Action-based distribution functions for spheroidal galaxy components
Lorenzo Posti, James Binney, Carlo Nipoti +1
We present an approach to the design of distribution functions that depend on the phase-space coordinates through the action integrals. The approach makes it easy to construct a dy…
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…
A fast and accurate method to compute the mass return from multiple stellar populations
F. Calura, L. Ciotti, C. Nipoti
The mass returned to the ambient medium by aging stellar populations over cosmological times sums up to a significant fraction (20% - 30% or more) of their initial mass. This conti…
The Effects of Galaxy Shape and Rotation on the X-ray Haloes of Early-Type Galaxies
Silvia Posacki, Silvia Pellegrini, Luca Ciotti
We present a detailed diagnostic study of the observed temperatures of the hot X-ray coronae of early-type galaxies. By extending the investigation carried out in Pellegrini (2011)…
Radiative Transfer and Radiative driving of Outflows in AGN and Starbursts
G. S. Novak, J. P. Ostriker, L. Ciotti
To facilitate the study of black hole fueling, star formation, and feedback in galaxies, we outline a method for treating the radial forces on interstellar gas due to absorption of…
Separable triaxial potential-density pairs in MOND
L. Ciotti, H. Zhao, T. de Zeeuw
We study mass models that correspond to MOND (triaxial) potentials for which the Hamilton-Jacobi equation separates in ellipsoidal coordinates. The problem is first discussed in th…
