On the Dwarf Galaxy Rotation Curve Diversity Problem [PDF]
Galaxies, 2018 In this paper, we show how baryonic physics can solve the problem of the striking diversity in dwarf galaxy rotation curves shapes. To this aim, we compare the distribution of galaxies of the SPARC sample, in the plane V2kpc-VRlast (V2kpc being the ...

Uncertainties in galaxy rotation curves [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 Assessing the likelihood that the rotation curve of a galaxy matches predictions from galaxy formation simulations requires that the uncertainties in the circular speed as a function of radius derived from the observational data be statistically robust ...

Pseudo Rotation Curve Connecting the Galaxy, Dark Halo, and Local Group [PDF]
, 2009 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 ...

Grand Rotation Curve and Dark-Matter Halo in the Milky Way Galaxy [PDF]
, 2012 A grand rotation curve of the Milky Way Galaxy is constructed, which covers a wide range of radius from the Galactic Center to ~1 Mpc, and is deconvolved into bulge, disk and halo components by least-squares fitting.

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.

Galaxy rotation curves from general relativity with renormalization group corrections [PDF]
, 2010 We consider the application of quantum corrections computed using renormalization group arguments in the astrophysical domain and show that, for the most natural interpretation of the renormalization group scale parameter, a gravitational coupling ...

Detection of the Keplerian decline in the Milky Way rotation curve [PDF]
Astronomy & Astrophysics, 2023 Our position inside the Galactic disc had prevented us from establishing an accurate rotation curve, until the advent of Gaia, whose third data release (Gaia DR3) made it possible to specify it up to twice the optical radius.

Galaxy Rotation Curve Fitting Using Machine Learning Tools
Universe, 2023 Galaxy rotation curve (RC) fitting is an important technique which allows the placement of constraints on different kinds of dark matter (DM) halo models. In the case of non-phenomenological DM profiles with no analytic expressions, the art of finding RC

Universe, 2022 The rotational velocity curve, which is the circular velocity profile of the stars and gas in a spiral galaxy as a function of their distance from the galactic center, plays an important role in the kinematic and dynamic investigation of spiral galaxies.
