Such braking is an important process because it assures a source of matter of relatively
low angular momentum (by the standards of the interstellar medium) for the formation of stars and planetary systems.
«We demonstrated that
the low angular momentum of ellipticals is mainly originated by nature in the central regions during the early galaxy formation process, and not nurtured substantially by the environment via merging events, as envisaged in previous theories.»
Despite this change of perspective, the origin of
the low angular momentum observed in local ellipticals still remained unclear.

It is a concept that arises in quantum mechanics that can be thought of as being similar to
angular momentum: in this sense higher spin corresponds to the quarks orbiting each other faster than those with a
lower spin.
4) I say that when air moves from a location with high rotational velocity (m / s following a circumference) to a location with a
low angular velocity, the air will conserve
angular momentum and hence be diverted at right angles to the the initial impetus, resulting (at the poles) in a vortex around the pole.
The ice that was at higher latitudes contributes less
angular momentum than the water that is now at
lower latitudes.
We demonstrate that the combination of
lower estimates of the 20th century GMSL rise (up to 1990) improved modeling of the GIA process and that the correction of the eclipse record for a signal due to
angular momentum exchange between the fluid outer core and the mantle reconciles all three Earth rotation observations.
This graph displays the close connection between the global
angular momentum of the atmosphere derived from wind analyses (darker red curve, scale on right) and the observed changes in the length of day (lighter green curve, scale on left), after removing
low frequencies, for the years 2000/2001.
This is associated with a poleward shift of the westerlies at the surface (see Section 10.3.6) and in the upper troposphere particularly notable in the Southern Hemisphere (SH)(Stone and Fyfe, 2005), and increased relative
angular momentum from stronger westerlies (Räisänen, 2003) and westerly
momentum flux in the
lower stratosphere particularly in the tropics and southern mid-latitudes (Watanabe et al., 2005).
But it defines a spacing between the two
lows in solar activity and the two highs in
angular momentum perturbation of 2500 years.
