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…
Tracing the relic nature of compact galaxies through their globular cluster systems
Micheli T. Moura, Ana L. Chies-Santos, Cristina Furlanetto +6
We investigate the synthetic model of globular cluster (GC) systems of 17 compact massive galaxies (CMGs) from the Illustris TNG100 simulation to explore their connection with mass…
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…
Connecting galaxies with their haloes -- from parsec to Mpc scales
K. Fahrion, J. van de Sande, K. R. Akhil +12
Galaxy evolution is driven by processes occurring across a wide range of scales, from star formation within giant molecular clouds (parsec scales) to outflows and secular evolution…
ILLUSTRating red nugget assembly through observations and simulations
Micheli T. Moura, Anna Ferré-Mateu, Ana L. Chies-Santos +2
The properties of massive and compact early-type galaxies provide important constraints on early galaxy formation. Among these, massive relic galaxies, characterized by old stellar…
Distance measurements from the internal dynamics of globular clusters: Application to the Sombrero galaxy (M104)
Katja Fahrion, Michael A. Beasley, Anastasia Gvozdenko +7
Globular clusters (GCs) are dense star clusters found in all massive galaxies. Recent work has established that they follow a tight relation between their internal stellar velocity…
Globular clusters in M104: Tracing kinematics and metallicities from the centre to the halo
Katja Fahrion, Michael A. Beasley, Eric Emsellem +4
As ancient star clusters, globular clusters (GCs) are regarded as powerful tracers of galaxy evolution and assembly. Due to their brightness and compact sizes, GCs are employed to…
Revisiting the globular clusters of NGC1052-DF2
K. Fahrion, M. A. Beasley, A. Gvozdenko +4
The ultra-diffuse galaxy (UDG) NGC1052-DF2 has captured the interest of astronomers ever since the low velocity dispersion measured from ten globular clusters (GCs) suggested a low…
A new way to measure the distance to NGC1052-DF2
Michael A. Beasley, Katja Fahrion, Sergio Guerra Arencibia +2
We employ a new way to measure the distance to NGC1052-DF2 via internal stellar velocity dispersions () of its globular clusters (GCs). We obtained deep (15.1h), R=18,200, Ca Tr…
