It is well known that the Milgrom’s modified Newtonian dynamics (MOND) explains well the mass discrepancy problem in galaxy rotation curves. The MOND predicts a universal acceleration scale below which the Newtonian dynamics is still invalid. We get the universal acceleration scale of 1.02 × 10−10 m s−2 by using the Spitzer Photometry and Accurate Rotation Curves (SPARC) data set. Milgrom suggested that the acceleration scale may be a fingerprint of cosmology on local dynamics and related to… 
Is there a fundamental acceleration scale in galaxies?
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 acceleration scale in
Probing the universality of acceleration scale in modified Newtonian dynamics with SPARC galaxies
We probe the universality of acceleration scale in Milgrom's modified Newtonian dynamics (MOND) using the recently released rotation curve data from SPARC galaxies. We divide the SPARC data into
The radial acceleration relation in galaxy clusters
Recently, the discovery of the radial acceleration relation (RAR) in galaxies has been regarded as an indirect support of alternative theories of gravity such as modified Newtonian dynamics (MOND)
Testing the cosmic anisotropy with supernovae data: Hemisphere comparison and dipole fitting
The cosmological principle is one of the cornerstones in modern cosmology. It assumes that the universe is homogeneous and isotropic on cosmic scales. Both the homogeneity and the isotropy of the
Searching for a possible dipole anisotropy in acceleration scale with 147 rotationally supported galaxies
We report a dipole anisotropy on acceleration scale $g_{\dag}$ in local universe with 147 rotationally supported galaxies. We find that a monopole and dipole correction for the radial acceleration
Constraining the anisotropy of the Universe with the Pantheon supernovae sample
We test the possible dipole anisotropy of the Finslerian cosmological model and the other three dipole-modulated cosmological models, i.e. the dipole-modulated ΛCDM, wCDM and
Cosmic anisotropy and fast radio bursts
In the recent years, the field of fast radio bursts (FRBs) is thriving and growing rapidly. It is of interest to study cosmology by using FRBs with known redshifts. In the present work, we try to
Constraining the anisotropy of the Universe with the X-ray and UV fluxes of quasars
We test the anisotropy in the Finslerian cosmological model with the X-ray and ultraviolet (UV) fluxes of 808 quasars. The dipole amplitude is AD = 0.302 +0.185 −0.124 and the dipole direction points
An Alternative to Dark Matter? Part 3: An Open Universe (3 Gy to 76 Gy) Galaxies and Structures Rotation
A cosmological model was developed using the equation of state of photon gas, as well as cosmic time. The primary objective of this model is to see if determining the observed rotation speed of


Searching for a Cosmological Preferred Axis: Union2 Data Analysis and Comparison with Other Probes
We review, compare and extend recent studies searching for evidence for a preferred cosmological axis. We start from the Union2 SnIa dataset and use the hemisphere comparison method to search for a
Constraining anisotropy of the universe from different groups of type-Ia supernovae
Recently released Planck data and other astronomical observations show that the universe may be anisotropic on large scales. Inspired by this, anisotropic cosmological models have been proposed. We
Dwarf and low surface brightness (LSB) galaxies are ideal objects to test modified Newtonian dynamics (MOND), because in most of these galaxies the accelerations fall below the threshold where MOND
We present an analysis of 12 high-resolution galactic rotation curves from The HI Nearby Galaxy Survey (THINGS) in the context of modified Newtonian dynamics (MOND). These rotation curves were
(An)isotropy of the Hubble diagram: comparing hemispheres
Aims. We test the isotropy of the Hubble diagram. At small redshifts, this is possible without assumptions on the cosmic inventory and provides a fundamental test of the cosmological principle. At
Constraining the anisotropy of the universe from supernovae and gamma-ray bursts
Recently, an anisotropic cosmological model was proposed. An arbitrary one-form, which picks out a privileged axis in the universe, was added to the Friedmann Robertson Walker (FRW) line element. The
Milky Way Mass Models and MOND
Using the Tuorla-Heidelberg model for the mass distribution of the Milky Way, I determine the rotation curve predicted by MOND (modified Newtonian dynamics). The result is in good agreement with the
A Measurement of Large-Scale Peculiar Velocities of Clusters of Galaxies: Results and Cosmological Implications
Peculiar velocities of clusters of galaxies can be measured by studying the fluctuations in the cosmic microwave background (CMB) generated by the scattering of the microwave photons by the hot
Rings and Shells of “Dark Matter” as MOND Artifacts
MOND predicts that a mass, M, contained within its transition radius, rt ≡ (MG/a0)1/2, may exhibit a feature at about that radius in the form of a shell, or projected ring, in the deduced
Extended rotation curves of spiral galaxies: dark haloes and modified dynamics
Strict criteria are applied to the sample of spiral galaxies with measured rotation curves in order to select those objects for which the observed rotation curve is an accurate tracer of the radial
