On the absence of a universal surface density, and a maximum Newtonian acceleration in dark matter haloes: consequences for MOND

Yong Zhou, A. Del Popolo, Zhe Chang

We study the dark matter (DM) surface density using the SPARC sample and {compare} it to Donato et al. (2009) result. By means of MCMC method, we infer the best-fitting parameters…

Anisotropy of the Universe via the Pantheon supernovae sample revisited

Dong Zhao, Yong Zhou, Zhe Chang

We employ the hemisphere comparison (HC) method and the dipole fitting (DF) method to investigate the cosmic anisotropy in the recently released Pantheon sample of type Ia supernov…

Is there a fundamental acceleration scale in galaxies?

Zhe Chang, Yong Zhou

Milgrom's modified Newtonian dynamics (MOND) can explain well the mass discrepancy problem in galaxy without invoking dark matter. The MOND theory predicts a universal constant acc…

Finsler space-time can explain both parity asymmetry and power deficit seen in CMB temperature anisotropies

Zhe Chang, Pranati K. Rath, Yu Sang +2

We propose a framework of Finsler space-time to explain the observed parity asymmetry and the power deficit in the low- () multipole range of co…

Searching for a possible dipole anisotropy on acceleration scale with 147 rotationally supported galaxies

Zhe Chang, Hai-Nan Lin, Zhi-Chao Zhao +1

We report a possible dipole anisotropy on acceleration scale with 147 rotationally supported galaxies in local Universe. It is found that a monopole and dipole correction for…

Searching for a cosmological preferred direction with 147 rotationally supported galaxies

Yong Zhou, Zhi-Chao Zhao, Zhe Chang

It is well known that the Milgrom's MOND (modified Newtonian dynamics) explains well the mass discrepancy problem in galaxy rotation curves. The MOND predicts a universal accelerat…
