Kinematics and dynamics of the M51-type galaxy pair NGC 3893/96 (KPG 302) [PDF]
, 2007 We study the kinematics and dynamics of the M51-type interacting galaxy pair KPG 302 (NGC 3893/96). We analyse the distribution of the dark matter (DM) halo of the main galaxy in order to explore possible differences between DM halos of "isolated ...

Rotation Curves of High-Luminosity Spiral Galaxies and the Rotation Curve of our Galaxy [PDF]
Symposium - International Astronomical Union, 1979 Rotation curves of high luminosity spiral galaxies are flat, to distances as great as r=49 kpc. This implies a significant mass at large r. Rotational velocities increase about 20 km/s across a spiral arm, as predicted by the density wave theory. By analogy, it is suggested that our Galaxy has a flat rotation curve out to r∼60 kpc, with V ∼ constant at

Hickson 62.I. Kinematics of NGC4778 [PDF]
, 2006 Detailed studies of the photometric and kinematical properties of compact groups of galaxies are crucial to understand the physics of galaxy interactions and to shed light on some aspects of galaxy formation and evolution.

The Rotation Curves of Galaxies at Intermediate Redshift [PDF]
The Astrophysical Journal, 1993 We have undertaken a pilot project to measure the rotation velocities of spiral galaxies in the redshift range 0.18 < z < 0.4 using high dispersion long slit spectroscopy obtained with the Palomar 5m telescope. One field galaxy and three cluster objects known to have strong emission lines were observed over wavelength ranges covering the ...

Evidence for universal structure in galactic halos [PDF]
, 1999 The late infall of dark matter onto a galaxy produces structure (such as caustics) in the distribution of dark matter in the halo. We argue that such structure is likely to occur generically on length scales proportional to $l \sim t_0 v_{rot}$, where ...

The rotation curves shapes of late-type dwarf galaxies [PDF]
A&A, 493, (2009) 871, 2009 We present rotation curves derived for a sample of 62 late-type dwarf galaxies that have been observed as part of the Westerbork HI Survey of Spiral and Irregular Galaxies (WHISP) project. The rotation curves were derived by interactively fitting model data cubes to the observed cubes, taking rotation curve shape, HI distribution, inclination, and the ...

Testing dark matter and geometry sustained circular velocities in the Milky Way with Gaia DR2 [PDF]
, 2019 Flat rotation curves in disk galaxies represent the main evidence for large amounts of surrounding dark matter. Despite of the difficulty in identifying the dark matter contribution to the total mass density in our Galaxy, stellar kinematics, as tracer ...

Study of rotation curves of spiral galaxies with a scalar field dark matter model [PDF]
AIP Conf. Proc. 1473, 74 (2012), 2012 In this work we study rotation curves of spiral galaxies using a model of dark matter based on a scalar-tensor theory of gravity. We show how to estimate the scalar field dark matter parameters using a sample of observed rotation curves.
