To reveal the real pattern of processes in the mysterious galaxy, let us look at the negative image in Fig. 29. |

Comparing the lines of spiral with their reconstruction in the right-hand image of Fig. 29 which we conveniently repeated from Fig. 28b, we see that the authors of reconstruction incorrectly extended the green arm of spiral and quite inaccurately drew the internal arm of large spirals. In the negative image we clearly see two main arms; one of them, let us call it outer, goes behind the upper right corner of the image, and the internal one goes behind the bottom left corner. Just this spiral is absent in the reconstruction, and this is a very important point. Seeing two spirals, not one, we see all other details at their proper places. In the negative image we see that at large distance from the source of dynamic field, the spirals have quite regular shape, as we saw it in the images of compact galaxy M 51. As usually in compact galaxies, in this region of arms, intensive formation of second-generation stars occurs; their formation became possible due to the compaction of residual gas-dust cloud in the spiral arms. But in the near region of the source, above and below the centre of the image, we can see two clear distortions in the arms which blur the pattern. How do explain it the authors of this information? "Astronomers suspect that the object NGC 4622 has interacted with another galaxy. Its two outer arms are curved, which tells us of the external affection. The new image of Hubble shows that NGC 4622 has absorbed a small companion galaxy. This information is the clue of unusual leading spiral arms. Galaxies consisting of stars, gas and dust rotate very slowly" [25]. Should this supposition were true, the observed distortion in the shape of arms would be seen not in the near but in the far from source. While the main arms basically cannot be caused by the interaction with other galaxies. In this case we, first, would not see a spiral having quite measurable lead; second, we would have to suppose all spiral galaxies encountering such interaction, and third, this spiral slowly rotates and retains its shape, which would be impossible if it were curved because of interaction with another galaxy. We can reveal the real pattern, if we remember that the stellar mass in spirals occurs along the line of extreme of dynamic scalar potential. Then the distortion of regular spiral in the near of source can mean in the source some local unstable processes whose affection is limited by the near field. In particular, it can be caused by the distortions introduced into the general pattern by the bright stellar associations well seen in the left and right of the nucleus. And these can be the unstable processes within the nucleus. Anyway, to reveal the cause, this instability needs to be additionally studied, but its cause is undoubtedly within the nucleus of this galaxy. |
