Revisiting cosmic anisotropy with the Pantheon+ compilation
Yong Zhou, Dong Zhao
We investigate cosmic anisotropy within the updated Pantheon+ sample using both the dipole fitting (DF) and hemisphere comparison (HC) methods. With the DF method, the dipole signa…
Multi-TeV photons from GRB 221009A: uncertainty of optical depth considered
Zhi-Chao Zhao, Yong Zhou, Sai Wang
It is reported that the Large High Altitude Air Shower Observatory (LHAASO) observed thousands of very-high-energy photons up to 18 TeV from GRB 221009A. We study the surviva…
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…
