Revisiting perfect fluid dark matter: Observational constraints from our galaxy
Physics Letters B, 2016 We revisit certain features of an assumed spherically symmetric perfect fluid dark matter halo in the light of the observed data of our galaxy, the Milky Way (MW). The idea is to apply the Faber–Visser approach of combined observations of rotation curves

The AGN and Gas Disk in the Low Surface Brightness Galaxy PGC045080 [PDF]
, 2007 We present radio observations and optical spectroscopy of the giant low surface brightness (LSB) galaxy PGC 045080 (or 1300+0144). PGC 045080 is a moderately distant galaxy having a highly inclined optical disk and massive HI gas content. Radio continuum

galkin: A new compilation of Milky Way rotation curve data
SoftwareX, 2017 We present galkin, a novel compilation of kinematic measurements tracing the rotation curve of our Galaxy together with a tool to treat the data. The compilation is optimised to Galactocentric radii between 3 and 20 kpc and includes the kinematics of gas,

Dark Matter Dogma: A Study of 214 Galaxies
Galaxies, 2020 The aim of this paper is to test the need for non-baryonic dark matter in the context of galactic rotation and the apparent difference between distributions of galactic mass and luminosity.

Rotation curves of galaxies by fourth order gravity [PDF]
Physical Review D, 2011 We investigate the radial behavior of galactic rotation curves by a Fourth Order Gravity adding also the Dark Matter component. The Fourth Order Gravity is a Lagrangian containing the Ricci scalar, the Ricci and Riemann tensor, but the rotation curves are depending only on two free parameters.

Light deflection angle through velocity profile of galaxies in f(R) model
European Physical Journal C: Particles and Fields, 2021 We explore a new realisation of the galactic scale dynamics via gravitational lensing phenomenon in power-law f(R) gravity theory of the type $$f(R)\propto R^{1+\delta }$$ f ( R ) ∝ R 1 + δ with ...

Outer Rotation Curve of the Galaxy with VERA I: Trigonometric Parallax of IRAS 05168+3634 [PDF]
, 2012 We report measurement of trigonometric parallax of IRAS 05168+3634 with VERA. The parallax is 0.532 ± 0.053 mas, corresponding to a distance of 1.88 −0.17 kpc.

Rotation curve for the Milky Way galaxy in conformal gravity
, 2015 Galactic rotation curves have proven to be the testing ground for dark matter bounds in galaxies, and our own Milky Way is one of many large spiral galaxies that must follow the same models.
