Implications for Galaxy Formation Models from Observations of Globular Clusters around Ultra-Diffuse Galaxies
Teymoor Saifollahi, Dennis Zaritsky, Ignacio Trujillo +5
We present an analysis of Hubble Space Telescope observations of globular clusters (GCs) in six ultra-diffuse galaxies (UDGs) in the Coma cluster, a sample that represents UDGs wit…
Detection of extragalactic Ultra-Compact Dwarfs and Globular Clusters using Explainable AI techniques
Mohammad Mohammadi, Jarvin Mutatiina, Teymoor Saifollahi +1
Compact stellar systems such as Ultra-compact dwarfs (UCDs) and Globular Clusters (GCs) around galaxies are known to be the tracers of the merger events that have been forming thes…
Extragalactic globular clusters with Euclid and other wide surveys
Ariane Lançon, S. Larsen, K. Voggel +14
Globular clusters play a role in many areas of astrophysics, ranging from stellar physics to cosmology. New ground-based optical surveys complemented by observations from space-bas…
Ultra-compact dwarfs beyond the centre of the Fornax galaxy cluster: Hints of UCD formation in low-density environments
Teymoor Saifollahi, Joachim Janz, Reynier F. Peletier +6
Ultra-compact dwarf galaxies (UCDs) were serendipitously discovered by spectroscopic surveys in the Fornax cluster twenty years ago. Nowadays, it is commonly accepted that many bri…
In search of the weirdest galaxies in the Universe
Job Formsma, Teymoor Saifollahi
Weird galaxies are outliers that have either unknown or very uncommon features making them different from the normal sample. These galaxies are very interesting as they may provide…
The number of globular clusters around the iconic UDG DF44 is as expected for dwarf galaxies
Teymoor Saifollahi, Ignacio Trujillo, Michael A. Beasley +2
There is a growing consensus that the vast majority of ultra-diffuse galaxies (UDGs) are dwarf galaxies. However, there remain a few UDGs that seem to be special in terms of their…
