The VIRUS-dE Survey II: Cuspy and round halos in dwarf ellipticals -- A result of early assembly?
Mathias Lipka, Jens Thomas, Roberto Saglia +3
We analyze the dark matter (DM) halos of a sample of dwarf Ellitpicals (dE) and discuss cosmological and evolutionary implications. Using orbit modeling we recover their density sl…

The VIRUS-dE Survey I: Stars in dwarf elliptical galaxies - 3D dynamics and radially resolved stellar initial mass functions
Mathias Lipka, Jens Thomas, Roberto Saglia +9
We analyse the stellar structure of a sample of dwarf ellipticals (dE) inhabiting various environments within the Virgo cluster. Integral-field observations with a high spectral re…
