The universal rotation curve of dwarf disc galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We use the concept of the spiral rotation curves universality to investigate the luminous and dark matter properties of the dwarf disc galaxies in the local volume (size $\sim11$ Mpc). Our sample includes 36 objects with rotation curves carefully selected from the literature.

Modeling of Spiral Structure in a Multi-Component Milky Way-Like Galaxy
Galaxies, 2021 Using recent observational data, we construct a set of multi-component equilibrium models of the disk of a Milky Way-like galaxy. The disk dynamics are studied using collisionless-gaseous numerical simulations, based on the joined integration of the ...

On the density within the dark-matter core in our galaxy [PDF]
Serbian Astronomical Journal, 2007 Assuming that the disc of our Galaxy, the Milky Way, obeys the classical exponential law, that it is maximal and the Sun is rather far from the maximum of its circular velocity, one finds that, most likely, the galactic corona (subsystem containing the ...

Mass Distribution in Rotating Thin-Disk Galaxies According to Newtonian Dynamics
Galaxies, 2014 An accurate computational method is presented for determining the mass distribution in a mature spiral galaxy from a given rotation curve by applying Newtonian dynamics for an axisymmetrically rotating thin disk of finite size with or without a central ...

Imprint of Pressure on Characteristic Dark Matter Profiles: The Case of ESO0140040
Galaxies, 2020 We investigate the dark matter distribution in the spiral galaxy ESO0140040, employing the most widely used density profiles: the pseudo-isothermal, exponential sphere, Burkert, Navarro-Frenk-White, Moore and Einasto profiles.

An Updated View of the Milky Way from Maser Astrometry
Universe, 2022 Astrometric observations of maser sources in the Milky Way, using the Very Long Baseline Interferometry (VLBI) technique, have been exploited to determine the spiral structure of our Galaxy. Several major spiral arms have now been pinpointed in the first

Halpha Kinematics of S4G Spiral Galaxies - III. Inner rotation curves [PDF]
, 2016 We present a detailed study of the shape of the innermost part of the rotation curves of a sample of 29 nearby spiral galaxies, based on high angular and spectral resolution kinematic Halpha Fabry-Perot observations.

The Astrophysical Journal, 2023 We investigate the resolved kinematics of the molecular gas, as traced by the Atacama Large Millimeter/submillimeter Array in CO (2−1), of 25 cluster member galaxies across three different clusters at a redshift of z ∼ 1.6.

Unified Rotation Curve of the Galaxy — Decomposition into de Vaucouleurs Bulge, Disk, Dark Halo, and the 9-kpc Rotation Dip — [PDF]
, 2008 We present a unified rotation curve of the Galaxy re-constructed from the existing data by re-calculating the distances and velocities for a set of galactic constants R0 =8 kpc and V0 =200 km s −1 .

Pseudo Rotation Curve Connecting the Galaxy, Dark Halo, and Local Group [PDF]
, 2008 We construct a Galacto-Local Group rotation curve, combining the Galactic rotation curve with a diagram, where galacto-centric radial velocities of outer globular clusters and member galaxies of the Local Group are plotted against their galacto-centric ...
