Zooming in on NGC 7049, a mysterious looking galaxy with globular clusters dotted throughout its halo.

  • @CACBCCCU "Possibly every distinguishable form within the halo, excepting at least the halo itself, the ring, and presumably the bright center, could be a projection effect" should be "Possibly every distiguishable light pointlike object seen within the halo, excepting the bright center, could be a quasar projection effect." However the very bright point at around 7 0'clock I am not at all sure about, maybe it's much closer, but it's right over the ring. Maybe a giant star feeding off the ring?

  • I'm compelled to analyze this galaxy, but it's such a complex thing, maybe too much to handle. For reasons difficult to elaborate, it reminds me of a tilted pinhole lens with a light source in it, forgetting the ring for a moment. Possibly every distinguishable form within the halo, excepting at least the halo itself, the ring, and presumably the bright center, could be a projection effect, if that happened to be the case. Pinhole-type lensing can be related to an anti-deSitter space, I suppose.

  • At 0:42 there are two objects outside of the halo and both seem more like out-of-focus specular effects, after that, no bright spots are visible outside the halo, where the out-of-halo darkness should make such objects easy to spot if they were there. More indications to me that unusual gravitational lensing effects are in play here.

  • "I doubt we can resolve line spectra small enough to focus on the globular clusters" should be "I doubt we can spatially resolve line spectra small enough to focus on the globular clusters," but having thought about it a bit more, it seems like it should be possible. At least one of the objects (it's around the 5 o'clock position, right on the ring axis) that might have been identified as a cluster definitely looks like a lensed full-sized galaxy image to me, but not a quasar.

  • Found what I mentioned before, in "Project Universe - Quasars (2 of 4)," which is where Arp notes that quasars (high redshift) appear to be positionally-correlated with much closer galaxies (low redshift). I think it's consistent with the light rays of quasar images being gravitationally-lensed divergently, meaning by a concave type of lensing action, through the closer galaxy. The same thing seems to be happening with at least some of the "globular cluster" objects seen close to NGC 7049.

  • I doubt we can resolve line spectra small enough to focus on the globular clusters so often invoked in describing such galaxies as this one, so we can't get a measure of their distances that is not dominated by the effect of the bright core and its red-shift. I think it was Aarp who once pointed out how quasars seem to line up. Maybe it is a wide-spread lensing effect that lines up lens-formed quasar-based images.

  • A theory about NGC 7049 I have is that the halo is basically a lensing effect, if we were closer to this galaxy the ring would of course appear larger, yet the apparent halo size may not change much. The simplest gravitational lens differs from a normal optical lens in that its effect is spherically symmetric - the same type of lensing effect can be created by it along any axis passing through such a lens. I guess ring galaxies can create a 3-element gravitational lens that has axial asymmetry.

  • That most of these globular clusters are below the galaxy (NGC 7049) is another indication that they are galactically-lensed objects, with the tilt of the galaxy dictating their position. The halo is acting much like a lens that spreads out the light from lensed objects (concave lensing) rather than gathering the light together like a typical gravity lens (convex lensing). It's an effect from regions with near zero, or even negative, energy, formed I suppose in accordance with quantum gravity.

    "well beind" = "well behind" or "far behind"

    Seems science does not appreciate that gravity in its constant form (single particle, not accelerating) has a wave property built into it. Newton left out a cosine factor with a wavelength of galactic scale, Einstein tried to use negative gravity to do what the negative half-cycles of the cosine factor do, but as a (cosmological) constant equal to negative gravity. The dominant wavelength of choice is, as noted, about 10^21 meters.

  • Notice how many of the so-called "globular clusters" seem to be close to the edge of the "halo" and even right on the edge. It's a convex lensing effect on things located well-beind the galaxy, it is gravity lensing in opposite form to the only kind of gravity lensing scientists normally seem capable of acknowledging.
