Polar ring galaxies as tests of gravity
F. Lüghausen, B. Famaey, P. Kroupa +5
Polar ring galaxies are ideal objects with which to study the three-dimensional shapes of galactic gravitational potentials since two rotation curves can be measured in two perpend…
The inner structure of very massive elliptical galaxies: implications for the inside-out formation mechanism of z~2 galaxies
O. Tiret, P. Salucci, M. Bernardi +2
We analyze a sample of 23 supermassive elliptical galaxies (central velocity dispersion larger than 330 km s-1), drawn from the SDSS. For each object, we estimate the dynamical mas…
Dark Matter tested with satellites
F. Combes, O. Tiret
Recently, the distribution of velocity dispersion as far as 400kpc around red isolated galaxies was derived from statistical studies of satellites in the SDSS (Klypin & Prada 2009)…
MOND and the Galaxies
F. Combes, O. Tiret
We review galaxy formation and dynamics under the MOND hypothesis of modified gravity, and compare to similar galaxies in Newtonian dynamics with dark matter. The aim is to find pe…
MOND and the dark baryons
O. Tiret, F. Combes
We consider for the first time the implications on the modified gravity MOND model of galaxies, of the presence of dark baryons, under the form of cold molecular gas in galaxy disc…
Evolution of spiral galaxies in modified gravity: II- Gas dynamics
O. Tiret, F. Combes
The stability of spiral galaxies is compared in modified Newtonian Dynamics (MOND) and Newtonian dynamics with dark matter (DM). We extend our previous simulations that involved pu…
