A Snag in the
Red Shift (NGC 4319
& Mark 205) |
 |
On October 3rd, 2002, the
STScI publishes on Internet the photo of the pair of
galaxies NGC 4319 and
Markarian 205, taken by the
HST.
These two galaxies have
nothing in common. The first one is a spiral galaxy situated at
80 million al (z = 0,006),
the second is a Quasar situated at 1100 million al
(z = 0,07).
Their Red shifts, being very different,
their visible nearness is due only to a fortuitous alignment in the axis
of aim.
But there is a |

But,
Halton Arp indicated the existence of a Bridge of matter
connecting these two objects. This Bridge of matter is invisible in the
image taken by the HST. (For more information on this subject,
we can consult the book "Seeing Red"
by Halton Arp - (Apeiron,
Montreal - pages 164 and 165).
|
 |
It is the reason which prompts us to process this
image. The result is in accordance with the claims of Halton Arp,
the bridge is there, and very much so.
This does not necessarily mean that this bridge
connects the objects. It is possible that it is an arm or a jet stemming
from one of the galaxies, and that these three objects present this
particular alignement.
But the hypothesis of the ejection of the quasar by
the parent galaxy cannot be excluded. And therefore it is necessary to
find the explanation of the abnormal red-shift
observed in Markarian 205.

We shall read with interest the Internet pages dedicated to the
controversy which developed around these galaxies connected by bridges
of material: |

Mister William C . Keel realized a good

to the one who was realized by our care and with a similar result.

very well informed

Let's examine closely the argumentation of those who
rejects the physical connection between NGC 4319 and
Mrk 205,
and let's attempt to bring some answers there.
-
The redshifts are very different.
This is the very statement that
is under scrutiny. Therefore, for Halton Arp, this statement cannot be
used as a valid argument, and rightly so.
-
The UV absorption, by the halo of the galaxy
NGC 4319, of the light emitted by Mrk 205; this would prove
that Mrk 205 is not inside the halo of NGC 4319.
There is no
evidence for
Mrk 205
being "beyond" or "inside" of the halo of NGC 4319. In both
cases, for a terrestrial viewer, the light of Mrk 205 crosses all or
a part of this gas and is therefore attenuated. As we don't know how the
light is attenuated, we are not able to deduct anything.
The only way to solve this problem would be to redo, at same wavelength, the
same kind of measurement that
J.N. Bahcall et al, made, but on the three objects : the
galaxy NGC 4319, the bridge of matter and the Quasar Mrk 205.
From the analysis of the results one could finally resolve this
polemic.
-
On the other hand a
meaningful jump of the
absorption, between these objects, would definitely invalidate his
claims.
-
Similar attenuations would show that Halton Arp
was right.

On June 29th, 2009 a friend indicates us the existence of an image
of NGC4319 in
Aladin data base. This image is of inferior quality.
The resolution is weak and it contains a lot of noise. However we
can obtain a colour version from it. It is the colour version which
we hurry to process. The strand connecting
NGC4319
to Mrk 205
seems then very sharply. So we have a
confirmation of this strand from another image. |
