Rotation Curves of 967 Spiral Galaxies [PDF]
The Astrophysical Journal Supplement Series, 1995 We present the rotation curves (RCs) of 967 spiral galaxies, obtained by folding and deprojecting the raw optical data by Mathewson et al. (1992). Out of these, we have identified 80 excellent RCs and 820 fair RCs. The 80 excellent RCs are smooth, symmetric, have negligible rms internal error, extend to at least the optical radius, and have high and ...

Rotation Curve of the Milky Way from Classical Cepheids [PDF]
Astrophysical Journal, 2018 Flat rotation curves of spiral galaxies are considered as an evidence for dark matter, but the rotation curve of the Milky Way is difficult to measure.

Theoretical Search for Gravitational Bound States of Tachyons
Particles, 2022 The mission here is to see if we can find bound states for tachyons in some gravitational environment. That could provide an explanation for the phenomena called Dark Matter. Starting with the standard Schwarzschild metric in General Relativity, which is

Galaxy rotation curves in modified gravity models [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 In this work, we investigate the possibility that the galaxy rotation curves can be explained in the framework of modified gravity models that introduce a Yukawa term in the gravitational potential.

The Rotation Curves of Galaxies [PDF]
Symposium - International Astronomical Union, 1975 Currently available data on rotation curves are reviewed. For curves derived from optical measurements the distribution of the ratios: the last measured point on a rotation curve to the optical radius of the galaxy has a median value of if Reference Catalogue radii are used and if Holmberg radii are used.

A Severe Challenge to the Modified Newtonian Dynamics Phenomenology in Our Galaxy
The Astrophysical Journal, 2023 Modified Newtonian dynamics (MOND) is one of the most popular alternative theories of dark matter to explain the missing mass problem in galaxies. Although it remains controversial regarding MOND as a fundamental theory, MOND phenomenology has been shown

Reports in Advances of Physical Sciences, 2023 Birkhoff’s theorem (1923) states that in the framework of General Relativity the only solution to the central symmetric gravitational field in vacuum is the Schwarzschild metric.

Rotation Curve and Mass Distribution in the Galactic Center - From Black Hole to Entire Galaxy [PDF]
, 2013 Analyzing high-resolution longitude-velocity (LV) diagrams of the Galactic Center observed with the Nobeyama 45-m telescope in the CO and CS line emissions, we obtain a central rotation curve of the Milky Way.

PROBES. I. A Compendium of Deep Rotation Curves and Matched Multiband Photometry
The Astrophysical Journal Supplement Series, 2022 We present the Photometry and Rotation Curve Observations from Extragalactic Surveys (PROBES) compendium of extended rotation curves for 3163 late-type spirals, with matching homogeneous multiband photometry for 1677 of them.
