A 3D view of dwarf galaxies with Gaia and VLT/FLAMES: II. the Sextans dwarf spheroidal

Salvatore Taibi

The Sextans dwarf spheroidal galaxy has been challenging to study in a comprehensive way as it is highly extended on the sky, with an uncertain but large tidal radius of between 80- 160 arcminutes (or 3- 4 kpc), and an extremely low central surface brightn ...

The effect of measurement uncertainties on the inferred stability of planes of satellite galaxies

Salvatore Taibi

Context. Observations have revealed that the Milky Way, Andromeda, Centaurus A, and possibly other galaxies host spatially thin and kinematically coherent planes of satellites. Such structures are highly improbable within the standard ΛCDM cosmological mod ...

MUSE observations of dwarf galaxies and a stellar stream in the M 83 group

Oliver Müller, Nick Heesters, Salvatore Taibi

Spectroscopy for faint dwarf galaxies outside of our own Local Group is challenging. Here, we present MUSE spectroscopy to study the properties of four known dwarf satellites and one stellar stream (KK 208) surrounding the nearby grand spiral M 83, which r ...

An LBT view of the co-rotating group of galaxies around NGC2750: Deep imaging and new satellite candidates

Olivia Mueller, Salvatore Taibi

Context. Some galaxies such as the Milky Way and Andromeda display coherently rotating satellite planes, posing tensions with cosmological simulations. NGC2750 has emerged as an additional candidate system hosting a co-rotating group of galaxies. Aims. Thi ...
