The Astrophysical JournalRecent measurements of the Milky Way rotation curve found a sharp decline at around 15–20 kpc from the center of the Galaxy, suggesting that the Galactic dark matter halo is much less massive than predicted by other dynamical tracers.

Newtonian Gravity and Galaxy Rotation Curves: An Axisymmetric Green's Function Perspective [PDF]
The standard proposal within the context of General relativity and its weak field Newtonian limit for the nature of dark matter is that it consists of dark matter particles of unknown type.

The Nearly Universal Disk Galaxy Rotation Curve
The Astrophysical JournalThe universal rotation curve (URC) of disk galaxies was originally proposed to predict the shape and amplitude of any rotation curve (RC) based solely on photometric data.

Perfect fluid dark matter: a viability test with galaxy rotation curves
European Physical Journal C: Particles and FieldsThe anomalous rotation curves of galaxies provide compelling evidence for dark matter, yet its fundamental nature and distribution remain key unresolved issues in astrophysics.

The Astrophysical JournalWe characterize stellar, gas, and dark matter mass distributions for 17 nearby massive disk galaxies from the PHANGS sample. This allows us to compute the gravitational potential that vertically confines the interstellar gas and determines its ...

Declining rotation curves in interacting galaxies [PDF]
, 1993 A declining rotation curve was recently found for the galaxy NGC 3521 by HI synthesis telescope observations (Casertano and van Gorkom 1991). From a comparison of the shapes of rotation curves for a larger sample of galaxies Casertano and van Gorkom ...

AIP AdvancesThe free electron model with Boltzmann statistics for spherical low-density plasmas is developed further, with asymptotic relations obtaining the density of electrons, mass densities, and the potentials of such plasmas.

The Astrophysical JournalWe use the IllustrisTNG cosmological hydrodynamical simulation to study the rotation curves of galaxies in the local universe. To do that, we first select the galaxies with 9.4

The Astrophysical JournalA unique galaxy at z = 2.2, zC406690, has a striking clumpy large-scale ring structure that persists from rest-frame UV to near-infrared, yet has an ordered rotation and lies on the star formation main sequence.
