The method is considered of deriving the dynamical masses neighbouring galaxies from their relative motion. allows to constrain dark matter in galaxies, independently model matter. following pairs were studied, Milky Way and M31, Cen A M83 as well brightest Virgo cluster, M87 M60, M89, M49. obtained motion are smaller than total ΛCDM model. Â

Three experiments investigating the basis of induced motion are reported. The proposition that induced motion is based on the visual capture of eye-position information and is therefore a subject-relative, rather than object-relative, motion was explored in the first experiment. Observers made saccades to an invisible auditory stimulus following fixation on a stationary stimulus in which motion...

Human actions are complex dynamic stimuli comprised of two principle motion components: 1) common body motion, which represents the translation of the body when a person moves through space, and 2) relative limb movements, resulting from articulation of limbs after factoring out common body motion. Historically, most research in biological motion has focused primarily on relative limb movements...

We study the van der Waals friction between two flat metal surfaces in relative motion. For good conductors, we find that normal relative motion gives a much larger friction than for parallel relative motion. The friction may increase by many orders of magnitude when the surfaces are covered by adsorbates, or can support low-frequency surface plasmons. In this case, the friction is determined b...

It is now clear, contrary to previous conclusions, that motion may be conveyed by purely chromatic stimuli. The question considered here is how the mechanisms for assessing motion of luminance and chromatic stimuli differ. The dependence on contrast of amplitude thresholds for the perception of oscillatory motion was measured. The targets were Gabor patches modulated either chromatically along ...

Enigma is an op-art painting that elicits an illusion of rotational streaming motion. In the present study, we tested whether adaptation to various motion configurations that included relative motion components could be reflected in the directional bias of the illusory stream. First, participants viewed the center of a rotating Enigma stimulus for adaptation. There was no physical motion on the...
