Velocity dispersion around ellipticals in MOND
O. Tiret, F. Combes, G. W. Angus +2
We investigate how different models that have been proposed for solving the dark matter problem can fit the velocity dispersion observed around elliptical galaxies, on either a sma…
The velocity distribution of SDSS satellites in MOND
Garry Angus, Benoit Famaey, Olivier Tiret +2
The recent SDSS measured velocity distribution of satellite galaxies has been modelled in the context of MOND. We show that even when the extra constraint of adhering to the projec…
X-ray Group and cluster mass profiles in MOND: Unexplained mass on the group scale
Garry W. Angus, Benoit Famaey, David A. Buote
Although very successful in explaining the observed conspiracy between the baryonic distribution and the gravitational field in spiral galaxies without resorting to dark matter (DM…
Loss of mass and stability of galaxies in MOND
Xufen Wu, HongSheng Zhao, Benoit Famaey +5
The self-binding energy and stability of a galaxy in MOND-based gravity are curiously decreasing functions of its center of mass acceleration towards neighbouring mass concentratio…
The wedding of modified dynamics and non-exotic dark matter in galaxy clusters
B. Famaey, G. W. Angus, G. Gentile +2
We summarize the status of Modified Newtonian Dynamics (MOND) in galaxy clusters. The observed acceleration is typically larger than the acceleration threshold of MOND in the centr…
The collision velocity of the bullet cluster in conventional and modified dynamics
Garry W. Angus, Stacy S. McGaugh
We consider the orbit of the bullet cluster 1E 0657-56 in both CDM and MOND using accurate mass models appropriate to each case in order to ascertain the maximum plausible collisio…
