The Extended Globular Cluster System of the archetypal "failed galaxy" Dragonfly-44 from deep white-light Hubble Space Telescope imaging
Maria Luisa Buzzo, Pieter van Dokkum, Roberto Abraham +2
Deep Hubble imaging reveals that the ultra-diffuse galaxy Dragonfly-44 hosts about 78 globular clusters, confirming its extremely high dark‑matter content and supporting its classi…
Dark matter-deficient twins: FCC 224 and FCC 240 as possible analogues of NGC 1052-DF2 and DF4
Maria Luisa Buzzo, Pieter van Dokkum, Michael Hilker +3
The recent "bullet-dwarf" model proposes that high-velocity collisions between dwarf galaxies can produce stellar systems with overluminous globular clusters (GCs) and a deficiency…
MATLAS-42, A Globular Cluster-Rich Ultra-Diffuse Galaxy That Diverges from the "Failed Galaxy'' Formation Pathway
Jonah S. Gannon, Duncan A. Forbes, Francine R. Marleau +4
To date, there has been significant interest in globular cluster (GC)-rich ultra-diffuse galaxies (UDGs) and the evidence that they have formed via an unexpected, ``failed galaxy''…
Connection Between Dwarf Galaxies and Globular Clusters: Insights from the Perseus Cluster Using Subaru Imaging and Keck Spectroscopy
Yimeng Tang, Aaron J. Romanowsky, Song Huang +11
We present a systematic study of 189 dwarf galaxies and their globular cluster (GC) systems in the Perseus cluster, based on deep Subaru Hyper Suprime-Cam imaging and Keck spectros…
Looking into the faintEst WIth MUSE (LEWIS): Exploring the nature of ultra-diffuse galaxies in the Hydra-I cluster IV. A study of the Globular Cluster population in four UDGs
Marco Mirabile, Michele Cantiello, Marina Rejkuba +20
As old stellar systems, globular clusters (GCs) are key fossil tracers of galaxy formation and interaction histories. This paper is part of the LEWIS project, an integral-field spe…
GAMA 526784: the progenitor of a globular cluster-rich ultra-diffuse galaxy? II. Molecular gas, neutral gas and environment
Maria Luisa Buzzo, Anita Zanella, Michael Hilker +3
Aims. We investigate the gas reservoirs, star formation (SF) properties, and environment of the ultra-diffuse galaxy GAMA526784 to understand its formation history, the efficiency…
