Understanding Galaxy Rotation Curves with Verlinde's Emergent Gravity [PDF]
, 2022 We present the results from the analysis of galaxy rotation curves with Verlinde's emergent gravity. We use the data in the SPARC (Spitzer Photometry and Accurate Rotation Curves) database, which contains a sample of 175 nearby disk galaxies with 3.6 ...

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 Galaxy [PDF]
Publications of the Astronomical Society of Japan, 1997 Reanalyzing the galactic HI survey data with two methods which make use of the geometry of the galactic disk, we explore the outer rotation curve. In addition to the derivation of the outer rotation curve, we investigate their uncertainties, which have not been established previously.

On Filaments, Prolate Halos and Rotation Curves [PDF]
The 1st Electronic Conference on Universe, 2021 Abstract We propose a simple geometrical mechanism for the flattening of galactic rotation curves, the local compression of field lines around their planes induced either by the presence of thin string-like objects at the centers of galaxies or by elongated dark-matter halos, and elaborate on its possible role in Nature.

Dark matter fluid constraints from galaxy rotation curves
European Physical Journal C: Particles and Fields, 2023 Galaxy rotation curves are considered to be convincing evidence for dark matter or some dynamically equivalent alternative mechanism. Starting only from the rotation curve data, we present a model independent approach of testing a general hypothesis that

A Simple Model for Explaining Galaxy Rotation Curves
Galaxies, 2018 A new simple expression for the circular velocity of spiral galaxies is proposed and tested against HI Nearby Galaxy Survey (THINGS) data set. Its accuracy is compared with the one coming from MOND.

Declining Rotation Curves at High Redshift?
, 2017 A recent paper in Nature by Genzel et al. reports declining rotation curves for high redshift galaxies. I have been getting a lot of questions about this result, which would be very important if true. So I thought I'd share a few thoughts here. Nature is

Galaxies, 2018 Spiral galaxies are spinning, internally densified objects. The Virial Theorem explains galactic rotation curves via its linkage of the rotation rate to the gravitational self-potential (Ug) and the moment of inertia of oblate spheroids.
