic Star Cluster Science with the Nancy Grace Roman Space Telescope's High Latitude Wide Area Survey and the Vera C. Rubin Observatory
Kristen C. Dage, Christopher Usher, Jennifer Sobeck +22
The Nancy Grace Roman Telescope's High Latitude Wide Area Survey will have a number of synergies with the Vera Rubin Observatory's Legacy Survey of Space and Time (LSST), particula…
