Fast galaxy bars continue to challenge standard cosmology
Mahmood Roshan, Neda Ghafourian, Tahere Kashfi +5
Many observed disc galaxies harbour a central bar. In the standard cosmological paradigm, galactic bars should be slowed down by dynamical friction from the dark matter halo. This…

Barred spiral galaxies in modified gravity theories
Mahmood Roshan, Indranil Banik, Neda Ghafourian +4
When bars form within galaxy formation simulations in the standard cosmological context, dynamical friction with dark matter (DM) causes them to rotate rather slowly. However, almo…
