Stellar streams around dwarf galaxies in the local Universe

Context. While mergers between massive galaxies and their dwarf satellites have been well studied, the properties of dwarf–dwarf satellite mergers are not well constrained. Stellar streams trace satellite disruption and, in the dwarf galaxy regime, are predicted to provide novel constraints on low-m...

Sumario:Context. While mergers between massive galaxies and their dwarf satellites have been well studied, the properties of dwarf–dwarf satellite mergers are not well constrained. Stellar streams trace satellite disruption and, in the dwarf galaxy regime, are predicted to provide novel constraints on low-mass galaxy evolution and dark matter. However, the mass ratios required to form these streams make them challenging to detect.
