Miyamoto-Nagai discs embedded in the Binney logarithmic potential: analytical solution of the two-integrals Jeans equations
Christophe O. Smet, Silvia Posacki, Luca Ciotti
We present the analytical solution of the two-integrals Jeans equations for Miyamoto-Nagai discs embedded in Binney logarithmic dark matter haloes. The equations can be solved (bot…
The stellar initial mass function of early type galaxies from low to high stellar velocity dispersion: homogeneous analysis of ATLAS and Sloan Lens ACS galaxies
Silvia Posacki, Michele Cappellari, Tommaso Treu +2
We present an investigation about the shape of the initial mass function (IMF) of early-type galaxies (ETGs), based on a joint lensing and dynamical analysis, and on stellar popula…
The effects of galaxy shape and rotation on the X-ray haloes of early-type galaxies - II. Numerical simulations
Andrea Negri, Silvia Posacki, Silvia Pellegrini +1
By means of high resolution 2D hydrodynamical simulations, we study the evolution of the hot ISM for a large set of early-type galaxy models, characterized by various degrees of fl…
