Globular cluster Observations for Luminosity-dispersion Distances (GOLD): Project description and velocity catalogue
K. Fahrion, M. A. Beasley, A. Gvozdenko +10
We introduce and describe the Globular cluster Observations for Luminosity-Dispersion distances (GOLD) project, which has the principal aim of determining independent distances bas…

Decomposing cool stellar populations with H-band spectral fluctuations: Long-period variable stars in NGC 5128 and carbon stars in NGC 5102
Russell J. Smith, Anastasia Gvozdenko
We analyse new H-band integral-field unit observations of two galaxies at ~4 Mpc, using a principal components analysis of pixel spectra to probe their giant star content. In both…

Extragalactic archaeology through high-resolution integrated-light spectroscopy of globular clusters
M. A. Beasley, K. Fahrion, A. Gvozdenko +1
We propose to radically expand the use of extragalactic globular clusters as tools for extragalactic archaeology. We propose a large-scale spectroscopic facility to obtain high spe…
