HST resolves stars in a tiny body falling on the dwarf galaxy DDO 68
F. Annibali, M. Bellazzini, M. Correnti +9
We present new Hubble Space Telescope (HST) imaging of a stream-like system associated with the dwarf galaxy DDO 68, located in the Lynx-Cancer Void at a distance of D12.65 M…
Two-component Jaffe models with a central black hole. I: the spherical case
L. Ciotti, A. Ziaee Lorzad
Dynamical properties of spherically symmetric galaxy models where both the stellar and total mass density distributions are described by the Jaffe (1983) profile (with different sc…
Radially anisotropic systems with forces: equilibrium states
Pierfrancesco Di Cintio, Luca Ciotti, Carlo Nipoti
We continue the study of collisionless systems governed by additive interparticle forces by focusing on the influence of the force exponent on radial orbital anisotrop…
The imprint of dark matter haloes on the size and velocity dispersion evolution of early-type galaxies
Lorenzo Posti, Carlo Nipoti, Massimo Stiavelli +1
Early-type galaxies (ETGs) are observed to be more compact, on average, at than at , at fixed stellar mass. Recent observational works suggest that such si…
Fountain-driven gas accretion by the Milky Way
F. Marinacci, F. Fraternali, J. Binney +3
Accretion of fresh gas at a rate of ~ 1 M_{sun} yr^{-1} is necessary in star-forming disc galaxies, such as the Milky Way, in order to sustain their star-formation rates. In this w…
Galactic fountains and gas accretion
F. Marinacci, J. Binney, F. Fraternali +3
Star-forming disc galaxies such as the Milky Way need to accrete $\gsim$ 1 of gas each year to sustain their star formation. This gas accretion is likely to come from t…
