LONG ANTENNA ARMS IN GALAXY COLLISIONS
I wish to address the perplexing situation of long antenna arms forming
in galaxy collisions, in some instances, not in other instances of
collision. Further, instances are seen where only one not two long
antenna arm has formed. Thirdly, some antenna form with an initial
plough, or explosion.
The answer seems to be intense long distance galactic 'cometary' winds.
Details are in the longarms.htm page.

Concidered
a bar galaxy with
long extended arms, my semi
safe bet is this is a pummelled galaxy
with two antenna trails. For instance, a jog is
in the process of being created, as it happens, by the
small nearby upper galaxy whose end streams in a curve back
toward the jog. We see here a galaxy does not have to pass
through an arm to create a jog, it only has to get
close enough for gravity's suck power to do
its work. The lower arm, with a slight
sweep showing it is swinging
toward the left, ends
abruptly in a
warble in
empty
space
signalling
the beginning of a
prior collision event, the
upper trail dissipates stretched out
in a time signature event, such as this
The green image immediately above has in it a small hooking tail
off the bottom of the bright yellow object. Whatever
the bright yellow object is, it has a
filament hooking from it
WHY THE UPPER TRAIL IS SPREAD OUT
I think
I have it. The
little guy has sailed in
along the long upper antenna disturbing
it into a spread out roil, and is just now (the
little guy) bursting free of the gravity grab, into
free space, the 'jog' the point where the little
guy has burst free of the arm. The histrogram
image (fully bright) above, provided the
final clue, where you can see faint
trails from the little guy
vectored straight
back to the
long arm.
Evidence is
good enough for me.
The fact that hot new blue
stars fall all along the upper left
arm puzzling astronomers world wide, is proof the
little guy has sailed along the arm's length kicking up shit

Other galaxy thugshots and what they reveal. Some of these
were made from highly enhanced DSS deep space images in
which each galaxy is a small center object surrounded
by a wide field black background. For example here
is colliding galaxies NGC 4038. Hardly an image
to print as a poster. Yet watch what happens
when the deep field is enhanced amplifying
the flux of weak photons radiating from
the larger superform of this galaxy.
The longer lower antennae arm
actually jogs around and
heads back along the
other direction.
Something has
jogged the
arm at
that junction.
It may have been another
encounter with a passerby or even
its current dance partner. In any case, the
appearance of the long ago jog is an event whose
residual legacy is being dragged forward into
time at the present, energy from the
original event still hot enough
to radiate today. Here is
an example of what
deep space
drag
can do,
and how drag
begins drawn out from
colliding galaxies. In the next
images featuring 'Stephan's Quintet trails
are being drawn out of one galaxy by another, each
trail initating at an arm. The filaments drawing out are
quickly converging. Soon they will be a long glowing
phosphor trail arcing back showing the present
path of the galaxy whose arms created
the ghostly connections to the
other galaxy, the ghost
stretching out
thinning
like
taffee
being pulled.
Now you know how galaxies
can have long antennae because you can
see one in the process of being created this very day

The
extra jog
turning back at
the end of the 'history'
trail is not seen in normal
high enhancement levels, forcing
two conclusions, the 'jog' is
really there, the 'jog'
is false
Certainly
the explosion
back on the time line
where the 'antenna' begins, is real
Another
NGC 4038
deep space view
shows the 'history' event
in more detail, but, nothing of the
'jog' is seen in this enhanced image either,
although a 'history' event of major impact is
self evident where the end of the tail
ends in what seems to be some
kind of explosion
Dimpled
chads in the
image (two) are in the

or are not cannot be deterimed here

Please
note a round
percussive explosive
beginning to the long tail. A
similar percussive starting node is seen
in the Antenna galaxies, however the
Antenna node is only seen in one
image, view it via the Antenna
link immediately above
Explosions
that begin 'antenna'
in galaxies are not all that
rare. Here is a colliding galaxy image
which serves two purposes. First is the astounding
amount of missing mass enhancement upon the original
image reveals. Second is the 'explosion' actually
still has signal image of the other galaxy

A long
scorpian tail
winds out in one direction
from a previous encounter with another
galacy. Meantime a whole new tail is in the process
of being created. Wisps being drawn out from each of the
arms quickly converge like taffee being pulled. In time, as
these two galaxies drawn further apart, the taffee-pull
wisps will separate but some legacy will be left
at the point where the wisp separates, even
though the departing galaxy will be
long gone from the stage of
the current encounter.

The
original
Hubble image
shows nothing about
a tail being sucked out of
a galaxy, nor of the long tail
already sucked out from a collision
event a long time ago. Further,
all that you see extra in
the enhanced image, is
'missing mass'

NGC 5426
Color version from Subaru electronic telescope
Another
tail is being
drawn out, in realtime,
in the galaxy tangle known as
ngc 5426. No spanking Hubble vision
for this item. What you see here seems
to be best available, a so-called 'histogram'
version found at a Hubble research site which had
mostly papers and few (very few) images. Wide drag
is being sucked out of arms of the smaller by
the larger (more gravity?). Someday the
drag will draw together into a long
strand (like taffee being pulled)
and will be another antenna,
or so goes my theory

This
image, a
real weirdo due
to the long length of its
antenna, is thought by the latest pro
contenders to reveal a dark galaxy, the long arm
being sucked into the dark galaxy's gravity, talk about
sucking up a long strand of noodle from soup. But there is
no sign of anything there, not even a Star Trek shimmer on the
enterprise's viewscreen. Instead the image reveals when enhanced
a history of greater activities, streakers rising from the upper
end mean something has happened there in the past, and a short
prong straight out right means something has happened
there as well. Space Anomaly judges (me) vote
another large galaxy has collided and
sailed on over the horizon. If
true to form, the antenna
has been drawn out of
this (smaller body)
in the collision, the
end is a time stamp in history
of when the collision event first began
As much dim mass as this image is going to give us,
it looks ugly

YO-YO ARMS
This looks m u u u ch better now
Looking
like a yo-yo,
with two long thin
arms winding outer circle
parallel paths, this galaxy has
the likeable feature of showing us a
very nice example of yo-yo arms in
a galaxy, which are commonplace,
for instance yo-yoes are
obvious in the
Stephans
group, and
a new yo-yo seems
to have just been formed in Ngc 6745
NGC 6745 WITH A BRAND NEW YO-YO ?
Two yo-yo's - the lower one interrupted
It appears
the barge (big)
was closer in forground
space when the encounter event
first initiated with the dingy making
contact in rearspace at the upper left, as
the dingy continued to more around the rear flank
of the barge the barge was slowly drifting backward,
causing the thin band of excitement to gradually
narrow closing toward the main body and
as it happens left the event when
reaching the right tip of
the barge the two
now drifting
apart the
barge
drifting
rearward the
dingy drifting to
the right and continuing
slowly forward. This logically
seems to explain why the gap is wider at
the upper left of the barge where the yo-yo starts
and the dingy has actually drifted in on an arc over the barge.
As for deep space motions, more than one view is possible -
the barge is faster moving and came in from the
lower right heading west, clipping past
the dingy. The dingy is faster
moving coming on in
from the
upper rear
left clipping fast
past the barge in a forward
pass - both are also possibles, in lack
of a larger deep space view to see the whole situation

GHOST ARMS
Triangulum
shows all the signs
of having been significantly
folded by its brush with bruce (a
sideswiping galaxy which cliped away the
left edge). All of the folds and wrinkles are
upthrusts aiming to the left, as are the folds
and crinkles in the arms, clear cut signs that
Triangulum fluididically compressed from
right to left as the left edge
pressed against bruce,
not with a
grinding
racket, but a
huge long slow motion r u s s s h
The
enhanced
image shows ghost
arms in extensive reaches
below the left side incision, the
dim ghost arms are all below the surface
plane occupied by the many brightlit
arms on the right side
Because
the swiped out
linearity shows ghost
arms curling thickly underneath
in very dim matter, it tells us that
the sideswiping bruce sailed along the
above helm of Triangulum shaving away the
top but not being full broadside did
not wipe out the left side
understructure. So,
class this as
an eclipsing
sideswipe, rather
than a full blown broadside

'Wings' are
antenna in the making
Clumping, shows
the long antenna 'wing'
is already starting to separate
Antenna
wings in the
making, to unnamed
spiral galaxies from one
Hubble very deep space image,
The antenna already long drawn out
will separate (if the two galaxies are
drifting apart) leaving at least one if not
two 'antenna'. This image raises some serious
questions. First, the wind around the smaller
galaxy means rotation there has taken the
wing around as if winding the spring
of a clock counterclockwise. The
serious issue is what has
allowed the wind to
stay intact
despite
such long
distance. Some
strength is contained
in the winding 'wing' making
it stay coherent and unchanged over
a long time (galactically speaking). It comes
to mind that angular momentum in the property components
in the 'wing' arm is coherently at the same its whole length
such that it drifts along as a wisp of smoke without degrading.
The counterclockwise wind around the smaller galaxy suggests
the angular momentum was contributed mostly by the
smaller galaxy and gravity in the small
galaxy is winding the 'wing'
arm up tighter

Stereo
shows the

gathered in undulating
drifts, none in a flat sheet and
there is no strong priority in
alighnments of the drifts
Curved cell walls
can be seen separating
drifts into major organizations,
each is separate with its own dynamics
