Differences between the globular cluster systems of the Virgo and Fornax Galaxy Clusters
J. Dabringhausen, M. Fellhauer, S. Mieske
It is well known that Globular cluster systems are different among galaxies. Here we test to which degree these differences remain on the scale of galaxy clusters by comparing the…
A Deep View into the Nucleus of the Sagittarius Dwarf Spheroidal Galaxy with MUSE. III. Discrete multi-component population-dynamical models based on the Jeans equations
Nikolay Kacharov, Mayte Alfaro-Cuello, Nadine Neumayer +12
We present comprehensive multi-component dynamical models of M54 (NGC6715), the nuclear star cluster of the Sagittarius dwarf galaxy (Sgr), which is undergoing a tidal disruption i…
The SAMI -- Fornax Dwarfs Survey II: The Stellar Mass Fundamental Plane and the Dark Matter fraction of Dwarf Galaxies
F. Sara Eftekhari, Reynier F. Peletier, Nicholas Scott +14
We explore the kinematic scaling relations of 38 dwarf galaxies in the Fornax Cluster using observations from the SAMI integral field spectrograph. We focus on the Fundamental Plan…
The distribution and morphologies of Fornax Cluster dwarf galaxies suggest they lack dark matter
E. Asencio, I. Banik, S. Mieske +3
Due to their low surface brightness, dwarf galaxies are particularly susceptible to tidal forces. The expected degree of disturbance depends on the assumed gravity law and whether…
Properties of intra-cluster low-mass X-ray binaries in Fornax globular clusters
G. Riccio, M. Paolillo, M. Cantiello +9
We present a study of the intra-cluster population of low-mass X-ray binaries (LMXB) residing in globular clusters (GC) in the central 1 of the Fornax galaxy cluster. Diffe…
Galaxy populations in the Hydra I cluster from the VEGAS survey II. The ultra-diffuse galaxy population
Antonio La Marca, Enrichetta Iodice, Michele Cantiello +18
In this work, we extend the catalog of low-surface brightness (LSB) galaxies, including Ultra-Diffuse Galaxy (UDG) candidates, within of the Hydra I cluster of…
