Triaxial Schwarzschild Models of Brightest Cluster Galaxies with Long-Slit LBT Data
Stefano de Nicola, Roberto P. Saglia, Jens Thomas +3
We present new long-slit stellar kinematics for a sample of 21 Brightest Cluster Galaxies (BCGs) and triaxial Schwarzschild models for 16 of these objects using our orbit modelling…
Eight New Ultramassive Black Hole Masses confirm Best Correlation with Galaxy Core Sizes
Stefano de Nicola, Jens Thomas, Roberto P. Saglia +3
We analyse black-hole scaling relations at the high-mass end, focusing in particular on the regime of ultra-massive black holes, $\mathrm{M}_\mathrm{BH} > 10^{10}\,\mathrm{M}_\odot…
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…
Triaxial Schwarzschild Models of NGC 708: a 10-billion solar mass black hole in a low dispersion galaxy with a Kroupa IMF
Stefano de Nicola, Jens Thomas, Roberto P. Saglia +3
We report the discovery of a M Supermassive Black Hole (BH) at the centre of NGC 708, the Brightest Cluster Galaxy of Abell 262. Such high B…
