Can dry merging explain the size evolution of early-type galaxies?
C. Nipoti, T. Treu, M. W. Auger +1
The characteristic size of early-type galaxies (ETGs) of given stellar mass is observed to increase significantly with cosmic time, from redshift z>2 to the present. A popular expl…
Stationary models for the extra-planar gas in disc galaxies
F. Marinacci, F. Fraternali, L. Ciotti +1
The kinematics of the extra-planar neutral and ionised gas in disc galaxies shows a systematic decline of the rotational velocity with height from the plane (vertical gradient). Th…
Globular clusters in modified Newtonian dynamics: velocity-dispersion profiles from self-consistent models
A. Sollima, C. Nipoti
We test the modified Newtonian dynamics (MOND) theory with the velocity-dispersion profiles of Galactic globular clusters populating the outermost region of the Milky Way halo, whe…
Cool gas accretion, thermal evaporation and quenching of star formation in elliptical galaxies
Carlo Nipoti
The most evident features of colour-magnitude diagrams of galaxies are the red sequence of quiescent galaxies, extending up to the brightest elliptical galaxies, and the blue cloud…
Dry mergers and the formation of early-type galaxies: constraints from lensing and dynamics
Carlo Nipoti, Tommaso Treu, Adam S. Bolton
Dissipationless (gas-free or "dry") mergers have been suggested to play a major role in the formation and evolution of early-type galaxies, particularly in growing their mass and s…
Cusp-core dichotomy of elliptical galaxies: the role of thermal evaporation
Carlo Nipoti
There are two families of luminous elliptical galaxies: cusp galaxies, with steep central surface-brightness profiles, and core galaxies, whose surface-brightness profiles have fla…
