PUBLISHER'S REMARKS

GALAXIES CAN ALSO CAUSE THEIR OWN COLLISION CLUES

The idea of a missthrown baton hurtling end over end while simultaneously twirling sideways as a model for galaxy deep space motions is recent for 'Galaxies In Chaos' interpretations and did not come easily.

NGC 2442 - A MISSTHROWN BATON TWIRLING END OVER END



It seems the 'baton' model may need revisions. Mainly, not all galaxy parts are in motions at the same speeds. It is already known that galaxies with developed spiral structures are in differential and slipstream motions, that is, that even if at similar velocities inner to outer, longer outer lengths means galaxies are disproportionately in motions inner to outer like clock springs being wound up or unwinding.

This however assumes all parts of the galaxy are rotating in the same planes one part to another, in other words holding their basic shape (as would a bunch of bananas) while slowly morphing on different 3D vectors due to differentials over time.

Another motion has come to mind, which is, that the galaxy may not be in coherent object transmission through space. In other words, one arm may be in motions at a distinctly different speed and direction relative to another.

This means one part of a galaxy may be folding over and/or through another part of a galaxy.

NGC 1365 - JACK-KNIFING MAIN ARM



For instance, the puzzling sharp angled (upper left) arm in Ngc 1365 may be jack-knifing. Jack-knifing means the arm is actually folding over onto the bar (or visa versa) in pivoting on different collective vectors than is the central bar and/or the lower right arm.

Certainly, without question, the upper arm is being churned in a hard force tightly to the right, as revealed in the galaxy's doppler shift profile where red shows extreme torquing (away from us) in the upper end where the upper arm joins the galaxy central body in an extremely dynamic hub (with a spray of short arms attached looking not unlike a bunch of bananas in rotating motion).

That this upper arm is also jack-knifing is purely supposition, and should be regarded as merely a supposition, but, watch how insights arrive on center stage when the supposition is explored for action.

If jack-knifing, it would mean in time that the upper jack-knife arm will crash into the galaxy's main body.

Even though a self injury, the crash would have aspects similar if not identical to a collision, with damage and distruption within the body especially if the jack-knifing arm is very slowly moving in its jack-knife so that plenty of time is available for gravitational densities to pull and torque.

It is possible that many collision clues seen in pretty much any galaxy are due in part to jack-knife same-body collisions rather than to external incoming projectiles or colliders. For instance galaxies in a sailpast or sideswipe collision will have disruption occur more intensly in material forms on the sides closest to each other in the dustup. But, these 'damages' will soon enough migrate at high speed to other parts of the galaxy and be visible in the form of   Jets,   Intruders,   and   Polyps.

A long arm from one galaxy coming in from above upon another galaxy's long outer arm will cause both galaxy arms to tug vertically toward each other, in both approach and departure in the dustup collision, forcing new total angular momentum vectors independentaly into both arms, so that over time, it is possible that one, or both arms, can crash into a galaxy's main body because of the 'vertical' momentum component imparted by the dustup. Vertical component momentum is relevant only if all other angular momentums in a galaxy were basically uni-plane along a basic single horizon before the dustup.

Self targeting crashes and bruises by a galaxy's own part(s) in non uniform horizon plane motions can easily explain many collision clues such as jets, polyps, and intruders which undoubtedly all also have external collision causes with other galaxies.



For instance hot new star birth areas proliferating in the LMC are being formed as we speak by a wrangle underway between an original smaller LMC and another small galaxy, whose clues are presented here as a second galaxy comprising LMC herein called 'Glommer'.



NGC 4038 - LONG ANTENNA ARMS



Even the formation of long antenna arms such as seen in Ngc 4038 might be engineered by a jack-knife collision, by an arm passing through its galaxy's body.

For instance, suppose the jack-knifing upper left arm in Ngc 1365 (shown above) is flipping over as it jack-knife's down, the upper outermost hump flipping overhead in a long-arm arc toward us even as the arm continues to fold downward toward the main body (central bar in Ngc 1365).

Eventually, the result of that motion (jack-knifing and swinging over longtitudinaly) would result in the upper left arm landing as a lower left arm, its hump now downward instead of upward. In passing through or near the main body (eg) central bar, the jack-knifing arm could be stripped of much material left behind in chaotic rubbles in the main body's high gravitational components.

The resulting jack-knifing arm, now long, and thinned, could now look like an 'antenna' in its new position. Assuming the original right arm and central main body are in a basic uniform topologically sustaining tumbling motion, the result of the completed jack-knife would could probably look very much like two antenna arms such as currently seen in Ngc 4038, except, two cores would not be seen since only one core was involved in the self-body crash as the jack-knifing arm crashed into and on through the main body of the galaxy.

To create an antenna galaxy out of bar galaxy Ngc 1365, all that is needed is for the upper left-aimed arm to fold over jack-knifing, and crash through the central bar. The picture is simply envisioned in mind's eye. Is it theoretically possible? It might be. Concider the doppler shift motions for Ngc 1365. The doppler image does not instantly support a view that the upper arm is jack-knifing downward. In fact, the whole object is tumbling in toto in rotation to the right on a north/east vector. For jack-knifing to be evident, you would expect to see stronger blue shift motions along the upper leading edge of the upper arm indicating uniform motion of the upper arm generally in our direction, even as the whole object tumbles turning to the right.

Leading edge indicator is not seen, or at least, not immediately recognizable so it is possible the upper arm is not jack-knifing in a way that will soon enough bring it crashing through the central galaxy body to eventually create a new antenna arm. It is self evident however that the upper arm is in a mode of extreme torquings in personal motions outside of the main motions of the galaxy object at large. In thus having unique torgue motions, that upper arm surely will someday muscle up another part of this galaxy.

The upper arm of Ngc 2442 seen in the opening image above, is vectored to the right, but, is also in an out of synch torque with the main central body and lower arm, showing a slight degree of jack-knifing, seen at its best viewing the image in stereo by overlaying the two side by side images together by eyesight.

Extrapolating outward into the dominion of galaxies at large, instances of galaxy local folding and jack-knifing will be seen to be commonplace, based on insights gained from the analysis of the above galaxies profiled.

For instance, multiple passes of one part through another, in aftermaths of collisions, seems to be the current primary constructor mode of galaxy Ngc 6951.



Galaxy Ngc 1232 also seems to be getting seriously busted up by its own parts crashing through each other, accounting for many of the small arm segments accrueing through evolutionary time.



This is the sustance of the opening 'remark', that - galaxies can also cause their own collision clues. GM. Dec 21/2001.
