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…
The face-on projection of the Miyamoto & Nagai disks
Luca Ciotti
The face-on projected density profile of the Miyamoto & Nagai disks of arbitrary flattening is obtained analytically in terms of incomplete elliptic integrals of first and second t…
Rotation curves of galaxies in GR
Luca Ciotti
It has been suggested that the observed flat rotation curves of disk galaxies can be a peculiar effect of General Relativity (GR) rather than evidence for the presence of dark matt…
Active galactic nuclei feedback in an elliptical galaxy (III): the impacts and fate of cosmological inflow
Bocheng Zhu, Feng Yuan, Suoqing Ji +4
The cosmological inflow of a galaxy is speculated to be able to enter the galaxy and enhance the star formation rate (SFR) and black hole accretion rate (BHAR). In this paper, by p…
Chemical evolution of elliptical galaxies I: supernovae and AGN feedback
Marta Molero, Francesca Matteucci, Luca Ciotti
We study the formation and evolution of elliptical galaxies and how they suppress star formation and maintain it quenched. A one-zone chemical model which follows in detail the tim…
