Radially anisotropic systems with forces. II: radial-orbit instability
Pierfrancesco Di Cintio, Luca Ciotti, Carlo Nipoti
We continue to investigate the dynamics of collisionless systems of particles interacting via additive interparticle forces. Here we focus on the dependence of the radial-…
Paving the way for the JWST: witnessing globular cluster formation at z>3
E. Vanzella, F. Calura, M. Meneghetti +17
We report on five compact, extremely young (<10Myr) and blue (β_UV<-2.5, F_λ=λ^β) objects observed with VLT/MUSE at redshift 3.1169, 3.235, in addition to three objects at z=6.145.…
The Effect of the AGN Feedback on the Interstellar Medium of Early-Type Galaxies: 2D Hydrodynamical Simulations of the Low-Rotation Case
L. Ciotti, S. Pellegrini, A. Negri +1
We present 2D hydrodynamical simulations for the evolution of early-type galaxies containing central massive black holes (MBHs), starting at age 2 Gyr. The code contains accurate a…
DDO 68: A flea with smaller fleas that on him prey
F. Annibali, C. Nipoti, L. Ciotti +7
We present new photometry of the dwarf irregular galaxy DDO 68, one of the most metal-poor and least massive dwarfs, located in the Lynx-Cancer Void. The images were acquired with…
The mass discrepancy acceleration relation in early-type galaxies: extended mass profiles and the phantom menace to MOND
Joachim Janz, Michele Cappellari, Aaron J. Romanowsky +3
The dark matter (DM) haloes around spiral galaxies appear to conspire with their baryonic content: empirically, significant amounts of DM are inferred only below a universal charac…
Bondi accretion in early-type galaxies
V. Korol, L. Ciotti, S. Pellegrini
Accretion onto central massive black holes in galaxies is often modelled with the Bondi solution. In this paper we study a generalization of the classical Bondi accretion theory, c…
