Anisotropy ansatz for the Jeans equations: oblate galaxies

Leonardo De Deo, Luca Ciotti, Silvia Pellegrini

In the solution of the Jeans equations for axisymmetric galaxy models the ``-ansatz" is often adopted to prescribe the relation between the vertical and radial components of the…

Anisotropy ansatz for the axisymmetric Jeans equations

Leonardo De Deo, Luca Ciotti, Silvia Pellegrini

The Jeans equations do not form a closed system, and to solve them a parametrization relating the velocity moments is often adopted. For axisymmetric models, a phenomenological cho…

Jeans modelling of weakly flattened stellar systems

Antonio Mancino, Luca Ciotti, Silvia Pellegrini +1

In the homoeoidal expansion, a given ellipsoidally stratified density distribution, and its associated potential, are expanded in the (small) density flattening parameter , and…

Fully analytical solutions for Bondi accretion in galaxies with a central Black Hole

L. Ciotti, S. Pellegrini

The fully analytical solution for isothermal Bondi accretion on a black hole (MBH) at the center of JJ two-component Jaffe (1983) galaxy models is presented. In JJ models the stell…

The effects of stellar dynamics on the X-ray emission of flat early-type galaxies

Andrea Negri, Luca Ciotti, Silvia Pellegrini

Observational and numerical studies gave hints that the hot gaseous haloes of ETGs may be sensitive to the galaxy internal kinematics. By using high resolution 2D hydro simulations…

Clues on black hole feedback from simulated and observed X-ray properties of elliptical galaxies

S. Pellegrini, L. Ciotti, J. P. Ostriker

The centers of elliptical galaxies host supermassive black holes that significantly affect the surrounding interstellar medium through feedback resulting from the accretion process…
